1.1.1 Summary of Regional Board WDRs
The state is divided into nine regions, each with a regional water board. Carlsbad is in
Region 9, which is under the jurisdiction of the San Diego Regional Water Quality Control
Board (SDRWQC). On February 14, 2007, the SDRWQC issued Order R9-2007-005,
Waste Discharge Requirements for Sewage Collection Agencies in the San Diego
Region (WDRs), which includes additional requirements more stringent than the State
Board’s General Order. The Regional Board WDRs also reference the Water Quality
Control Plan (Basin Plan), adopted by the Regional Board, which designates beneficial
uses, narrative, and numerical water quality objectives, as well as prohibitions which are
applicable to the discharges prohibited in the Regional Board WDRs. The Regional
Board WDRs also requires notification and reporting of Private Lateral Sewage
Discharges. The Regional Board WDRs are included as Attachment A3.
1.1.2 Application for Coverage Under the State Board WDRs
The city applied for coverage under the general WDRs in 2006 for one collection system
and was assigned a Wastewater Discharger Identification Number (WDID) of
9SSO11209 in the California Integrated Water Quality System (CIWQS).
1.2 SSMP Goal and System Management Objectives
The goal of this SSMP is to provide a plan and schedule to properly manage, operate,
and maintain all parts of the city’s sewer system. The overall goal of the city’s SSMP
program implementation is to prevent and minimize sewer spills and mitigate those that
do occur. Specific goals of our SSMP program implementation are as follows:
• Protect public health and safety and the environment
• Properly manage, operate, and maintain all portions of the city’s wastewater
collection system to minimize spills
• Provide adequate capacity to convey peak wastewater flows associated with the
city’s design storm event
• Manage infiltration and inflow (I/I) in a cost-effective manner
• Include employees involved in collection system program implementation in the
strategic planning process for the collection system
• Perform all operation and maintenance activities in a safe manner
1.3 SSMP Update Schedule
Pursuant to the General Order, the city conducts program monitoring and triennial audits
of its SSMP, prepares SSMP updates, and implements planned activities to achieve city
collection system program objectives. This SSMP update was prepared upon completion
of the most recent SSMP Program Audit, dated January 17, 2025.
The schedule for auditing and updating this SSMP is provided in Table 1-2. Element 10
of the SSMP includes a longer-term schedule for SSMP audits and updates.

Since October 2015, the city’s sanitary sewer overflow (SSO) rate has consistently
averaged below one spill per 100 miles of sewer pipeline—well below Region 9’s
average of 2.3 per 100 miles. This low spill rate reflects the effectiveness of the city’s
proactive and preventive maintenance programs. Based on this performance trend, the
city has determined that its current strategies and programs are effective and appropriate
to maintain system reliability and minimize SSOs.
1.4 Sewer System Asset Overview
The collection system owned and operated by the city conveys wastewater via
approximately 268 miles of gravity mains, 3.9 miles of force mains, and 11 lift stations.
Currently, an average wastewater flow rate of approximately 6 million gallons per day
(MGD) is conveyed by the collection system. Approximately 94 percent of service
connections are residential, 0 percent are industrial, and 6 percent are commercial.
Table 1-3 provides a summary of the collection system assets for each collection system.

materials, maintenance holes, sewer pump stations, pressure pipes, and valves. The
wastewater system maps were originally created based on record drawings, system
video inspection, and field verification. The GIS tool also includes an up -to-date map of
the city’s storm drain system.
The city also utilizes the following data management systems for various purposes, as
described below:
• GraniteNet: Sewer inspection CCTV software. The city documents observed
defects using the National Association of Sewer Service Companies (NASSCO)
Pipeline Assessment Certification Program (PACP). GraniteNet has a GIS
interface which makes it easy to see problem sewer pipes on a map. Issues
found during CCTV inspection are evaluated and solutions are developed on a
case-by-case basis. Tasks are created in Cartegraph and synced with
GraniteNet. Completed inspections are synced nightly from the TV truck into
Cartegraph. Tasks are auto-created for follow-up activities, such as re-cleaning
and repairs, and assigned to the Utilities Maintenance Planner to schedule for
staff to complete. Tasks are auto-created for data corrections and assigned to
the Associate GIS Analysts.
• Cartegraph Asset Management: A computerized maintenance management
system (CMMS) used for managing maintenance activities. Utilities maintains a
log of all cleaning activities by its 40 cleaning zones in its CMMS, Cartegraph.
The current work management system interfaces with the GIS attributes and
details the size, material, and location of each pipe cleaned, as well as the
equipment utilized and any relevant remarks observed during the cleaning. The
city began utilizing Cartegraph in July 2024 to assign and record all work for
maintenance and operations staff, including preventative maintenance and
repairs.
• SmartCover: Technology used throughout the sewer system in areas of higher
risk of overflow and in manholes upstream of the lift station’s wet well to monitor
flow and provide real-time alarms to prevent sewer system overflows and
optimize sewer cleaning.
• SCADA: Supervisory Control and Data Acquisition system used to collect and
store pump station and wastewater treatment plant operational, instrumentation,
and alarm data.
• InfoSWMM: GIS-integrated hydraulic and hydrologic modeling software used for
planning, analysis, and management of wastewater and stormwater systems.
The city currently utilizes InfoSWMM as its primary hydraulic modeling tool and is
exploring other software options and may transition to another hydraulic
modeling tool in the future.
• InfoAsset Planner by Innovyze: The city selected InfoAsset Planner by
Innovyze to support capital planning through a risk-based model and decision
logic framework for forecasting the renewal needs of gravity sewers and
manholes. The city will continue to utilize the results generated by this software,
and may transition to a new capital planning tool in the future.

• Tableau: Data visualization and business intelligence platform used to create
interactive dashboards and reports. The city uses Tableau to pull data from
GraniteNet and Cartegraph, enabling efficient dashboarding and real-time
monitoring of asset condition and maintenance activities.
1.4.2 Lateral Ownership and Operational Responsibilities
The city does not own any portion of private service laterals. The private property owner
is responsible for the entire length of the lateral, including maintenance and repair from
the building connection up to and including the wye/saddle connection at the sewer
mainline. The city does own approximately 2 miles of sewer laterals on city-owned
property that are managed by the Facilities Department. The Facilities Department
oversees preventative maintenance and emergency response activities. While the
Wastewater Division is not responsible for these laterals, it may assist in reporting spills
or other incidents as needed. Ultimately, the city holds responsibility for the condition and
performance of city-owned laterals.
1.4.3 Unique Service Boundary Conditions
The City of Carlsbad is located in North County, San Diego County, approximately 87
miles south of Los Angeles and 35 miles north of downtown San Diego. It is part of the
San Diego-Carlsbad, California Metropolitan Statistical Area and is recognized as a
tourist destination referred to by locals as “The Village by the Sea.” The city contains
three lagoons and one lake and borders over 3 miles of Pacific Ocean coastline.
Carlsbad’s sewer service area covers approximately 74 percent of the city boundaries.
The remaining 26 percent is served by other wastewater agencies and sanitary districts.
The city does not own any portion of the service laterals connecting buildings on private
properties to the public sewer main; however, the city does own and maintain some
enrollee-owned laterals, approximately 2 miles in total, with some located outside the
city’s managed sewer system.
The city is a co-owner of the Encina Water Pollution Control Facility (EWPCF), which is
operated by the Encina Wastewater Authority (EWA) and treats wastewater from
Carlsbad and surrounding jurisdictions. Within Carlsbad ’s service area, there are also
regional interceptor sewers that are owned and maintained by neighboring agencies but
traverse the city’s jurisdiction. These facilities remain under the operational responsibility
of their respective owning agencies. Coordination with adjacent agencies is required to
manage these flows.
The Agua Hedionda and Buena Vista lift stations, operated and maintained by EWA, are
jointly owned by the City of Carlsbad and the City of Vista/Buena Sanitation District, with
the City of Vista serving as the majority owner for both facilities. EWA manages these
facilities under its Remote Facilities Comprehensive Asset Management Plan (R-CAMP),
which outlines the capital assets, maintenance strategies, and long-term planning for co-
owned infrastructure. All maintenance activities are coordinated by EWA and Capital
Improvement Projects (CIPs) under $50,000 for these lift stations are carried out by
EWA. Spill response is a coordinated effort between the City of Carlsbad and the City of
Vista/Buena Sanitation District to ensure timely and effective mitigation.

3.7 Authority to Obtain Easement Accessibility
Agreements When Applicable
The city routinely accesses all sewer maintenance holes and cleans all pipelines on a 3-
year cycle. Easements are currently in place wherever necessary to support this
maintenance schedule and provide access to infrastructure on lands not owned by the
city. However, access to a small portion of the system is limited due to environmentally
sensitive habitats, despite the presence of easements in these areas. The city maintains
a comprehensive GIS layer that documents all easements, including associated
document and agreement numbers. When new easements are required, the city follows
an established acquisition process. This includes coordination with the Community
Development Department, Land Development, Engineering and the city’s Real Estate
Manager during the preparation of legal descriptions and plats, engagement with
property owners, and final recording of the easement documents with the county.
Section 18.40.030 of the city’s municipal code provides the city with the authority to
obtain easement accessibility agreements:
• Any person who constructs or causes to be constructed any building in the city
shall have provided by means of an irrevocable offer of dedication, grant of
easement or other appropriate conveyance, as approved by the City Attorney,
the rights-of-way necessary for the construction of any street, highway, or alley
as shown on the circulation element of the general plan, any applicable specific
plans, or as otherwise required by the City Engineer in accord with an
established street system or plan. Rights-of-way shall also be provided for any
improvements to existing facilities including rights-of-way for storm drains or
other required public facilities. All rights-of-way shall be accompanied by a title
examination report and all liens and encumbrances shall be removed or
subordinated to the city’s interests.
Section 6.10 of the city’s Engineering Standards Volume 1 – General Design Standards,
Chapter 6 – Design Criteria for Sewer Facilities states that all sewer mains not located
within the public right-of-way shall be located within a public utility and access easement
granted to the city.

4 Operation and Maintenance Program
4.1 Up-to-Date Map of the Collection System
A comprehensive set of sewer maps show all the features of the city’s sanitary system.
These maps are maintained and updated through an efficient workflow involving field
crews, operations and maintenance staff, and GIS professionals.
4.1.1 Procedures for Maintaining and Providing Access to Water Boards
Staff
State Water Board or Regional Water Board staff can gain access to system mapping by
contacting an LRO for the City of Carlsbad, using the contact information provided in
Section 2.2, Table 2-1.
4.1.2 Procedures for Maintaining and Providing Access to City Field
Staff
The City of Carlsbad’s Utilities Department employs a GIS Associate Analyst (Analyst) to
maintain the inventory of wastewater infrastructure in the city’s GIS system. There is a
process in place for the Analyst to be notified of any new development that has been
approved in the city. If any public wastewater infrastructure is being added with the new
development the Analyst will add the assets to GIS with a status of “Future”. Field staff
can see these assets on their field maps within 24 hours. These assets are the
responsibility of the developer and are shown in a different color until they are
constructed and accepted by the city. Once the city accepts the infrastructure and issues
a Notice to Commence Maintenance, the Analyst turns the status to “Active” in GIS and
the assets show up in the city’s CMMS within 3 days where they are then incorporated
into the maintenance programs.
Wastewater staff are all issued iPhones and iPads and use an ESRI field map
application with an up-to-date map of the collections system. Cartegraph also has a map
feature that shows where assigned tasks are located. Field staff have a procedure in
Cartegraph for identifying discrepancies between the GIS data and field conditions, and
their feedback is assigned to the Analyst to research. If warranted, GIS updates are
made based on feedback from field staff. The changes will show up on the field map
application within 24 hours and in the CMMS within 3 days.
4.2 Preventive Maintenance Program
Table 4-1 outlines operation and maintenance program activities, the three bullets
specified in the General Order, and the scheduling and data collection system used. The
following sections provide additional details for each operation and maintenance program
activity.

The Wastewater Division has been using a CMMS to record operations and maintenance
data and work history since 2006. In July 2024 the city switched to Cartegraph and all
wastewater operations and maintenance activities, and associated information, are
recorded in that system. Cartegraph is integrated with the city’s GIS system and
automated processes are in place to synchronize asset inventory data between these
two systems in a timely manner.
The core operations and maintenance activities performed by the Wastewater
Operations and Maintenance staff are listed below. These activities are scheduled by the
Utilities Maintenance Planner with input from Operations and Maintenance staff. Field
staff collect data during the performance of these activities and enter the data into the
CMMS. The city uses this data to fine tune the scheduled activities, identify problem
areas that are candidates for increased maintenance, and provide information used to
identify rehabilitation and replacement needs. Data that is collected includes (but is not
limited to): debris information, condition assessment information, discrepancies between
GIS data and what’s found in the field, how equipment is performing, root intrusion and
other field observations.
Gravity Sewer Main Cleaning – The city cleans collector gravity sewer mains with a
diameter of 15 inches or less on a 3-year schedule. Each sewer main is assigned a
cleaning frequency based on location and debris found during previous cleanings. New
sewer mains are assigned an initial cleaning frequency based on other sewer mains in
the area. These frequencies can be adjusted as data is gathered. Cleaning frequencies
range from quarterly to every 3 years. Problem areas with known structural defects

annually. PVC sewer mains in areas that historically have had no problems can be
cleaned up to every 3 years. Data is reviewed annually to see if any changes to the
cleaning program need to be made. Larger diameter (over 15 inches in diameter)
interceptor mains are considered self-cleaning. They are cleaned as-needed when they
are inspected with CCTV.
Manhole Inspections – Manholes on collectors are visually inspected when the
associated sewer mains are being cleaned. The inspection frequency will usually be the
same as the associated main. There are some manholes that have a history of debris or
root build up. The city is developing a program to spot check those manholes between
cleanings as needed. This program is expected to start in Fiscal Year 25-26. Whether
during cleaning or during a spot check the manholes are visually inspected from the top
of the manholes and are given a score of 1 (like new) to 5 (needs immediate attention).
Field staff have laminated reference sheets with pictures showing examples of what a
manhole at each score looks like in an attempt to generate consistent condition scores.
Condition scores are recorded in Cartegraph. Manholes are also visually inspected from
the bottom during CCTV inspections but no scores are assigned. If the CCTV crew sees
something concerning it is recorded in Cartegraph and the supervisor may be verbally
notified as well. The city is currently developing a plan to inspect manholes deeper than
20 feet with a tool that can conduct 360 degree scans as they cannot be seen well
enough for a visual inspection to be considered accurate. Manholes on interceptors are
inspected when the mains are televised by a contractor using MACP. They are also
visually inspected from the top and scored 1-5.
Gravity Main CCTV Inspection (<=15 Inches Diameter/Collectors) – Gravity mains
under 15 inches are inspected by in house staff using a CCTV camera and inspection
software. PACP scoring is used for consistency. Manholes are only visually inspected
during in-house CCTV. CCTV inspections for condition assessment purposes are done
every 5 years at a minimum. This information is recorded in the city’s CCTV inspection
software (GraniteNet) and used to make rehabilitation and replacement
recommendations for the CIP program. CCTV inspections are also used to check the
quality of the cleaning program. Sewer mains are selected for filming each month from
the mains cleaned the previous month and based on the last date filmed. Inspection
Tasks are created in Cartegraph under the direction of the Maintenance Planner and
exported monthly to the CCTV truck. As the inspections are completed in the CCTV
truck, they are uploaded each night to Cartegraph. The CCTV crew closes out the
inspection Task in Cartegraph and based on the information they enter, follow up Tasks
may be automatically created by Cartegraph for follow up work. Periodically, CCTV
inspections are scheduled for other reasons (root control follow up, locating laterals for a
contractor, post-rehabilitation filming). The process above is followed for these
inspections too. Sewer mains with known defects/root intrusion problems may be
inspected more frequently if warranted.
Gravity Main CCTV Inspection (>=15 Inches/Interceptors) – Interceptors (generally
mains with a diameter >=15 inches) are filmed every 5-7 years. This work is contracted
out. The contractor is tasked with inspecting the mains and the manholes using
NASSCO coding (PACP/MACP). The contractor or city staff will also inspect the
manholes from the top and record visual observations. The contractor will export a
NASSCO format database and provide it to the city as a deliverable. This allows the city

to import the inspections into the city’s CCTV inspection software, GraniteNet, where the
data can be used in the capital planning process. An inspection Task will be created in
Cartegraph but the inspection data may stay in GraniteNet. As the integration between
GraniteNet and the CMMS is new there is currently no process to upload the inspection
data into Cartegraph and the city will explore the feasibility of this process over the next
few years.
Root Control – Wastewater staff apply chemical root control to sewer mains and
manholes in problem areas. Salt injections have also been used around manholes and
the city is evaluating the effectiveness of this method to determine whether to continue
using it. The city has started a more formal root control program based on data from
cleaning and CCTV inspections. Once a main is identified as needing root control to be
applied a Task is created in Cartegraph and assigned to Collections staff. Roots that are
causing a blockage are always removed right away, but those that can be treated are
deferred. When Collections staff has finished their cleaning for the month, they apply root
control to the lines that have Tasks associated with them. Once root control chemical has
been applied the Maintenance Planner creates a follow up CCTV task and sends the
CCTV crew out to film the line again in 3 months. If it doesn’t look like the initial treatment
was effective, the cleaning crew is sent out to reapply the chemical. The main is
CCTV-ed again at 6 months to see if the root control has been successful. If it hasn’t
been successful the main is cleaned and put on a more frequent cleaning schedule. It is
also referred to Engineering as a candidate for lining or spot repair. If the chemical
application was successful and the roots have died off, the line will be monito red and root
control chemical applied as needed to keep the line clear of roots.
Inflow and Infiltration Program – The city makes an effort to conduct annual flow
monitoring in small areas of the city. Each year the city works with a contractor to identify
an area that can be monitored with 8-10 flow meters (the number is based on available
budget). The monitors are installed for a 6-week period when rain is likely. The contractor
analyzes the data and provides recommendations for follow up smoke testing. The city
will contract for smoke testing in the recommended areas if budget is available.
Lift Station Inspections – The city operates and maintains 11 lift stations as part of the
collections system. Wastewater Operators inspect the six larger stations five times per
week (M, W, F, Sa, Su). Larger stations are defined as lift stations that have the capacity
to pump over 1MGD (although they may not have reached this capacity yet). The five
smaller stations are inspected two times per week.
Lift Station Preventive Maintenance – Preventative maintenance schedules have been
developed for the equipment in the lift station initially based on manufacturer’s
recommendations. The schedules are evaluated regularly and adjusted based on
feedback about operating conditions. Air Pollution Control District permit requirements
may also dictate maintenance activities or schedules.
4.3 Training
The Wastewater Division has a comprehensive training program. In addition to the
training required under the General Order, staff are routinely trained on safety topics as
directed by the city’s safety program. All wastewater staff are required to maintain CWEA
certifications as outlined in their job descriptions, so staff also attend training on

The Wastewater Division stocks equipment necessary for day-to-day operations and
emergency response on city vehicles. Parts are maintained in the Utilities Department
warehouse and inventoried in the city’s CMMS. This inventory of equipment and parts
are replaced as needed.
The Wastewater Division maintains a list of critical parts for lift stations and for minor
repairs in the collections system. Major repairs/replacement are contracted out. All lift
stations are built with redundancy and have one extra pump that is not needed to pump
the total design volume and that can be rotated in if one of the other pumps goes down.
A spare pump is also stored at each lift station. Other critical parts, such as fuses and
impellers are kept in the Utilities warehouse or at the lift station site. The critical parts
lists are reviewed biannually to maintain accuracy and confirm the continued availability
of the listed components.

7 Sewer Pipe Blockage Control Program
7.1 Program Overview
The city’s FOG Control Program demonstrates the city’s pro-active approach to
management of the sanitary sewer system, and helps reduce the amount of FOG
discharges to the sanitary sewer system, by including:
• An implementation plan and schedule for a public education and outreach program
that promotes proper disposal of pipe-blocking substances;
• A plan and schedule for the disposal of pipe-blocking substances generated within
the sanitary sewer system service area. This may include a list of acceptable
disposal facilities and/or additional facilities needed to adequately dispose of
substances generated within a sanitary sewer system service area;
• The legal authority to prohibit discharges to the system and identify measures to
prevent spills and blockages;
• Requirements to install grease removal devices (such as traps or interceptors),
design standards for the removal devices, maintenance requirements, best
management practices (BMPs) requirements, recordkeeping and reporting
requirements;
• Authority to inspect grease producing facilities, enforcement authorities, and whether
the Enrollee has sufficient staff to inspect and enforce the FOG ordinance;
• An identification of sanitary sewer system sections subject to FOG blockages and
establishment of a cleaning schedule for each section; and
• Implementation of source control measures for all sources of FOG reaching the
sanitary sewer system for each section identified above.
7.1.1 Implementation Plan and Schedule for Public Outreach
The Wastewater Division works with the Communications Department to provide
information to the public about preventing pipe blockages. Carlsbad has a Clog
Prevention page on its website that provides information regarding the typical causes of
sewer backups and tips for preventing them. This is primarily geared towards residential
and non-restaurant commercial customers. The Clog Prevention page includes the
following causes of sewer backups along with tips to avoid clogs:
• FOG: Washing food, oil and grease down your drain and disposal can lead to
grease buildup that can clog sewer lines. Grease buildup that leads to property
damage, environmental problems, along with other health hazards. Home
garbage disposals do not keep grease out the plumbing system and detergents
pass grease down the line and cause problems in other areas.
• Tree and shrub roots: Invasion of tree and shrub roots into sewer pipes cause
nearly half of the city’s pipe overflows each year. Roots search for water and
nutrients and can enter pipes through small cracks. Once in the pipe, they can

Docusign Envelope ID: 21ECF657-6D61-484E-9F71-2A8FD743F3D7
Sewer System Management Plan 2025 SSMP Update
40 | FINAL – June 23, 2025
grow rapidly and cut off sewer flow, causing backups into the home or overflows
outside of the home.
• Flushable wipes: Disposable wipes, even flushable ones, can do a number on
sewer lines. Throw wipes and towelettes as well as dental floss, feminine
hygiene products and paper towels in the trash, and not in toilets. The city has
developed a video series, Wipes Clog Pipes, showing what can go wrong when
you flush flushable wipes.
• Face masks, gloves or other personal protective items: All of these items should
be disposed of in the trash, not toilets. These can create serious blockages in
home plumbing systems and the overall sewer system. The safest way to
dispose of masks and gloves is in a trash bag that can be sealed and disposed
of.
The city reinforces this message with social media campaigns throughout the year
reminding people what not to put down their sinks and toilets. These campaigns typically
occur around the November and December holidays. The Wastewater Division also
participates in three city events held during the year for the public and uses that
opportunity to promote the message of what to avoid putting into the sewer system.
These events are the Citizen’s Academy, held in the spring and the fall, and the Public
Safety Open House, held in the fall.
Additionally, the city has a commercial FOG program for food service establishments
(FSEs) (as defined by the city’s municipal code). This program includes an inspection
component where an inspector visits new restaurants and provides outreach materials,
including a poster for the kitchen. Letters are mailed annually to all FSEs reminding them
to properly dispose of FOG and to clean their grease control devices and sewer laterals.
Information about FOG requirements for food service operators can also be found on the
sewer page of the city’s website.
7.1.2 Plan and Schedule for Disposal of Pipe Blocking Substances
within the Service Area
The city provides all FSEs with a list of independent vendors who can provide collection
and disposal services in the service area. This list is provided as a courtesy and FSEs
are not required to use one of these vendors. FSEs contract directly with grease haulers
to collect grease from FSEs and to properly dispose of the grease. The city requires
grease to be disposed of properly and FSEs are required to keep all manifests, receipts
and invoices for all cleaning, maintenance, grease removal from pretreatment devices,
hauling and disposal of waste, and cleaning of pretreatment facilities, such as grease
traps, by facility employees or outside vendors.
Any FOG or other pipe blocking debris that is removed by staff during maintenance or
repair activities is disposed of properly at the EWA Treatment Plant.

7.1.3 Legal Authority to Prohibit Discharges and Identify Measures to
Prevent Spills and Blockages
No food service facility shall discharge or cause to be discharged any FOG to the sewer
system in concentrations that may result in separation from effluent and adherence to
sewer structures and appurtenances, accumulate and/or cause or contribute to
blockages in the sewer system or at the sewer system lateral which connects the food
service facility to the sewer system (CMC 13.06.010).
7.1.4 Grease Removal Devices Requirements and Standards
Requirements to Install Grease Removal Devices
The city’s requirements to install grease control devices are discussed in the following
sections of the City of Carlsbad, Municipal Code, Chapter 13 (Sewers):
• Section 13.06.040 FOG pretreatment required;
• Section 13.06.090 Grease interceptor requirements, and;
• Section 13.06.100 Grease trap requirements.
Design Standards for Grease Removal Devices
The city has a standard drawing for the grease interceptor. Utilities Wastewater Division
staff, or the inspection contractor, performs annual FOG inspections where grease
interceptor records are inspected to ensure that interceptors are routinely serviced to
minimize FOG discharges to the sewer system.
Best Management Practices Requirements
The maintenance requirements, BMP requirements, record keeping and reporting
requirements are found in the following sections of the municipal code:
• Section 13.06.130 Grease interceptor maintenance requirements;
• Section 13.06.030 Best management practices required;
Maintenance Requirements
• Section 13.06.130 Grease interceptor maintenance requirement
Record Keeping and Reporting Requirements
• Section 13.06.140 Monitoring and reporting conditions.
7.1.5 Authority to Inspect Grease Producing Facilities and Enforcement
City of Carlsbad Municipal Code Section 13.06.110 provides authority for the city to
inspect food service facilities and ensure that grease control devices are being properly
maintained, and that the facility is in compliance with the city’s FOG regulations. New
FSEs are inspected and provided with information about the city’s FOG requirements
and regulations, including BMPs and grease disposal. All FSEs are required to annually

provide proof that their grease control device is being maintained, that FOG is being
disposed of properly, and that their sewer lateral is being cleaned. FSEs that do not
provide that proof are subject to enforcement actions. The city can issue Notices of
Violation and Administrative Citations with fines to FSEs that are not complying with the
FOG regulations.
7.1.6 Identification of Sanitary Sewer System Section Subject to FOG
Blockages and Establishment of Maintenance Schedule
The city uses data from cleaning and CCTV activities to identify areas of the collection
system that are subject to a buildup of FOG. These sewer mains are put on a more
frequent cleaning schedule to prevent the buildup, and CCTV is used to verify that the
frequency is adequate. The city has not had a FOG-related spill in over 5 years.
7.1.7 Development and Implementation of Source Control Measures for
All Sources of FOG
The city’s wastewater division uses multiple strategies to address FOG:
• Sewer mains in areas with known grease accumulation are cleaned more
frequently, either quarterly or semi-annually.
• Data from CCTV inspections is routinely reviewed and is used to change
cleaning frequencies as needed due to FOG or other potential blockages.
• New FSEs or those that are remodeling are required to apply for a building
permit through the city’s Community Development department. The Building
department checks all plans for compliance with the Plumbing Code and the
Municipal Code regarding grease removal devices and is responsible for
inspecting the sites to ensure that the grease interceptors are installed.
• Some residents and commercial property owners (who do not meet the definition
of an FSE) discharge a significant amount of FOG into the sewer system. The
city is gathering information on those locations through CCTV and private lateral
spill reports and is planning to look at options for reducing the FOG. The intent is
to have a process in place to address non-FSE FOG by the end of 2027.

8.1.1 Evaluation of Sanitary Sewer System Assets and Condition
Assessment Strategy
The city takes a thoughtful, data-driven approach to collection system asset inspections
and condition assessments. The goal is to develop inspection schedules and perform
inspections in a programmatic manner. Currently, the bulk of the inspections and
condition assessments are performed on gravity sewer mains and manholes. An Asset
Management Master Plan was developed in 2019 that provides guidance for condition
assessments for manholes and mains and also established CIP program budgets for
regular collection system rehabilitation and replacement activities.
Gravity Mains – The strategy for gravity mains includes maintaining a schedule for the
inspections, performing the inspections, analyzing the data, fixing immediate issues and
providing a prioritized list of facility defects to the Engineering Division for rehabilitation or
replacement. All collector gravity mains are inspected every 5 years, with mains that
have known issues inspected more frequently if need. Interceptors are inspected every 5
to 7 years by a contractor. CCTV is the primary tool used for sewer main condition
assessments.
Staff can inspect approximately 20% of the collector sewer mains each year with current
resources. The city also maintains as-needed agreements with contractors that can be
used to supplement city resources if needed. Carlsbad’s sewer service area contains
three lagoons, several creeks and a significant amount of sensitive habitat, including a
couple of waterbodies with bacterial impairment. Additionally, there are many areas that
would incur a significant environmental and economic impact if spills were to occur,
especially during major events like golf tournaments, the annual marathon and 5K
events, the Village Faire and times when tourism is high. The city is also home to
Legoland. All of this factors into the city’s decision to maintain a 5-year inspection
program.
Five years is considered a high frequency in the industry but based on the data collected,
the success of spill avoidance by performing CCTV on this frequency, and the potential
impacts if spills occurred, the city has determined that an aggressive, proactive CCTV
scheduled is warranted.
The CCTV data is regularly reviewed and used to make changes to the preventive
maintenance program to improve its effectiveness. The observation data is input into a
capital planning tool, assigned risk scores, prioritized, and are referred to Engineering for
rehabilitation or replacement.
Manholes – Manholes for the collectors are visually inspected from the top during
cleaning activities and are assigned scores of 1 (like new) to 5 (failure is imminent). This
data is reviewed monthly. The manholes are also inspected from the invert during CCTV
although no scores are assigned. High scoring manholes are put on a list of candidates

for rehabilitation. The city is exploring using a 360 degree scanning tool for manholes
that score high during visual inspections to evaluate the effectiveness of the visual
inspections.
Lift Stations – Wastewater Operations staff inspect the lift stations 2-3 times a week
depending on station size to assess that the stations are operating properly and assist
with finding issues that could turn into bigger problems. Operations staff take care of
minor repairs/maintenances in house and contractors are used for specialized services
such as the monthly generator maintenance and electrical work. Rehabilitation and
replacement projects are handled by Engineering through the CIP process. Generator
replacements and electrical upgrades are scheduled for two lift stations in the next 3
years (Poinsettia LS and Chinquapin LS). The 2019 Asset Management Master Plan is
scheduled to be updated over the next 2 years and vertical assets will be included. The
city expects to develop condition assessment activities and schedules for lift station
assets and to use that information to recommend CIP budgets for these activities.
8.1.2 Inspection and Assessment Recordkeeping
CCTV inspection observations and videos are all maintained in GraniteNet. GraniteNet is
a cloud-based CCTV software enabling city staff to access from any computer in the city.
GraniteNet is also GIS-based, enabling results to be easily linked with the city’s GIS-
based CMMS (i.e., Cartegraph). Results from CCTV are easily accessed and viewed by
staff.
8.1.3 Assessing Assets Vulnerable to Climate Change
In 2023, the City of Carlsbad conducted a Climate Change Vulnerability Assessment to
evaluate and identify the potential impacts that climate changes pose for the city. The
biggest risks identified for wastewater infrastructure were from wildfires, flooding and sea
level rise. As part of the assessment, the city reviewed the locations of all wastewater
assets and identified several lift stations, as well as certain gravity mains and manholes,
situated in high-risk areas. To enhance system resilience, the city has equipped 9 of its
11 lift stations with on-site emergency generators and maintains 2 portable generators to
provide backup power to the remaining stations as needed. The city also has 3 back-up
bypass pumps. A portable 4” pump, a portable 6” pump, and a stationary 8” pump
(stationed at Poinsettia lift station as needed).
8.2 Capacity Assessment and Design Criteria
In 2019, the city completed a Sewer Master Plan (SMP) of their wastewater system,
which included flow monitoring and the development of a hydraulic model. This model
was used to perform hydraulic analyses to assess the performance of the existing
wastewater system under dry and wet conditions, evaluate the impact of future growth,
and recommend improvements that may be needed to provide the necessary capacity
under both existing and future conditions. The city is in the process of completing an
update to their SMP, which is scheduled to be completed by 2026.

2025 SSMP Update
FINAL – June 23, 2025 | 45
8.2.1 Procedures for Identifying and Addressing Hydraulic Deficiencies
and Capacity Limits
Dry-Weather Peak Flow Conditions that Cause or Contribute to Spill Events
Similar to the 2019 SMP, the 2025/26 SMP Update will analyze existing wastewater
flows from EWA flow meters, historical daily wastewater flows, and temporary flow
monitoring to characterize and quantify dry weather flows. Average Dry Weather Flows
(ADWFs) will be calculated using a combination of EWA permanent flow meter data
along with temporary flow meter data.
Flow meter data will also be used to develop diurnal curves, which are 24-hour unit
hydrographs that are applied to ADWF to represent flow fluctuations throughout a typical
day. Diurnal curves will be developed for weekday and weekend day conditions for the
tributary areas of each of the flow meter locations used to develop ADWF loading. The
use of diurnal curves when accounting for the wastewater generation of each contributor
allows for a more accurate representation of flow variations and accounts for the routing
of wastewater through the collection system on a temporal basis.
Appropriate Design Storm or Wet Weather Event Criteria
Wet weather flow updates in the city’s hydraulic model will be based on storm events
from 2020 and 2023 where EWA experienced increased flow into the treatment plant. In
addition, sewer generation rates and rainfall-derived inflow and infiltration (I/I) will be
reviewed and used to recalibrate the model for improved accuracy. The city has
continued monitoring through flow meters since the 2019 SMP, and the collected data
will be incorporated into the current modeling effort. This updated information will be
used to refine the hydraulic model and more accurately characterize both sewer
generation rates and I/I contributions.
Capacity of Key System Components
Available capacity of collection system components is evaluated in the SMP analysis
based on a comparison of modeled flow rates and capacity criteria for system
infrastructure, including sewer pump stations, force mains, and gravity mains. Key
system components conveying relatively large flow rates include large diameter sewer
mains, force mains and the 11 sewer lift stations.
In the SMP analysis, gravity main capacity is estimated by comparing modeled pipe
depth over diameter (d/D) under Peak Wet Weather Flow (PWWF) conditions with the
evaluation criteria of 0.75 d/D. If modeled ADWF d/D exceeds 0.5 or if PWWF d/D
exceeds 0.75 the pipe is considered to exceed capacity. Similarly, sewer pump station
capacity is estimated based on a comparison of modeled PWWF arriving at the pump
station versus the firm capacity of the pump station. Hydraulic modeling results are also
compared with flow monitoring results for key locations in the collection system.
The 2025/26 SMP, will evaluate the capacity of the collection system to convey projected
flow loading.

46 | FINAL – June 23, 2025
Major Sources Contributing to Peak Flows Associated with Sewer Spills
The city has not experienced sewer spills attributed to capacity issues. The primary
causes of reported spills have been related to roots and debris.
8.2.2 Capacity Assessment Considerations
Data from Existing Condition Assessments, Maintenance, and Other
Available Information
During capacity assessments, the city reviews data from sewer pipeline condition
assessments, system inspections, spill history, flow monitoring, and other available
information to support a comprehensive understanding of system performance. This
information is used to inform overall capacity evaluations and guide any necessary
adjustments or improvements to the collection system.
Capacity of Systems Subject to Flooding and Increased Infiltration and Inflow
Due to Larger and/or Higher-Intensity Storm Events As a Result of Climate
Change
The city’s 2025/26 SMP Update will utilize a 10-year design storm event that aligns with
a member agency design storm that shares sewer interceptor systems with the city so
the hydraulic analysis is correlated between the two systems. Historical high-flow events,
including storms from 2020 and 2023 that resulted in elevated flows to the EWA
treatment plant, will be reviewed and incorporated into the hydraulic model calibration.
These updated peak flow conditions will be used to refine the model and conduct a
comprehensive capacity analysis. The results will help identify existing capacity
constraints and areas with elevated I/I, especially those that may be exacerbated by
climate change-driven storm intensifications. Findings and recommended improvements
will be documented in the 2025/26 SMP Update to guide future mitigation and capital
planning efforts.
Sewer System Vulnerability to Erosive Forces in Canyon and Streams
The majority of the city’s sewer infrastructure is not located within canyons or stream
channels, minimizing its exposure to erosive forces. However, localized flooding remains
a concern, particularly in areas where specific manholes are known to become
submerged during storm events. One notable location is VC1, a pipeline segment within
the city’s limits but owned and maintained by the City of Vista, where erosion was
observed along Buena Creek in 2020. In response, the City of Vista installed revetment
along the creek bank to stabilize the area and mitigate further erosion impacts on the
sewer system
Necessary Redundancy in Pumping and Storage Capacities
The City of Carlsbad operates 11 lift stations, each equipped with a redundant backup
pump to maintain service during equipment failure or maintenance. In addition, three of
these stations currently have dual force mains to provide additional reliability, and the city
is exploring the addition of three more in the future. As part of the ongoing update to the
hydraulic model, the city is evaluating peak inflow conditions to confirm that each lift

FINAL – June 23, 2025 | 47
station can effectively manage incoming volumes through either installed pumping
capacity or available emergency storage. This planning effort supports system resilience
and operational continuity during high-flow or emergency scenarios.
8.3 Prioritization of Corrective Actions
In 2021, the city completed a prioritized package of pipeline rehabilitation projects,
guided by InfoAsset Planner and the risk-based analysis and decision logic
recommendations. A second group of pipeline segments was subsequently identified and
forwarded to the Engineering Division for further review and rehabilitation planning in
2023.
Corrective actions continue to be prioritized through a multifaceted approach that
combines defect data with coordination of planned development and infrastructure
projects. The city evaluates known pipe defects alongside upcoming development
activities to determine the most appropriate response, whether rehabilitation or full
replacement. This strategy accounts for both defect severity and asset -level risk to
identify and package high-priority projects efficiently. Cross-departmental coordination,
particularly with the Water Division and the Transportation Department, is essential to
aligning project schedules and minimizing community disruption. For example, when a
transportation project is planned, sewer improvements in the same corridor may be
advanced to reduce redundant construction impacts and optimize overall project delivery.
Hydraulic deficiencies within the collection system are prioritized based on both timing
(i.e., existing versus future conditions) and flow scenarios (i.e., average dry weather,
peak dry weather, and peak wet weather). Existing capacity constraints are given higher
priority than those projected to occur in the future. Likewise, issues occurring during
average dry weather are prioritized over those that arise during peak dry weather, which
are in turn prioritized over those identified only under peak wet weather conditions. This
tiered approach ensures that the most critical system deficiencies are addressed in a
timely and cost-effective manner.
8.4 Capital Improvement Plan
The General Order requires the capital improvement plan to include the following items:
• Project schedules including completion dates for all portions of the capital
improvement program;
• Internal and external project funding sources for each project; and
• Joint coordination between operation and maintenance staff, and Engineering
staff/consultants during planning, design, and construction of CIPs; and
Interagency coordination with other impacted utility agencies.
8.4.1 Capital Improvement Plan with Project Schedules and Completion
Dates
The city maintains a Capital Improvements Program Budget document posted on the
City of Carlsbad’s website at:
https://www.carlsbadca.gov/departments/finance/City-budget-18655

Sewer System Management Plan 2025 SSMP Update
48 | FINAL – June 23, 2025
The Capital Improvements Program Budget documents the City of Carlsbad’s 5-year
capital improvement program plan with adopted budget for the current fiscal year (i.e.,
Year 1) and projected budgets for each of the following 4 years (i.e., Years 2 through 5).
In addition to the 5-year capital improvement program plan, the city also has a 15-year
forecast that assists the city in establishing a budgeting plan that anticipates very large
expenditures. Following the completion of the 2025/26 SMP Update, the city will
reassess current CIP projects prior to construction to confirm that project designs align
with both current conditions and projected future system demands. If any modifications
are needed, the city will revise the designs accordingly before moving forward with
construction.
The Agua Hedionda and Buena Vista lift stations are jointly owned by the City of
Carlsbad and the City of Vista/Buena Sanitation District, with the City of Vista serving as
the majority owner for both facilities. These stations are operated and maintained by the
EWA. EWA manages these facilities under its R-CAMP, which outlines the capital assets
and long-term planning for co-owned infrastructure. The proposed CIP projects and
budgets for these stations are presented annually to the owner agencies. Once
approved, the City of Carlsbad’s share of the CIPs for these lift stations is rolled into the
city’s annual CIP budget. Capital improvements exceeding $50,000 are planned,
designed and constructed by the owner agencies and coordinated among the owner
agencies and EWA.
8.4.2 Internal and External Funding Sources for Each Project
All sewer system projects are funded by the City of Carlsbad’s Replacement Fund as
well as developer or connection fees. The 5-year CIP budget is based on project phase
for Strategic Plan and Critical Need projects. This means rather than budgeting for the
entire cost of a project well in advance of when the project is scheduled to begin, the City
Council will be asked to consider appropriating money phase by phase. Phases include
scoping (which includes feasibility studies and needs assessment), conceptual design
(which includes environmental permitting and up to 30% preliminary engineering/design
completion), final design (which includes 100% engineering/design completion and final
engineer’s estimate) and construction as shown in Figure 8-1.
For example, as part of the annual budget process, city staff will request appropriations
for a new project, starting with initial scoping. This typically involves early planning work
and a feasibility analysis. When that work is completed, staff will return to the City
Council to request appropriation for conceptual design. When that is done, staff will
return to the City Council to request funding for final design, and so on.
Once plans and specifications for a project have been prepared, a more accurate
engineer’s estimate for construction costs can be produced that considers the most up -
to-date market conditions. By requesting appropriation of construction funding at the time
staff request approval of plans and specifications and authorization to bid, the city can
ensure that the approved project budget will align with the most accurate and timely cost
estimates available. The 15-year forecast will assist the City Council with making
informed decisions regarding the city’s ability to fund current and future projects.
The city conducts a comprehensive cost-of-service study once every 3 years to evaluate
the actual cost of providing wastewater services to the community. These studies ensure

that rates are fair, equitable, and aligned with the financial needs of operating and
maintaining the City of Carlsbad’s water, wastewater, and recycled water systems. The
rate studies include estimates for the city’s share of costs for CIP projects for the
EWPCF, the Agua Hedionda lift station and the Buena Vista lift station, as well as the
city’s share of the expected operations costs for the treatment plant. Findings from the
study, along with any proposed rate adjustments, are presented to the public for review
and input. Rate increases may be recommended as a result of rising operational,
maintenance, and capital improvement costs necessary to sustain reliable service
delivery.
Figure 8-1. Project Funding Budget Cycle
8.4.3 Project Delivery Coordination and Interagency Coordination
The city’s Utilities Department leads the delivery of capital improvements projects and
coordinates closely with staff on any CIP projects involving or impacting the collection
system. The Utilities department also identifies any impacted agencies, utilities and
neighboring cities early in the project planning process and coordinates with agencies,
utilities and neighboring cities throughout the project delivery lifecycle to obtain permits,
determine utility location, etc.

9 Monitoring, Measurement, and Program
Modifications
The city has developed a leading edge performance management system to monitor and
measure the effectiveness of the SSMP program implementation and to perform data
analytics to diagnose the root causes of issues impacting SSMP program effectiveness.
The city uses this system to monitor the performance of the collection system on an on-
going basis through monthly performance management system reviews performed at the
operating unit level, and annually during Utilities business planning, goal setting and the
annual budget review.
9.1 Maintenance of Information to Prioritize SSMP
Activities
Table 9-1 lists the information systems the city uses to collect, store and analyze SSMP
program data. Key data collected by city staff includes:
• Pipe, manhole and pump station asset attribute data
• Pipe, manhole and pump station asset failure history
• Pipe, manhole and pump station maintenance schedule and work history
• Pipe, manhole and pump station asset inspection data
• Pipe, manhole and pump station asset remediation decisions
The data collected in these information systems provides the source data for the city’s
performance management system.

9.2 Monitoring of Implementation and Effectiveness of the
SSMP
The city actively monitors SSMP program effectiveness using a multi-layer performance
management framework that incorporates the types of performance measurement
described in Table 9-2. This multi-layered performance management system is linked to
the live information systems providing timely data analysis. The city spent several years
building and refining this system and it is proving to be an invaluable tool for assessing
SSMP program effectiveness, drilling down into the root causes of sewer overflows and
the process breakdowns that may be impacting the overall p erformance of the SSMP
program implementation.
Table 9-2. Multi-Layered Performance Management Framework
Measurement Type Measurement Description
Failure analysis The city reviews reported SSOs, prevented SSOs, and lift station equipment
failures. These events drive root cause analysis. Failure events are
visualized on charts to show monthly or seasonal changes and on maps to
show geographical trends.
Productivity analysis The city is tracking the unit cost of routine cleaning, frequency cleaning, and
routine filming to provide insight into work efficiency as well as insight into
potential work capacity issues that may be arising.
System flows conveyed The city compiles data from EWA reporting to track average flows from the
six EWA owners into the EWPCF. The city is also tracking the ratio of
gravity flows versus pumped flows and the ratio of the flow conveyed to
EWA from the city versus the overall flow.
System condition monitoring The city is closely monitoring the type and severity of material found during
cleaning activities; manhole condition ratings; and CCTV inspections surpassing condition threshold. This data is charted and mapped to support
root cause analysis drill downs. System condition monitoring is also used to
change preventive maintenance frequencies for sewer cleaning.
Production monitoring Production of key SSMP program activities are monitored including
preventive maintenance cleaning production and average daily footage;
preventive maintenance filming production and daily footage; ratio of
scheduled versus completed lift station preventive maintenance; the
number of scheduled lift station preventive maintenance work orders by
priority; and the number of incomplete lift station work orders. These are
visualized in various charts for analysis.
Field staff utilization tracking The city tracks the available time of collection system and lift stations
operators. This provides insights into why production may be impacted.
Unplanned work volume tracking The city is tracking the volume and types of service requests; the volume of
unscheduled lift station work orders; and the costs of unscheduled work
activities by lift station.
9.2.1 Course Correction Measures
To promote continuous improvement and maintain SSMP effectiveness, the city regularly
reviews the performance of its core program elements and makes adjustments as
needed. These course corrections are informed by operational findings, performance
data, and lessons learned from field experience. The city also evaluates long-term trends
to identify recurring issues, emerging problem areas, or opportunities for proactive
management. Modifications may include updates to maintenance schedules, targeted

infrastructure improvements, or revisions to standard operating procedures. This data-
driven approach ensures the SSMP remains aligned with the city’s goals.
9.3 Assessment of Preventative Maintenance Program
and Identification and Illustration of Spill Trends
The success of the preventive maintenance program is evaluated monthly using both
leading and lagging indicators built into the performance management system. Lagging
indicators include analysis of failures such as SSOs and private lateral sewage
discharges as well as potential failures such as blockages and lift station alarms. Leading
indicators include productivity analysis, production monitoring, system condition
monitoring and unplanned work volume tracking. The city works towards maximizing
planned work and minimizing failures. Each failure or potential failure is monitored to
determine if a trend is forming. Based on the analysis, corrective actions may include
localized preventive maintenance program modifications (i.e., changes to a small number
of pipe segments), such as a change to maintenance method or frequency, or, if a trend
appears to be forming, a programmatic maintenance program change to address
problems impacting a geographical area or specific asset class. The city’s SSO rate has
averaged below 1 SSO per 100 miles of sewer pipelines since October 2015, which is
well below the regional average. This SSO rate is a strong indicator of the success of our
preventive maintenance program.
9.4 Approach to Program Modifications and Plan Updates
The majority of program updates driven by performance monitoring affect a small
number of assets with a change occurring at the asset level with the modification being a
maintenance method or frequency change. The city is continually optimizing the
maintenance program to perform inspection and maintenance activities at the right
frequencies, using efficient methods and tools, and balancing cost with benefit derived.
9.4.1 Monitoring and Audit-Driven Program Modifications
Every 6 years the SSMP document is formally updated. The update consists of:
• Reviewing the existing SSMP language and updating any outdated information.
This includes updates to staff positions, names and organizational lines of
authority that have changed, changes to system characteristics such as basin
areas, etc.
• Updates to reflect new goals identified by the City of Carlsbad or Public Works.
• Incorporation of the adopted and implemented recommendations from previous
SSMP program audits.
• Upon completion of the 6-year SSMP update, the SSMP is provided to City
Council with a request for approval. Upon acceptance by City Council, the
updated SSMP is certified in the State Water Board CIWQS database and made
publicly available on the city website.

10 SSMP Program Audits
The city uses the SSMP audit process to identify actions for improving how it manages,
operates, and maintains the collection system. This process identifies the tasks and
actions that are required to meet SSMP goals and defines and prioritizes them.
Resourcing and planning for delivery of the actions identified in the SSMP audit are
incorporated into division-level business plans as described in Element 9 Monitoring,
Measurement, and Program Modifications.
10.1 Schedule of Program Audits and Updates
The city monitors the performance of the collection system on an on-going basis through
monthly performance reviews performed at the operating unit level, and annually during
division level business planning and goal setting and the annual business plan review. It
also performs a formal audit of its SSMP every 3 years in accordance with General Order
requirements. Every 6 years, the city formally updates and recertifies the SSMP.
Table 10-1 shows the anticipated schedule for SSMP audits and updates for the next 6
years.

The city will conduct an internal audit of their SSMP every 3 years and focuses on the
effectiveness of the SSMP and the city’s compliance with the SSMP requirements of
Order No. WQ 2022-0103-DWQ. The audit will include, but may not be limited to, the
following:
• Any significant changes to components of the SSMP.
• Any significant changes to the referenced documents, incorporated as
attachments to the SSMP.
• SSMP implementation efforts over the past 3 years;
• A description of additions and improvements made to the sanitary sewer
collections system during the past 3 years;
• A description of the additions and improvements planned for the upcoming 3
years, with an estimated schedule for implementation.

• Strategies to correct deficiencies, if identified, will be developed by the
responsible city division.
10.3 SSMP Audit Report
The findings from the SSMP audit are documented in an audit report. The audit report
includes the following elements:
• Audit findings and recommended corrective actions;
• A statement that sewer system operators’ input on the audit findings has been
considered; and
• A proposed schedule to address identified deficiencies
Once the audit report is complete, a QC review of the audit report is performed, with a
focus on consistency and completeness. The final audit report is reviewed by the city’s
LRO before final acceptance. Audit reports and related materials are maintained in a
hard copy and an electronic document tracking and management system.
10.4 Audit Implementation and Tracking of Results
The SSMP program audit recommended corrective actions are incorporated into the
annual business plan review and budgeting process to provide the necessary resources
to implement audit corrective actions and recommendations. Through that process,
implementation progress is measured and reported on an ongoing basis to ensure timely
completion of corrective actions. Deficiencies in meeting the schedule are identified or
anticipated and mitigation measures developed and implemented to manage completion
of the corrective actions from the audit. Each subsequent audit update begins with a
review of the previous audit to determine if the corrective action remains relevant and, if
so, to reiterate the program deficiency and recommended corrective action in the current
SSMP audit report. As described in Element 9 Monitoring, Measurement, and Program
Modifications, identified program updates necessary to enhance SSMP effectiveness are
included as a part of the following year’s business plan process and/or the formal SSMP
program audit.

11 Communication Program
11.1 Procedures to Communicate with Public for Spills and
Discharges
In the event of a sewer spill, and when warranted by the spill volume and/or location, the
city communicates with the public by posting warning signs and barricades put in place
along the area of potential public exposures. The Spill Emergency Response Plan
includes the following protocol:
Public Notification – Signs will be posted and barricades put in place to keep
vehicles and pedestrians away from contact with spilled sewage. Posting signs is
for keeping the public out of a that is not immediately cleaned up. Utilities
Superintendent/supervisor – Wastewater or the Utilities Technical Services
Manager or designee will determine whether posting is required in consultation,
as needed, with the San Diego County Health Department. Additionally, the
Utilities Superintendent/supervisor – Wastewater or the Utilities Technical
Services Manager or designee will use their best judgement regarding
supplemental sign placement in order to protect the public and local environment.
Sign will not be removed until directed by San Diego County Health Department.
Additionally, when contact with the local media is deemed necessary, the
Communications Department or their designee will provide the media with all relevant
information.
11.2 Procedures for General Communication with Public on
Development, Implementation and Update of SSMP
The city communicates with the public on a continual basis through the city website and
City Council meetings, which are open to the public. The most recent SSMP update was
approved at a City Council meeting on July 22, 2025, providing the public with the
opportunity to review the SSMP, as part of the City Council meeting attachments, and to
comment on the SSMP at the City Council meeting.
The city website also provides a continual link for the public to download the SSMP at:
https://www.carlsbadca.gov/departments/utilities/sewer
The webpage also invites the public to send any comments on how the city is operating
and maintaining the sewer system to wastewater@carlsbadca.gov or to call at 442-339-
2722. These modes of communication can occur at any time during development and
implementation of the SSMP.
11.3 Procedures to Communicate with Agencies that
Connect to the System
The city jointly owns an interceptor sewer, two lift stations, and associated force mains
with the City of Vista. The interceptor sewer routes sewage approximately 7.5 miles
through these two lift stations and associated force mains to the EWPCF. Both jointly-

owned lift stations are operated and maintained by EWA under various MOUs and
agreements.
All flows from the city are conveyed to the EWPCF, owned by EWA, for treatment and
disposal. The Utilities Director participates in monthly Member Agency Meetings (MAMs)
hosted by EWA, which is owned by six public agencies governed by a Joint Powers
Agreement. Under this agreement, owners share in the operational and management
costs of EWA. The six owners are:
• City of Carlsbad,
• City of Vista,
• City of Encinitas,
• Vallecitos Water District,
• Buena Sanitation District, and
• Leucadia Wastewater District.
The City of Carlsbad Utilities Director attends monthly MAMs hosted by EWA to discuss
and resolve issues impacting all parties. The MAM is primarily focused on issues related
to the Water Pollution Control Facility, yet can be utilized as a forum to discuss sewer
system issues and WDR compliance if necessary. In ad dition to these monthly meetings,
EWA coordinates annual budget planning meetings with member agencies, during which
EWA presents its projected costs for both the treatment plant and remote facilities. The
city uses this information to plan and budget for its share of operating expenses. The city
of Carlsbad Wastewater Supervisor also maintains regular communication with their
counterparts at the various member agencies and periodically coordinates joint trainings
on a range of operational and compliance topics such as spill response trainings. This
forum provides direct access to the various collection system managers of nearby
agencies when needed.
Through these mechanisms, the city is able to communicate with both the public on an
on-going basis as well as with collection system managers of nearby agencies when
needed to address issues impacting the city’s sewer system.

1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For
the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes,
valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other
pertinent infrastructure, upstream of a wastewater treatment plant headworks. A
sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary
piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion
structures.
Sewage is untreated or partially treated domestic, municipal, commercial and/or
industrial waste (including sewage sludge), and any mixture of these wastes with inflow
or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.
Sewage contains high levels of suspended solids, non-digested organic waste,
pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic
compounds, oils, grease, pharmaceuticals, and other harmful pollutants.
For the purpose of this General Order, a spill is a discharge of sewage from any portion
of a sanitary sewer system due to a sanitary sewer system overflow, operational failure,
and/or infrastructure failure. Sewage and its associated wastewater spilled from a
sanitary sewer system may threaten public health, beneficial uses of waters of the
State, and the environment.
This General Order serves as statewide waste discharge requirements and supersedes
the previous State Water Resources Control Board (State Water Board)
Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of
this General Order are enforceable by the State Water Board and Regional Water
Quality Control Boards (Regional Water Boards). Through this General Order, the State
Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the
State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping
requirements in this General Order that implement the federal Clean Water Act, the
California Water Code (Water Code), water quality control plans (including Regional
Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills;
• Eliminate discharges of sewage to waters of the State through effective
implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance
improvements; and
• Report noncompliance with this General Order per reporting requirements.

An Enrollee is a public, private, or other non-governmental entity that has obtained
approval for regulatory coverage under this General Order, including:
• A state agency, municipality, special district, or other public entity that owns and/or
operates one or more sanitary sewer systems:
o greater than one (1) mile in length (each individual sanitary sewer system);
o one (1) mile or less in length where the State Water Board or a Regional Water
Board requires regulatory coverage under this Order; or
• A federal agency, private company, or other non-governmental entity that owns
and/or operates a sanitary sewer system of any size where the State Water Board or
a Regional Water Board requires regulatory coverage under this Order in response
to a history of spills, proximity to surface water, or other factors supporting regulatory
coverage.
For the purpose of this Order, a sanitary sewer system includes only systems owned
and/or operated by the Enrollee.
2. REGULATORY COVERAGE AND APPLICATION REQUIREMENTS
2.1. Requirements for Continuation of Existing Regulatory Coverage
To continue regulatory coverage from previous Order 2006-0003-DWQ under this
General Order, within the 60-days-prior-to the Effective Date of this General Order,
the Legally Responsible Official of an existing Enrollee shall electronically certify the
Continuation of Existing Regulatory Coverage form in the online California Integrated
Water Quality System (CIWQS) Sanitary Sewer System Database. The Legally
Responsible Official will receive an automated CIWQS-issued Notice of Applicability
email, confirming continuation of regulatory coverage under this General Order. All
regulatory coverage under previous Order 2006-0003-DWQ will cease on the Effective
Date of this Order.

and after the ownership transfer date.
The Deputy Director will consider approval of the written request. If approved, the
Deputy Director will issue a Notice of Applicability letter which serves as an approved
transfer of regulatory coverage to the new Enrollee.
3. FINDINGS
3.1. Legal Authorities
3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical,
and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water
Code authorizes the State Water Board to implement the Clean Water Act in the State
and to protect the quality of all waters of the State (Water Code sections 13000 and
13160).
3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined
in Water Code section 13050(d) that could affect the quality of waters of the State and is
subject to regulation by waste discharge requirements issued pursuant to Water Code
section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations.
A discharge of sewage may pollute and alter the quality of the waters of the State to a
degree that unreasonably affects the beneficial uses of the receiving water body or
facilities that serve those beneficial uses (Water Code section 13050(l)(1)).

3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting
Water Code sections 13267 and 13383 authorize the Regional Water Boards and the
State Water Board to establish monitoring, inspection, entry, reporting, and
recordkeeping requirements. Water Code section 13267(b), authorizes the Regional
Water Boards to “require any person who has discharged, discharges, or is suspected
of having discharged or discharging, or who proposes to discharge waste within its
region… or is suspected of having discharged or discharging, or who proposes to
discharge, waste outside of its region that could affect the quality of water within its
region shall furnish, under penalty of perjury, technical or monitoring reports which the
regional board requires…In requiring those reports, the regional board shall provide the
person with a written explanation with regard to the need for the reports and shall
identify the evidence that supports requiring that person to provide the reports.” Water
Code section 13267(f) authorizes the State Water Board to require this information if it
consults with the Regional Water Boards and determines that it will not duplicate the
efforts of the Regional Water Boards. The State Water Board has consulted with the
Regional Water Boards and made this determination.
The technical and monitoring reports required by this General Order and Attachment E
(Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to
evaluate and ensure compliance with this General Order. The effort to develop required
technical reports will vary depending on the system size and complexity and the needs
of the specific technical report. The burden and cost of these reports are reasonable
and consistent with the interest of the state in protecting water quality, which is the
primary purpose of requiring the reports.
Water Code section 13383(a) authorizes the Water Boards to “establish monitoring,
inspection, entry, reporting, and recordkeeping requirements… for any person who
discharges, or proposes to discharge, to navigable waters, any person who introduces
pollutants into a publicly owned treatment works, any person who owns or operates, or
proposes to own or operate, a publicly owned treatment works or other treatment works
treating domestic sewage, or any person who uses or disposes, or proposes to use or
dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the
regional boards may require any person subject to this section to establish and maintain
monitoring equipment or methods, including, where appropriate, biological monitoring
methods, sample effluent as prescribed, and provide other information as may be
reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section
5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private
Sanitary Sewer Systems) of this General Order is authorized by Water Code section
13225(c) and encouraged by the State Water Board, wherein a local agency may
investigate and report on any technical factors involved in water quality control provided
the burden including costs of such reports bears a reasonable relationship to the need
for the report and the benefits to be obtained therefrom. The burden of reporting private
spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer
Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the
benefit of providing Regional Water Boards an opportunity to respond to these spills

when an Enrollee, which in many cases has a contractual relationship with the owner of
the private system, has knowledge of the spills.
3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements
Water Code section 13263(i) provides that the State Water Board may prescribe
general waste discharge requirements for a category of discharges if the State Water
Board finds or determines that:
• The discharges are produced by the same or similar operations;
• The discharges involve the same or similar types of waste;
• The discharges require the same or similar treatment standards; and
• The discharges are more appropriately regulated under general waste discharge
requirements than individual waste discharge requirements.
Since 2006, the State Water Board has been regulating over 1,100 publicly owned
sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste
Discharge Requirements) of this General Order). California also has a large unknown
number of unregulated privately owned sanitary sewer systems. All waste conveyed in
publicly owned and privately owned sanitary sewer systems (as defined in this General
Order) is comprised of untreated or partially treated domestic waste and/or industrial
waste. Generally, sanitary sewer systems are designed and operated to convey waste
by gravity or under pressure; system-specific design elements and system-specific
operations do not change the common nature of the waste, the common threat to public
health, or the common impacts on water quality. Spills of waste from a sanitary sewer
system prior to reaching the ultimate downstream treatment facility are unauthorized
and enforceable by the State Water Board and/or a Regional Water Board. Therefore,
spills from sanitary sewer systems are more appropriately regulated under general
waste discharge requirements.
As specified in Water Code sections 13263(a) and 13241, the implementation of
requirements set forth in this Order is for the reasonable protection of past, present, and
probable future beneficial uses of water and the prevention of nuisance. The
requirements implement the water quality control plans (Basin Plans) for each Regional
Water Board and take into account the environmental characteristics of sewer service
areas and hydrographic units within the state. Additionally, the State Water Board has
considered water quality conditions that could reasonably be achieved through the
coordinated control of all factors that affect water quality, costs associated with
compliance with these requirements, the need for developing housing within California,
and the need to protect sources of drinking water and other water supplies.
3.1.5. Previous Statewide General Waste Discharge Requirements
On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as
Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water
Code (commencing with section 13260) for inadvertent discharges to waters of the
State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated
sewage. Order 2006-0003-DWQ also required system-specific management, operation,
and maintenance of publicly owned sewer systems greater than one mile in length.

To decrease the impacts on human health and the environment caused by sewage
spills, the previous Order required enrollees to develop a rehabilitation and replacement
plan that identifies system deficiencies and prioritizes short-term and long-term
rehabilitation actions. The previous Order also required enrollees to:
1. Maintain information that can be used to establish and prioritize appropriate Sewer
System Management Plan activities; and
2. Implement a proactive approach to reduce spills.
The previous Order required Sewer System Management Plan elements for “the proper
and efficient management, operation, and maintenance of sanitary sewer systems,
while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ
with Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for
Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
Many enrollees of Order 2006-0003-DWQ have already implemented proactive
measures to reduce sewage spills. Other enrollees, however, still need technical
assistance and funding to improve sanitary sewer system operation and maintenance
for the reduction of sewage spills.
3.1.6. Existing Memorandum of Agreement with California Water Environment
Association
The California Water Environment Association is a nonprofit organization dedicated to
providing water industry certifications, training, and networking opportunities. The
Association’s Technical Certification Program provides accredited sanitary sewer
system operator certification for collection system operators and maintenance workers.
On February 10, 2016, the State Water Board entered into a collaborative agreement
with the Association titled Memorandum of Agreement Between the California State
Water Resources Control Board and the California Water Environment Association -
Training Regarding Requirements Set Forth in Statewide General Waste Discharge
Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative
training necessary for regulated sanitary sewer system personnel to operate and
maintain a well operating system and ensure full compliance with statewide sewer
system regulations.
On March 15, 2018, the State Water Board and the California Water Environment
Association amended the existing Memorandum of Agreement to include collaborative
outreach and expand training needs associated with further updates to Water Board
regulations for sanitary sewer systems. The State Water Board encourages further
Agreement updates as necessary to support improved sewer system operations and the
professionalism of collection system operators.

3.2. General
3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters,
within the boundaries of the state as defined in Water Code section 13050(e), and are
inclusive of waters of the United States.
3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses
Sewage contains high levels of suspended solids, pathogenic organisms, toxic
pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other
pollutants. Sewage spills may cause a public nuisance, particularly when sewage is
discharged to areas with high public exposure such as streets and surface waters used
for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.
More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving
waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting
surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal
parasites, and other microorganisms that can cause serious illness such as
gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis;
• Negatively impact ecological receptors and biota within surface waters; and
• Cause nuisance including odors, closure of beaches and recreational areas, and
property damage.
Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses
of surface water and groundwater. Potentially threatened beneficial uses include, but
are not limited to the following (with associated acronym representations as included in
statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2)
• Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN)

3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes
Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems
experience periodic failures resulting in discharges that may affect waters of the state.
There are many factors (including factors related to geology, design, construction
methods and materials, age of the system, population growth, and system operation
and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].
A proactive approach that requires Enrollees to ensure a system-wide operation,
maintenance, and management plan is in place will reduce the number and frequency
of SSOs within the state. This approach will in turn decrease the risk to human health
and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system
management using the best practices and technologies available to address major
causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and
o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from
identified system-specific environmental, and climate-change impacts, including but
not limited to:

o Sea level rise impacts including flooding, coastal erosion, seawater intrusion,
tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events;
o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but
not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration;
o Insufficient capacity due to population increase and/or new connections from
industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey
stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.
3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration
(exiting) of sewage from the system. Exfiltrated sewage that remains in the underground
infrastructure trench and/or the soil matrix, and that does not discharge into waters of
the State (surface water or groundwater) may not threaten beneficial uses.
Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of
the State. Exfiltrated sewage that discharges to groundwater may impact beneficial
uses of groundwater and pollute groundwater supply. Additionally, if in close proximity,
exfiltrated sewage may enter into a compromised underground drainage conveyance
system that discharges into a water of the United States, or into groundwater that is
hydrologically connected to (feeds into) a water of the United States, thus potentially
causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or
(3) surface water pollution.

3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration
Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering)
to sanitary sewer systems is preventable through proactive sewer system management
using the best practices and technologies available. The efficiency of the downstream
wastewater treatment processes is dependent on the performance of the sanitary sewer
system. When the structural integrity of a sanitary sewer system deteriorates, high
volumes of inflow and infiltration can enter the sewer system. High levels of inflow and
infiltration increase the hydraulic load on the downstream treatment plant, which can
reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause
illegal discharge of partially treated effluent, or in extreme situations make biological
treatment facilities inoperable (e.g., wash out the biological organisms that treat the
waste).
3.3. Water Quality Control Plans, Policies and Resolutions
The nine Regional Water Boards have adopted region-specific water quality control
plans (commonly referred to as Basin Plans) that designate beneficial uses, establish
water quality objectives, and contain implementation programs and policies to achieve
those objectives. The State Water Board has adopted statewide water quality control
plans, policies and resolutions establishing statewide water quality objectives,
implementation programs and initiatives.
3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled
Statement of Policy with Respect to Maintaining High Quality of Waters in California,
which incorporates the federal antidegradation policy. Resolution 68-16 requires that
existing water quality be maintained unless degradation is justified based on specific
findings.
The continued prohibition of sewage discharges from sanitary sewer systems into
waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary
sewers to waters of the State is prohibited by this Order. Therefore, this Order does not
allow degradation of waters of the State. In addition, this Order: (1) further expands the
existing prohibition of sewage discharges to include waters of the State, in addition to
waters of the United States as provided in previous Order 2006-0003-DWQ, and
(2) enhances the ability for Water Board enforcement of violations of the established
prohibitions.
3.3.2. State Water Board Sources of Drinking Water Policy
On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on
February 1, 2006), titled Sources of Drinking Water, establishing state policy that all
waters of the State, with certain exceptions, are suitable or potentially suitable for
municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled
Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of

value and directing Water Board programs to implement requirements to support safe
drinking water for all Californians.
On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled
Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening
Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among
other actions, through Resolution 2021-0050, the State Water Board, in summary as
corresponding to this General Order, reaffirms its commitment to its Human Right to
Water resolution, upholding that every human being in California deserves safe, clean,
affordable, and accessible water for human consumption, cooking, and sanitation
purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including
communities disproportionately burdened by wastes discharge of waste to land and
surface water;
• Restore impaired surface waterbodies and degraded aquifers; and
• Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding
implementation of its Climate Change Resolution to address the disproportionate effects
of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of
color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation;
• Sustainable management and protection of local groundwater resources;
• Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the
Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a
Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment,
supporting the equitable access to sanitation for all Californians and implementation of
Resolutions 2016-0010 and 2021-0050.
This General Order supports the State Water Board priority in collecting a
comprehensive set of data for California’s wastewater systems, including sanitary sewer
systems. Data reported per the requirements of this Order will be used with data from
other Water Boards’ programs, to further develop criteria and create a statewide risk

Implement Strategic Actions to Improve Data Accessibility and Associated Innovation,
directing regulatory programs to assure all monitoring and reporting requirements
support the State Water Boards’ Open Data Initiative.
3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled
Comprehensive Response to Climate Change, requiring a proactive response to climate
change in all California Water Board actions, with the intent to embed climate change
consideration into all programs and activities.
3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements
that is exempt from the California Environmental Quality Act (Public Resources Code
section 21000 et seq.) because it is an action taken by a regulatory agency to assure
the protection of the environment and the regulatory process involves procedures for
protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the
action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14,
section 15301, to the extent that it applies to existing sanitary sewer collection systems
that constitute “existing facilities” as that term is used in sections 15301 and 15302, to
the extent that it results in the repair or replacement of existing systems involving
negligible or no expansion of capacity.
3.5. State Water Board Funding Assistance for Compliance with Water Board Water
Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation
of the State Water Board financial assistance programs, per Board-adopted funding
policies. Among other funding areas, the Division administers loan and grant funding for
