SECTION 2
PROJECT CONCERNS AND OBJECTIVES
This section presents Brown and Caldwell's understaading of the requirements
for conduct of a satellite sewage treatment plant feasibility study for northeastern
Carlsbad. Our understanding of the City's needs is based upon a revim of existing
reports 8 conversations with the city's staff, a visit to the study area and our pre-
vious work for Carlsbad and the surrounding region. This basic understanding led
to the identification of certain concerns and objectives which we perceive to be of
utmost importance for the development of our approach to this project, An ovenrfew
of the existing situation, along with the project concerns and objectives are dis-
cussed below .
Overview
Because of the lack of available treatment capacity in the Encina WPCF, the
City of Carlsbad has imposed a sewer connection moratorium on new residential and
industrial development within the City. A proposed development in northeast Carlsbad.
Lake Calavera Hills 8 is proposing to construct an on-site secondary eeatment facility
as an alternate to the City's system. This proposal prompted the City'io investigate
the concept of utilizing satellite treatment plants to serve outlying areas, where the
potential for wastewater reclamation exists Based on the recent report "Overview of
Wastewater Reclamation Oppoktunities" and input from the City's staff, the City
Council has tentatively accepted the satellite plant concept. However, the City has
recognized that satellite treatment plants should be planned in conformance with
individual drainage basins or combinations thereof, and not for each new develop- ment or a portfon of users wfthin each new development. L
Since the Lake Calavera Hills development project Is a pressing issue with
sewage treatment and disposal being the major obstacle toward appmml of its master
plan, the City has decided to apply the "satellite plant concept'' to planning this
drainage basin. The feasibility study €or this drainage basin is necessary to anaIyze
the technical, environmental and financial considerations for proper wastewater man-
agement. Based on our knowledge of the requirements for such a feasibility study
and a basic analysis of the issues at hand, we have established the following primary.
concerns and objectives.
-Project Concerns .
Following is a brief discussion of the major concerns which have compelled the
City to implement this feasibility study:

e
Capacity limitations at the Encina WPCF have required that
the City of Carlsbad impose a sewer connection moratorium,
thereby restricting new' development
The water supply for the study area is principally Colorado River water obtained from the Metropolitan Water District through the
San Diego County Water Authority. Renegotiations of power
contracts in 1983 and the expected passage of more stringent
water treatment requirements will severely impact the price of
imported water.
The satellite treatment plant proposed by the Lake Calavera Hill5
developer does not meet the potential future needs of the entire
drainage %sin.
Establishment of a satellite treatment plant for the Lake Cdlavera
Hills drainage basin may set a precedent for other undeveloped
portions of the City of Carlsbad, This precedent couLd greatly
impact the future growth in the City,
Future wastewater facilities planning for the study area must meet
the criteria established by the Regional Water Quality Control Board
and must also consider the potential for wastewater reclamation. -
Specific location of the satellite treatment facility for the study area
Is an important factor. The facility should be located to optimize
capital and operation costs for conveyance and reclamation,
When development Rxceeds a certain level, groundwater disposal and
reclamation will not provide for disposal of &I wastewater during the wet weather periods. Provisions for adequate storage and conveyance
to the Encina Wastewater outfall during these periods will be an impor-
tant aspect of the project,
The City will have the'fiscal responsibility of operating and main-
taining the proposed Lake Calavera Hills sewage treatment plant and
other facilities. Therefore, the recommended method of treatment
technology will mintmize the economic and manpower impact on the
city,

SECTION 3
STUDY APPROACH
In this section, we present the details of our approach to the wastewater
facilities planning study for the northeast Carlsbad area. Our proposed scope
of work, budget estimate and time schedule are based on the City's Request for
Proposal and our understanding of the important concerns and objectives, which
were outlined in Section 2 of this proposal.
Methodolosv
Brown and Caldwell's planning approach is generally issue oriented. We
find that problems to be solved and issues related to their potential solution(s)
must be clearly identified. Issues of local concern can then be addressed in the
development and subsequent evaluation of alternatives and their impact . During
the initial phase, available data and information affecting wastewater management
in the study area will be reviewed and evaluated. Input from knowledgeable
individuals and organizations' will also be sought. Our technical staff will,
during the development phase, fully explore the possible options available to
solve the identified problems and meet the objectives of the project. Close coor-
dination between study team members, the City and other affected agencies must
be maintained throughout the phase through a strong project management effort.
Based on the information developed and on the identified constraints, project
alternatives will be screened and evaluated for their feasibility. Finally, recom-
mendations which best meet the technical, economical and environmental con-
straints of the City and service area will be developed.
Study Tasks
The primary goal of this project is to determine the feasibility of establishing
satellite treatment in northeast Carlsbad capable'of meeting the im'mediate-and
future needs of the area. Because much of the physical data has been assembled in
previous reports and this is not a Clean Water Grant project, only those items which
serve to establish the basis for this determination will be addressed.
For convenience in monitoring the work, the study will be divided into several
tasks and subtasks. Each task will generally address a specific phase of the
project, thus enabling the project manager and the City to effectively evaluate
progress toward the study's objectives. The following paragraphs describe in detail
the major tasks of the project.
.

- . -
3-2
TASK 0 - PROJECT MANAGEMENT
Project management includes those services necessary to provide management
and coordination between the City, the project team and other related agencies
throughout the course of the study. Project management tasks include:
. Establish budget amounts # project milestones, task completion
dates and study team assignments at the beginning of the study.
. Coordinate completion of the various tasks performed by project
personnel and monitor project status to ensure on-schedule ,
within-budget performance .
. Prepare for and attend regular meetings with the City's staff and
with other related # planned and regulatory agencies throughout
the study.
TASK 1 - FACILITIES PLANNING
This task will include the collection and analysis of data, evaluation of
alternatives and development of a recommended plan. Following is a discussion
of the major components of this task.
A. Study Area Characteristics. Evaluate and summarize availabl-e data on
the physical and socio-economic conditions and character of the study area which
directly affect wastewater management planning. Major aspects of this subtask
are as follows:
1.
2.
3.
Describe the study area (drainage basin) location and boundaries
and characterize its relationship to other agencies, service
areas, institutions and communities in the area
Evaluate the political, financial # physical and environmental
impacts of wastewater management within and around the study
area and develop the optimal service area.
Describe the existing and projected developments of the
service area, including the following characteristics:
a. present and future land use as represented on current
land use maps and master plans
b. economic activity and growth characteristics
Dc
3-3
c. population characteristics using areawide and local
agency projections or forecasts.
B . Water and Wastewater Characteristics . Evaluate and summarize
available data on water and wastewater characteristics , Major aspects of the
subtask are as follows:
1 . Evaluate existing water and wastewater quality characteristics
from availabkinf~rmatianA~ adjacent areas.
2. Evaluate unit water use and waste loadings from existing data
and develop unit criteria for design.
Project the future waste loads for the service area.
P
3.
C. Existins Wastewater Systems. Wastewater facilities planning for the
Lake Calavera Hills drainage basin must not conflict with region wide wastewater
management plans and facilities. Existing information will be reviewed to charac- terize the City of Carlsbad and regional facilities relative to the service area.
Specific items include:
1. Briefly describe the existing wastewater treatment and conveyance
facilities .
.
- 2. Examine the impacts of the satellite facility upon the regional
system.
3. Determine the technical and political impacts of providing capacity
in the Encina outfall during wet weather periods when groundwater
disposal and reclamation are not sufficient disposal methods
D. Waste Discharge and Treatment Requirements. Existing agencies with
jurisdiction over treatment disposal and reuse of wastewater include the State Water
Resources Control Board, San Diego Regional Water Quality Control Board, State
Department of Health and the Environmental Protection Agency, The policy and
criteria for each of these agencies relevant to wastewater treatment, disposal
and reuse in the service area will be evaluated. Specific tasks include the following:
1. Examine water quality objectives. Identify and develop
probable reuse and discharge requirements in consultation
Wth the San.Diego RWQCB and other affected agencies.
2. Review policy statements and quality criteria formulations
published by other agencies such as the Regional Water
Quality Control Board, the U. C . Agricultural Extension
Service and the EPA.
3-4 -_
3. Develop water quality requirements for each category of reuse,
including agricultural irrigation, landscape irrigation, stream
flow augmentation, wetlands enhancement and groundwater
recharge.
4. Propose treatment requirements for each category of disposal
and/or reuse.
5. Estimate the land requirements for a treatment and disposal
facility sized for ultimate capacity. Based on this estimate,
perform a Preliminary site evaluation study to determine potentia1
facility locations. (Note: this preliminary analysis will be
necessary in order to perform a preliminary cost effectiveness
analysis for wastewater reclamation distribution system alternatives.
Upon selection of a recommended treatment facility, the land
requirements and locations will be re-evaluated .
E. Wastewater Reclamation Potentiat. Because of rapidly rising costs of
imported water, it is necessary to fully evaluate the potential for use of reclaimed
water. The wastewater reclamation potential will impact the location and size of
facilities, treatment technology and capital and O&M costs of the project. The
specific items of this task include the following:
1. Conduct a preliminary market assessment to identify all pc;ltential
reclaimed water users in the study area. Survey techniques include:
a. Survey water use records to identify individual customers who
could potentially use reclaimed water.
b . Summarize use quantities and locate potential users
c. Review land use plans and other pertinent information to
identify potential future users.
2. Conduct field investigation of potential reuse sites to determine
their condition and any possible site constraints on reuse.
3. Identify all potentially feasible reclaimed wastewater distribution
alternatives. Perform cost -effectiveness screening , employing
linear programming to enable evaluation of many different sub-
alternatives . Further develop more feasible distribution alternatives.
4 . Perform detailed evaluation of most viable water reclamation alter-
natives, comparing cost-effectiveness of alternative water supplies ,
relative benefits of serving the various end users with reclaimed

water and institutional constraints affecting implementation.
Additional factors used in the screening will include location of
treatment facility, monetary cost, flexibility, environmental
impacts, energy demand , chemical requirements, public accept-
ance and priority of the reuse market(s) involved.
F. Project Alternatives Analysis. This task will consider the results of
preceding tasks and determine what alternative disposal, conveyance and/or
treatment configurations will best serve near term and future wastewater needs
in the study area. At this stage it will be important to evaluate the impacts of
projected population growth rates on the staging of facilities- Also, it must be
recognized that facilities for wastewater reclamation may not become cost effective
for several years. Therefore, alternative treatment schemes must be planned for
easy and economical capacity increases and process improvements when necessary.
Alternative layouts will be made, including sizing, conceptual design and estimated
costs. Specific items involved in this task include the following:
1. Develop criteria for preliminary design of ahernatbe wastewater
management systems Establish basis of cost estimates and
evaluation criteria.
2. Identify all potentially feasible wastewater treatment and disposal
schemes and conduct a preliminary evaluation of each. I
3. Perform initial cost-effectiveness screening of feasible alternatives
and select most viable alternative management systems. Review
selected most viable alternatives with the City's staff prior
to detailed evaluation and comparison. ,
.
4. Evaluate and compare the selected most viable alternative plans
in terms of the following:
a. conformance with identified constraints
b cost effectiveness
c. monetary cost
d . environmental impact
e. social impact
f. public acceptability
5. In addition, analyze the most viable alternative plans and sub-
alternatives in terms of:

SECTION 4
PROJECT MANAGEMENT
Successful completion of the proposed feasibility study for the City of
Carlsbad requires professional services which combine technical competence,
managerial experience, and team work in an efficient and thorough manner.
The talents and knowledge available from members of the project team and from
the City staff must be coordinated and used to their fullest extent to obtain
timely completion of the project and to minimize total cost to the City. Brown
and Caldwell is prepared to assemble a team of capable, experienced engineers
who are competent in the technical disciplines, necessary to successfully com-
plete the proposed study within the required time and with minimum budget
requirements.
A primary consideration of our proposed management plan is scheduled
communication between Brown and Caldweli and the City Department of Public
Works in order to keep the City advised of our progress. Every effort will be
made to translate the City’s needs and desires into project input and to keep the
City appraised of the project status.
Orsan izat ion
I.
I We propose to organize our study team along the lines .illustrated on the
accompanying chart. As shown, the work will be directed by the project manager
who is responsible to the City for overall direction and supervision of the work.
The project engineer will be responsible for day-to-day supervision and conduct
of project work. We believe that our organtzational concept has the following
advantages :

Excerpts from "Relevant Experience"
Section of Brown &. Caldwell's Proposal
Crescenta Val ley County Water District. In September, 1976, Brown 8,
Caldwell was retained to conduct a detailed facilities planning investi-
gation and develop a comprehensive plan for future wastewater management
for this unsewered community of 20,000 people. A detailed study of his-
torical water quality, coupled with a review of land use development
patterns, revealed that effluent from septic tanks was the primary cause
of nitrate contamination of the underlying groundwater basin. Brown 8,
Caldwell conducted a thorough investigation of all potentially feasible
alternative individual wastewater treatment and disposal systems, but
recommended a community-wide sewage collection system with an interceptor
down to the Los Angeles-Glendale Water Reclamation Plant.
This project is currently in the preliminary design phase. A unique as-
pect of the design is a "pressure sewer" analysis. Brown &. Caldwel I is
conducting a detailed study to determine whether the relatively new con-
cept of pressure sewers might be a cost-effective alternative to conven-
tional gravity sewers in certain sections of the District. Detailed de-
sign of the interceptor and collection system will commence in the near
future. Reference: Robert Argenio, General Manager, (213) 248-3925.
City of Flagstaff, Arizona. In 1977, Brown &. Caldwell was engaged by the
City of Flagstaff to formulate a master plan for wastewater management for
the city.
The city's two treatment plants were overloaded and treatment was inadequate.
Wastewater reclamation potential in the area was evaluated in detail due to
the high cost of water in the area. The study analyzed the optimum treat-
ment plant process, treatment plant capacity and treatment plant location.
A matrix was developed incorporating costs and other factors to determine
the most cost-effective project when considering both capital and operating
costs. The recommended project included a single IO mgd biofiltration sec-
ondary treatment plant at the site of the downstream plant, abandonment of
the second existing treatment plant, improvements to the collection system,
a new interceptor system and a wastewater reclamation system to reuse
treated effluent for golf course irrigation, landscape beautification and
industrial reuse. The total cost of the project is estimated to be approxi-
mately $20 million. For additional information, please contact John T.

wastewater reclamation feasibility study for the Walnut Valley Water District
to develop a facilities and implementation plan for marketing reclaimed
water from the Pomona Water Renovation Plant. A thorough market assessment
was conducted to determine price-demand relationships and to serve as the
basis for development of project alternatives. Potential end uses include:
landscape irrigation, industrial cooling, industrial process use, ground-
water recharge and oil field injection. A wastewater reuse advisory committee
Brown & Caldwell is currently completing a
made up of potential end users, local water utilities, the wastewater
agency and other interested individuals has been a key element in assist-
ing with gathering information, reporting project status, discussing con-
cerns and maintaining communication between the users, the District and
Brown & Ca I dwe I I. Fi rm user commitments and i nteragency agreements are
now being worked out. Following that, the recommended plan will be se-
lected, the implementation arrangements finalized and a final report com-
pleted by early June, 1978. Work on this project has greatly aided our
keeping abreast of those aspects of the grant program dealing with water
reclamation, and has resulted in our developing good working relationships
with those agencies that exert control over wastewater reuse. Reference:
