SUMMARY AND FINDINGS
There are three broad issues the community has to address in
it's future water plan. (1) What assets and liabilities
does the community currently have? (2) What facilities
will be needed for ultimate build out? (3) How will these
facilities be payed for?
It can be noted in the following Chapters the three main
transmission lines from the aqueduct to the service area may
not have adequate capacity at ultimate build out. In addition,
the service area will require a substantial amount of additional
ain transmission lines and storage capacity.
Squires Dam, which represents 93% of the community's storage,
is dependent upon the Health Department's approval. This
could become a problem should that approval be withdrawn.
It could result in the expenditure of funds for either a
downstream filter plant, or the construction of additional
storage.
Fortunately, the community has relatively little outstanding
debt for water facilities. From the information submitted
and estimates made, it appears approximately $U5 million
worth of new facilities will be necessary to complete the
community's ultimate water system.
The City has developed a Capital Improvements and replacement
program which identifies it's needs, costs, and funding
sources for the next 5 years. Costa Real is in the process
of developing a Capital Improvement and replacement program.
However, it has not proceeded far enough to identify all the
service area needs, costs, or funding sources. The following
is a summary of the facilities identified in the report.
COMBINED FACILITY NEEDS
Facilities Cost
1. Pipeline replacement $ 4,323,000,
2. Storage facilities 22,255,000,
3. Transmission lines 16,3U7,000.
U. Joint Operations Center 2,050,000,
,975,000,
ii
NOTE: The following facilities may have to be constructed
1. Additional covered storage or a filter plant if the
Health Department enforces it's covered storage policy.
2. Additional transmission capacity from the aqueduct if
the population and water demand develops as noted in
Chapter V.
3. Steel lines in certain areas corrode faster than normal.
The pipelines listed in Table 7 may have to be replaced
sooner than the normal 50 year life.
CAPITAL FACILITIES PLAN
In order to build these facilities/ it will be necessary for
the community to develop a plan which would include the
following elements.
1. A comprehensive community wide master water plan.
2. A facilities replacement program.
3. An immediate and long range Capital Improvement program.
k. A short and long term cash flow plan for all non-
operating revenues and expenses, i.e., Capital Improvement
funding.
iii
5. A five year cash program for system operations.
6. A revised water rate schedule that will encourage
conservation and assess cost in proportion to benefit
7. A comprehensive analysis of all non-operating charges
a.) Developer contributions.
b.) Connection fee.
c.) Account set-up fee.
8. Capital Improvement fund sources,
a.) Revenue sharing.
b.) Municipal Lease backs/Non Profit Corp.
c.) Assessment Districts.
d.) Revenue Bonds.
e. ) Grants.
f.) Short term loans.
g. ) Standby charges.

CHAPTER I.
PURPOSE
The purpose of the report Is to inventory the water facility
assets of the City of Carlsbad and Costa Real Water District
service areas.
In addition, identify those facilities necessary to provide
an adequate water supply to ultimate build out. This examination
would include those facilities that will have to be replaced,
either through deterioration or lack of adequate capacity.
It will be the initial step in preparing a skeleton Capital
Improvements and replacement program.
In order to implement such a program, a long-term financial
plan has to be developed to provide the necessary funding.
The future development of any community is dependent upon an
adequate water supply. A key ingredient in the provision of
this service is a planned and funded Capital program. The
foregoing items will be analyzed in an effort to provide an
insight as to the community's capability in fulfilling this
1.pi an.
1. "Community" is used as a collective term for the service areas
of both Costa Real and the City of Carlsbad.
1-1
CHAPTER II.
SCOPE OF WORK
1. Current inventory of major assets. This effort
will include inspection of existing records to identify
major assets, including such items as pump stations/ pipelines,
tanks, as well as system expansion capability. In other
words, those items that are considered an asset to any
enterprise type operation.
2. Facilities required to build out. This task would
involve a brief overview of the gross requirements, i.e.,
total water delivery capability, storage, etc. to provide
adequate water service for complete build out. It will not
address specific sizes, location, and exact cost.
3. Capital replacement program. A list of those
facilities that have to be replaced before the year 2000
will be identified, based upon existing records of each
agency.
U. Long-term financial program. This effort will
II-l
include a review of the Capital funding requirements as
determined by the Capital Improvements program. It will
also include a discussion on the various financing plans
available for funding both operations and Capital Improvements,
along with an observation as to the appropriateness of each
of those methods.
II-2
CHAPTER III.
BACKGROUND
The City of Carlsbad has recognized a key element in it's
future growth will depend upon an adequate water supply.
There are two major elements in utility planning.
1. A master water plan addressing the needs of the
proposed land use.
2. A suitable funding program.
The development of a master water plan, in large part, is
dependent upon land use planning. However, for the purposes
of analyzing the needs on a regional basis, gross water
demands can be estimated and incorporated in the program. A
major difficulty in developing a long range plan is determining
a suitable financing plan for constructing the facilities.
General Obligation Bonds, in the past, have proven to be one
of the most effective low cost means of financing Public
Works projects. Unfortunately, this vehicle is no longer
available. The development of an alternative and equitable
program has to take into consideration the nature of the
area, i.e., is it developed (replacement program) or is it
in a developing area (new capacity) and what is the ability
III-l
to pay for these improvements and who best pays for them -
the developer, land owner, water user???
The establishment of a master water plan and cost estimate
is a relatively straight forward effort. However, the major
policy decision is "who pays and when???". The success of
any program is dependent upon this decision. Each funding
plan has to be customized to meet the specific needs of the
community, as there is no one universal solution to a
Capital Improvement funding program.
OPERATION RELATIONSHIP
The Costa Real Municipal Water District encompasses a service
area of approximately 20,000 acres. The District provides
both retail and wholesale water service. Three major transmission
lines deliver treated water from the aqueduct system to the
community as noted in Plate 1. In addition, the District
provides regulating and emergency storage for the entire
community in its Squires Dam reservoir. The City, in turn,
receives its water through five metering stations from Costa
Real's system. Carlsbad pays Costa Real $16.00 an acre foot
for this service. This $16.00 is in addition to the cost of
the water.

CHAPTER IV.
METHODOLOGY
Since the information contained in this report is applicable
to the entire community, it was determined the Scope of Work
should be developed by the staff of both agencies. The data
used in this report was obtained during meetings with both
staffs, as well as individual interviews/ to insure accuracy
and completeness. It is the intention of this report to
provide the community with enough information to determine
their agency's ability to provide for it's future water
needs.
In addition, it will identify those areas that may need more
attention in order for the community to fulfill it's master
water plan. It will also provide an approximate estimate of
future costs for this program so adequate provision may be
made for the procurement of the necessary funds.

CHAPTER V.
FUTURE WATER AVAILABILITY
San Diego County Water Authority
With the construction of the Fifth Barrel, the San Diego
County Water Authority will have sufficient aqueduct capacity
to about the year 2000. Additional facilities will be
required beyond the year 2000.
The Metropolitan Water District of Southern California (MWD)
has a contract with the State of California for 2,500,000
acre feet of water, per year, which should meet the needs of
Southern California until the year 2020. However, MWD will
have to construct additional distribution facilities to the
San Diego area prior to the year 2000.
In order for the State to meet It's contractural commitment
to deliver this water, it will be necessary to construct
additional water conservation facilities. One of which is
the Peripheral Canal. A combination of facilities are
included in the construction program to guarantee the
delivery of water.
V-l
The Peripheral Canal, or any other conservation structures,
will take considerable time to construct. The Central
Arizona project coming online in 1985, will obviously reduce
the availability of water to MWD. In preparation of this
reduction, as well as a possible drought, MWD has instituted
their interruptible water plan which encourages member
agencies to store as much water as possible in surface
reservoirs or underground basins.
Further, MWD is now working with the local communities to
encourage and fund waste water reclamation programs to
supplement the water supply for Southern California. MWD
anticipates their interruptible pricing program, coupled
with waste water reclamation, would be sufficient to carry
the state through a drought period in 1985-86. However, the
State of California does have to complete it's water facilities
in order to guarantee an adequate supply of water to Southern
California to the year 2020.
The foregoing emphasizes the need for long-term storage,
water conservation and waste water reclamation, in order to
meet the community's long-term commitment for an adequate
water supply.

CHAPTER VI.
FUTURE WATER DEMAND
A report "Water System, Engineering Study - City of Carlsbad
1966" ' estimated the City would have a population of
40,000 by 1980 and the average daily per capita consumption
would decline from 280 gallons per day to 200 gallons per
capita per day. Therefore, the City's water demand would
increase from a "current 1966 usage of 3.3 million gallons
per day to 8 million gallons per day in 1980".
SANDAG Series V Population Study indicated the City of
Carlsbad's service area has a population of 19,000. Its
water consumption for 1980 was 5318 ACFT, or U.70 MGD. This
equates to 2U8 gpcd. This is relatively high because it
includes industrial, as well as domestic consumption. It
has been estimated the City's ultimate population will be
2.
160,000 people. This projection encompasses an area of
24,000 acres which is considered the entire planning area
for the City of Carlsbad. For the purposes of this study,
the 20,000 acre service area of the Costa Real Municipal
Water District was used. Assuming the population density

2. City of Carlsbad Interim Growth Management Program prepared by
Sedway/Cooke, May 1981.
VI-l
for ultimate build out is evenly distributed, this would
result in a service area population of 133,335 people.
It is anticipated the daily per capita demand may decrease
due to water conservation efforts, the use of reclaimed
water, and the increased cost of water. For the purposes of
this study, 160 gpcd has been selected as a reasonable
consumption. This is equivalent to a 21.33 MGD (33.1 cfs)
ultimate demand. Currently, the average annual demand on
the system is 11.9 MGD, or 18.U3 cfs.
WATER STORAGE
In planning the future needs of the community water supply
system, the obvious elements are the ability to transport a
sufficient amount of water from the aquaduct to the service
area and operational and emergency water storage. Currently,
the community can store approximately 3 weeks of average
annual demand. This amount of storage is a major safety
factor considering the possibility of a failure in the
aqueduct system. Assuming this policy continues in the
future, this would mean there would be an ultimate need of
1375 AF (acre feet) of storage.

Approximately 93 percent of this storage is in Squires Dam.
The Health Department requires all filtered domestic water
supplies be retained in covered storage. Squires Dam does
not meet this criteria and could be considered inadequate as
per Health Department standards. Currently the District is
under no order or demand to take the reservoir out of service.
PIPELINE CAPACITY
The service area is supplied by 3 transmission lines connected
to the San Diego County Water Authority aqueduct. They are
as fol1ows:
Faci1i ty Capaci ty
1. Tri-agencies pipeline consturcted
in 1979. 20 cfs
2. ID #1 pipeline, 1957. 25 cfs
3. South aqueduct line, 1981. Ik cfs
TOTAL 59 cfs delivery
capabi1i ty
These 3 pipelines are the basic imported supply to the service
area. In addition, the City of Carlsbad has rights to 3,^00
acre feet of ground water in the San Luis Rey River.
VI-U
Previously, it was estimated the ultimate population will
require an annual average flow of 21.33 MGD, or 33.1 cfs.
Transmission lines are normally designed to accommodate
maximum day (2.2 times annual average demand). In this
case, that would result in a maximum day demand of 46.9 MGD,
or 72.70 cfs. This would exceed the delivery capability of
the 3 existing lines. The current maximum day demand is
approximately 40.6 cfs.
The community is only 23 percent developed. This leaves
approximately 15,400 acres either undeveloped or in agricultural
production. As the community urbanizes (and there is every
indication it will), the total demand for water may decrease,
depending upon the intensity of development. As a general
rule, as an agricultural area urbanizes to a medium density,
total water demand does not change appreciably, however,
peak demand begins to reduce. One fortunate aspect of the
community's service area is that it can be served by gravity,
thus relieving it's dependence upon mechanical pumping
devices and energy. In the forthcoming years, energy will
become a major component in the cost of distributing water.

CHAPTER VIII.
FUTURE CAPITAL FACILITIES REQUIREMENTS
Replacement Program - City of Carlsbad
The City of Carlsbad has identified 2k different pipelines
that have to be replaced within the next five years. They
represent an estimated replacement cost of $823,000., based
on current prices. (Table 6). With construction costs
escalating at 1| per month, it can be seen the foregoing
estimate will increase quite rapidly.
Replacement Program - Costa Real Municipal Water District
Most of the District's water system is relatively new, thus
replacement of old pipelines is not much of a problem.
However, the Costa Real Municipal Water District has identified
four major steel waterlines that have to be replaced. (See
Table 7) If these pipelines were to be replaced at today's
cost and existing sizes, this would amount to an expenditure
of approximately $3.5 million. Since these pipelines represent
the major source of water for the community, it would be
prudent to set up a funding plan to replace these lines in
the event of an accelerated deterioration due to cathodic
corrosion problems.

this section will require replacement

be determined when land-use agencies
of our service area establish perma-
nent zoning and District can make a
final inventory of ultimate potable
water service needs.
3.2 miles of existing 20" diameter
steel pipe -- constructed in 1957-58;
this section will require replacement.
Pipe sizing will be evaluated after
City of Carlsbad - Water Department
and District determine ultimate water
requirements for City service area.
1.2 mileb of existing 20" diameter
steel pipe -- constructed in 1959;
this pipeline will require replacement
at such time its reasonable use has
been fulfilled. There is a possibility
its sizing may be changed in the event
the "Coastal Zone" land uses become
the permanent uses.
1.3 miles of existing 27" diameter
steel pipe -- constructed in 1961;
this pipeline will require replacement
at such time its reasonable use has
been fulfilled. In the meantime, the
pipeline will be paralleled by a
second supply line that will be a
part of the Squires Dam II expansion
program.
You can see from the listing that we have set out only four major pipe-
line projects. Our basic reason for this lies in the fact that the
multitude of other pipelines that are shown on our various approved
"Master Plans" and the many existing lines that will be replaced (steel
lines) in the future will all be accommodated at the "development"* •

stages of the various properties. Uniquely, our District constructed
its arterial water system in the late 1950's and early 1960's to
accommodate the vast "drylands" area of the District. With intensive
urbanization coming as a result of extending public sewer service to
our agricultural areas, the land form is'changing dramatically,
resulting in the extensive relocation and replacement of our pipe-
lines. In fact, in several instances, our District has delayed
pipeline projects in hopes the alignment of future streets and
highways are established formally so we will not be saddled with
expensive utilities relocation expenses.
With this initial level of inventorying of our Capital projects, we
shall be working in earnest to bring the entire program to a formal
level of comprehensive planning. We are now working on the District1:
last "Master Plan Study" and when the City of Carlsbad - Water
Department and the District decide on the ultimate needs of the City
service area, we will be ready tn complete the entire District-wide
Master Plan.
VIII-5
PUMPING
There is sufficient hydraulic grade (978*- 935) from the
aqueduct, so there is virtually no requirement for pumping
within the entire service area. This has obvious advantages
in that it eliminates energy costs, capital costs for pump
stations, as well as the maintenance problems that are
affiliated with any mechanical device. However, there are
numerous pressure reducing stations that require maintenance
and replacement.

This added to the existing storage of 6U7.2 ACFT results in
a total anticipated storage of 1,735.52 ACFT of water.
Should the Health Department decide to restrict or eliminate
Squires I, this would reduce ultimate storage capacity to
1,135.52 ACFT which is slightly less than the required 1375
ACFT (21 days of average annual storage). It can be noted
in the foregoing analysis that Squires I and Squires II are
a very integral part of the service area's storage needs.
Should the Health Department remove Squires I from active

service, this could accelerate the need for acquiring or
building additional storage to maintain the 3 week storage
capaci ty.
A study may be necessary to determine the economic practic-
ability of constructing a filter plant downstream of Squires
I if the Health Department determines that it is no longer
an acceptable filtered water storage reservoir.
TRANSMISSION LINES
Costa Real has approximately 75 miles of transmission and
distribution pipelines, ranging in diameter from 6" to 27".
The District is relatively undeveloped, thus more pipelines
will have to be constructed to provide service for ultimate
development. Since the District's Capital Improvement
program is very generalized, cost extimates were not included.
However, it can be estimated that approximately 50 miles of
12" through 18" water mains will be necessary to complete
the primary system for the ultimate development of the
service area. In order to accurately estimate the magnitude
of this particular element, it would be necessary to completely
study the area. This would ' include a master water plan for
the entire service area, outlining total water demand by
service zone as well as the necessary pipelines and storage
faci1i ties.
VIII-8
For the purpose of this study it will be assumed that an
equivalency of approximately 50 miles of 16" water!ine will
be needed for ultimate development. Based on current prices,
a 16" waterline will cost approximately $60./ft. for a total
cost of $15.8 million. This would include about $450,000.
for the proposed 1U" Elm Street line. In all probability,
the construction of these pipelines will be a combination of
developer/agency respons i bi1i ty.
As previously mentioned, one of the critical factors in
planning a capital funding program is trying to determine
specifically what is needed and when, as well as who is
going to pay for it. If the proposed storage were to be
constructed at today's dollars, this would result in an
expenditure of $21,630,000. Obviously, this is not going to
happen and it will be necessary to program the construction
of pipelines and storage taking into consideration inflation
and cash flow.
VIII-9
CITY OF CARLSBAD
The City of Carlsbad Utilities and Maintenance Dept. has
developed a 5 year Capital Improvement and Replacement
program. As noted in Appendix A, part of this program
includes an allocation of $2,050,000. for it's share of a
joint operations facility. In addition, a study completed
in 1979 "Master Plan for Public Water System for the Northeast
Quadrant Water Service Area", identified storage and pipeline
requirements for the City of Carlsbad. This amounts to one
half of the cost of the Tri-agencies pipeline storage for
$625,000., plus approximately $547,000. for additional
pi pelines.
The foregoing Chapters have identified major facilities that
will be necessary for the ultimate development of the community
water plan. They are summarized as follows:
