I. INTRODUCTION
Costa Real Municipal Water District (CRMWD) is the public water
service agency for a 2O,OOO-acre area bounded on the west by the
Pacific Ocean, to the north and south by the Buena Vista Lagoon
and the Batiquitos Lagoon, and to the east by the communities of
San Marcos and Olivenhain. Because of its geographical setting
with respect to the six communities that form the Encina Regional
Water Pollution Control Facilities, the CRMWD service area has
become the focal point of a large, potential marketplace for non-
potable water service to augment the public potable water supply
that is furnished by the CRMWD. As a matter of fact, extensive
pipeline facilities, several wa·stewater reclamation plants, pump-
ing stations, and other appurtenances have been constructed in
recent times and some of these facilities now have the capability
to produce and transport a suitable non-potable water supply for
immediate use. CRMWD has been active for many years in continu-
ally assessing the total water resources management program for
the entire service area.
In view of the current status of the many facilities that are now
available and that can be integrated into a functional network
of non-potable water service facilities, the authorization for
the overview of supply sources and the detailed engineering mas-
ter plan study is an appropriate step to be taken. The results
of such a study wi 11 guide us as we move into an era of rapidly
expanding opportunities to make available, to both current and
future CRMWD customers, an alternative water supply of adequate
quality and sufficient quantity to serve the supplementary needs
of our residential, commercial/industrial enterprises, and agri-
cultural pursuits •
The overview of potential sources of non-potable water supply is
important from the standpoint of long-range planning and inter-
agencies cooperation needed to develop a successful program. We
are fortunate indeed to have this rare opportunity to work in
coordination and cooperation with our several public agencies
with whom we share common goals to provide a new level of water
service consistent with efficiency, economy, and complete public
health safety.
There is presented .herewith our detailed report and to a very
large extent, this study reflects upon the development of overall
plans, construction, and implementation of an extensive public
potable water system that has served the CRMWD area since 1954.
Additionally, we are fortunate to have a. large area of informa-
tion and activity of the several wastewater reclamation -sewerage
agencies who have been working for many years towards the goal
of wastewater reclamation and reuse.
We acknowledge the generous assistance and cooperation of all
the public agencies who currently operate the various wastewater
treatment and reclamation facilities in and around the CRMWD

service area. These agencies constitute our initial group of
potential producers of non-potable water and ar-e the owners of
the extensive pipeline facilities which traverse· the various
sectors of our CRMWD. This pipeline network can be readily

I I. SCOPE AND PROCESS OF STUDY
Thi s study program i s di rec t e d pr i ma r i l y to the re ta i l s er vi c e
area of the CRMWD, with the concepts set forth herein for the City
of Carlsbad water service area being intended as recommendations
for consideration by that retail water service agency. The City
of Carlsbad functions as a sub-agency of CRMWD in terms of CRMWD's
role as the supplier of potable water to Carlsbad, and CRMWD's
position as the member agency of the San Diego County Water
Authority. Membership in the San Diego County Wat·er Authority
is a requirement for applying for possible financial aid by the
Metropolitan Water District's Local Projects Program in the
development of non-potable water resources.
Exhibit ''A" of this report, entitled "Master Plan for Public Non-
Potable Water System", delineates in detail the entire study area •
The goal of this master plan study is to adequately identify the
utilization of all of the existing non-potable water service fa-
cilities that have already been constructed within the boundaries
of the CRMWD service area and to identify those new facilities
that are appropriate to commence the initial levels of non-potable
water service within the CRMWD. The fundamental and basic theme
of this master plan is the simple fact that non-potable water
service should be made available on an equivalent basis with
non-potable water from the following standpoints:
* -*
*
Availability
Quantity
Service Characteri sties
In effect there should be virtually no difference to the CRMWD
customer in using the non-potable as opposed to the potable supply.
Inasmuch as the development of a public water system entai 1 s basic
design, the entire study area is analyzed from the standpoint of
topography, starting with the area along the Pacific Ocean and
moving back inland to lower foothill elevations of 500-600 feet.
Additionally, the proposed service area has two principal water-
sheds, namely the Agua Hedionda Creek (Agua Hedionda Lagoon) and
the San Marcos Creek (Batiquitos Lagoon) areas. The Buena Vista
Creek area to the north and the smal 1, centrally located Canyon de
las Encinas drainage basin comprise the remainder of the service
area.
As an emerging program, a careful assessment of the potential of
the marketplace for non-potable water service is necessary. Be-
cause there is a direct rel at i onshi p between non-potable water
usage and land-use planning/development concepts, projections of
a practical system must take into account the substantial expenses
for a dual water system and the various contractual considerations
such as quality, quantity, and pricing •

The basic engineering design of a non-potable water system
should be tied into the existing arterial network which is a
result of the new reclamation facilities that have Tecently been
constructed, and those that are proposed in the near term. Addi-
tionally, attention must be directed to all of the special design
features necessary for successful operation of a non-potable
water system intended for i rri gat ion as well as the management
of the non-potable water system with regard to the public health
and safety. In other words, the introduction of a water supply
of this character represents a formidable regulating task
regarding cross-connection control, and potential ·unauthorized
uses. In the actual development of the entire arterial master
plan, it is proposed to fully utilize all the existing facili-
ties, together with proposed pipeline facilities that would be
constructed in order to insure service reliability that would
be effected by inter-ties between all systems. The study program
would also identify the process by which a fully integrated
non-potable water system utilizing a number of separate sources
would be operated on an optimum basis to gain the greatest
amount of efficient water usage •
We have al ready commented upon the fact that this study repre-
sents an "implementation phase" of the several facilities con-
structed by neighboring wastewater reclamation agencies. Accord-
ingly, our study program has drawn heavily from the engineering,
environmental and master planning reports that have been previ-
ously commissioned. These reports are listed in the Bibliography
of this report. In particular, we stress the fact that this
master plan represents a functional updating and refinement of
the City of Carlsbad -Wastewater Reclamation Master Plan Study
which focuses upon a major portion of the service area of CRMWD •

I I I. HISTORY AND BACKGROUND WATER RESOURCES PLANNING FOR NON-
POTABLE WATER
The or191 n of the CRMWD in 1954 goes back to a time when the
local community water supply was becoming scarce in terms of
quantity, and the deteriorating quality was fast precipitating
the destruction of the local agricultural pursuits. The intro-
duction of imported water, first from the Colorado River and in
more recent times northern California water, spurred us to the
high 1 evel of community development which we now err joy, as well
as aiding the vast agricultural enterprises within our service
area. CRMWD, along with all of Southern California, depends
heavily upon the imported supp"ly and recognizes the importance
of moving towards a mode of water conservation. The inventory
and potential reassessment of the local supplies is necessary
so that in the future, we may continue to enjoy the good fortune
of an ample water supply, at an affordable cost •
An earlier milestone of this philosophy was during the early
1970's when a large petroleum refinery was proposed in the CRMWD
service area. There was a projection of some 3.0 million gallons
per day of water (mgd) required for the refinery. After a review
of extensive engineering reports, the CRMWD Board of Di rectors
decided that a total of 1.5 mgd of fresh water would be provided
to the refinery and that the remainder would have to come from
the reclamation and recycling of wastewater originating in the
San Marcos County Water District. Although that project never
moved forward beyond-the planning stages, the reel aimed water
policy position of the CRMWD became firmly established. Simply
stated, within certain limits and certain areas, the integrated
concept of water resources utilization would include local,
imported, and wastewater supplies.
During the middle 1970's, Southern California experienced the
hardships and difficulties of the long-term and state-wide
drought. During that time, the CRMWD launched an aggressive
water conservation program, and enunciated a basic policy posi-
tion that there would be, in time, a viable water reclamation
program utilizing our long neglected local supplies. This
policy would offer CRMWD customers a secondary or "non-potable"
water supply •
At this point, it is appropriate to set forth some specific
definitions for the purpose of this study report:
1, Non-potable water service is intended to describe a class
of water supply that 1s suitable for purposes other than
human consumption pursuant to regulatory constraints. It
is important to point out that non-potable water service
can include such sources as local groundwater supplies,
local stream supplies, as well as reclaimed wastewater •

2. The term reel aimed water or reel aimed wastewater is uni-
versally used to describe the end product of sewage
(wastewater) that has been adequately treated to meet the
level of quality appropriate t9 given use.
3. Sub-potable water --This is a recent term promulgated by
the Metropolitan Water District of Southern California to
identify a class of water below that of potable water. For
the purposes of the CRMWD, the terms non-potable water and
sub-potable water are synonomous •
In 1977, the Encina sewerage agency developed a significant
problem in terms of sewage tre.atment capacity which negatively
affected several of its member agencies. As a result of that
situation, several member agencies of Encina proceeded with
individual plans for the construction of wastewater reclamation
plants in order to provide fo·r sewer service capacity. As a
result of this surge of new interest and activity in wastewater
reclamation, the CRMWD became the focal point of the several
marketing analyses inasmuch as the bulk of the agricultural
activities and potential urban developments are located within
the boundaries of the District. Inasmuch as the CRMWD's important
responsibility of community water resources management would
be substantially impacted by these new developments, the District
expanded its spheres of activities in working with the San Diego
Regional Water Reclamation Agency and the San Diego Water
Reuse Study. Ultimately, the Water District became a charter
member of the Association of Water Reclamation Agencies of North
County, a coordi nat i·ng group 1 ocated in the North San Di e·go
County area.
This master plan study represents the first formal coordination
and implementation effort directed at the results of the several
sewerage agencies who have actively pursued their own projects,
and are now in an operational mode capable of producing non-potable
water. It is very important to maintain the continuing commitment
of all of the agencies involved in this new era of providing for
a dual water supply to our various communities so they wi 11
actively pursue an aggressive non-potable water supply program •

IV • PROJECTED NON-POTABLE WATER SUPPLY NEEDS AND FUTURE MARKETING
PROGRAM
As mentioned earlier, the CRMWD service area was targeted as a
prime marketing area for non-potable water as generated by the
several wastewater reclamation plants. The various engineering
studies sponsored by the City of Carlsbad, as they launched their
wastewater reclamation program, went into great detail with res-
pect to t h.e market i n g of non -pot ab l e water. We di rec t you r
attention to the reports listed in the Bibliography which contain
a wealth of information regarding the future utilization of
non-potable water. A detailed review of these reports indicates
that at this time, there are aaditional studies being conducted
concerning the chemical quality of water that can be used in
various sectors of the CRMWD service area. In particular, the
Agua Hedi onda Creek wat·ershed; upstream of El Cami no Real, is
being analyzed. As a consequence, at this time there are still
limitations upon certain locations where the various supplies can
actually be utilized. This being the case, the CRMWD has focused
its attention to the areas where at some future time, dependent
upon quantity, quality (chemical), and costs, non-potable water
can be utilized. In this arena, we have identified three separate
specific potential marketplaces, listed as follows:
1. Public facilities utilizing water service for open space,
greenbelts, landscaping, ornamental lakes, and other such
pastoral and recreational uses. In this broad category, the
largest potential users of non-potable water would be the
proposed Macario Canyon Park of the City of Carlsbad, the
proposed regional parks of the County of San Di ego -Lake
Calavera and Batiquitos Lagoon, and the numerous public
open-space equestrian trails and greenbelt areas that wander
through the various areas of the City of Carlsbad and are
common to the CRMWD service area. Additionally, non-potable
water service would be made available to the State of Cali-
fornia -South Carlsbad Beach, the State of California -
Cal Trans for the extensive freeway landscaping along
Interstate 5, the proposed landscaping on Highway 78, the
Palomar Airport area, the smaller public parks and public
school campus~s sites that dot the service area.
2. Private devel.opment uses -1 andscapi ng, greenbelts, golf
courses, ornamental lakes, and other such secondary water
supply uses. In this particular non-potable water service
usage category, the City of Carlsbad, the principal land-
use, planning and control agency. within the CRMWD, has
extensive policy programs with respect to landscaping and
beautification of the countryside. As a matter of fact,
in some instances, there are rather intensive landscaping
programs from the standpoint of water usage so that this
would tie a strong potential marketplace for non-potable
water.

3. Industrial/Commercial -specialized needs for secondary
water service. In this last category, Ute example given
earlier in this report relating to a propo~ed petroleum
refinery is an example of a specific, special non-potable
water service customer. Because of the potential of some
rather substantial volumes of non-potable water se·rvice
that can b.e made available, it is entirely possible that
we could have, in the future, a major industrial-commercial
activity that could have a demand for process or cooling
water of a quality that can be met by a properly treated
non-potable water.. This woul ct be an ideal example of a
potentially cost-effective water reclamation and reuse
within the sphere of non 7 potable water service.
In 1979, CRMWD worked in conjunction with the San Diego Water
Reuse Study in conducting a marketing survey among the then
agricultural customers of the district. A total of 20 inquiries
were sent out to the customers and si )(. responses were received
from the active customers of that time. In terms of total po-
tential water volume, there was a positive response from the La
Costa Golf Course for utilization of some 500,000 gallons per
day for golf course irrigation subject to the quantity and qual-
ity constraints that woul ct be expected. The next response in
the order of magnitude was a large floral enterprise, and here
again, the projections for non-potable service were based upon a
large-scale agricultural pursuit which did not have a firm pros-
pect of continuing for a long term. Insofar as public facilities
such as the schools system, the freeway, and the local parks,
very little potential in terms of significant volume of non-
potable water was expressed via the questionnaire.
The Lake Cal avera Hi 11 s -Master Planned Community development
submitted a comprehensive set of information as to their pro-
jection of "potential irrigation areas using reclaimed water".
Briefly, the submittal indicated that some 500 acre-feet per
year would be utilized within their 800-plus acre development on
a 5-year development time mode. In addition, the flow rate
of some 450,000 gallons per day was estimated. As matters now
stand, the first unit of the Master Planned Community, comprising
138 single-family dwelling units, currently utilizes potable
water service for landscaping. The second phase, a development
of 230 dwelling units {duplexes and four-plexes), will likewise
be served with potable water service for all landscaping.
At the present time, the City of Carlsbad is moving forward with
a comprehensive policy-program in their land-use regulatory role
to require dual water systems and use of non-potable water when
such becomes available. To date, no specific development projects
have moved forward with actual construction of dual water systems
within the service area of the CRMWD •
In view of this significant policy direction of the land-use regu-
lating agency of our service area, namely the City of Carlsbad,
it became very important that the water resol!rces management

agency, CRMWD, respond rapidly with a functional system to serve
the new marketplace.
Accordingly, there is a need for a well-planned and organized
marketing program which will have a firm financial foundation
upon which a customer can project the benefits that accrue,
while taking into account the substantial financial burden for
the construction of a complete secondary or dual water system
within the customer's area of activity. From the standpoint of
the producers and CRMWD, the distribution and marketing agency,
firm contractual arrangements wi 11 be necessary to insure the
stability of the "commodity" as the emerging program develops.
It is very important to recognize that the concept of a "cooper-
ative" among all of the producers as well as the di stri bu tors
wi 11 be the key element in organizing a cost-effective non-potable
water service program in the entire region, as well as the CRMWD
service area.
One contractual arrangement has been achieved to date involving
the CRMWD, Buena Sanitation District and the Daon Corporation.
The latter two entities own and operate the Shadowridge Wastewater
Reclamation Plant in Vista. The existing contract calls for the
plant to supply a quantity of non-potable water for distribution
by CRMWD at the Koll Company construction site adjacent to Palomar
Airport. The three-party agreement can form the basis for future
contractual arrangeme.nts between the District and other non-
potable water producers. The entire contractual documents for
this new venture are included in the Appendix of this report.
For the purposes of this Master Pl an Study, the assignment of
defined volumes of non-potable water service to specific areas
of the CRMWD has not been attempted. Such an assignment would
not be productive given the attempt of this initial evaluation
of potential customers. Given the locations and sizing of the
facilities constructed to date, there is substantial flexibility
at this time to move the modest volumes of water that can be
expected to be utilized in the next three to five years. At
this point, it should be pointed out that master pl an studies,
such as this, are viable documents that should be continually
updated and assessed. However, in no event should they be
permitted to lay delrmant in excess of five years from their
inception.
We do invite the careful review of the numerous reference docu-
ments which contain detailed data as to future projections. The
consensus of these reports indicates a range of 3.0 to 5.0 mgd
(3,000 to 5,000 acre-feet per year) of non-potable water supply
will be available to fulfill the initial marketplace needs. The
only limitation now existing upon the facilities identified in
this Master Plan Study is the practical limits of pipeline capaci-
ties, based upon the economics of pressure gradients and the need
for supplementary pumping of the water supply. With a 12-inch
diameter minimum pipeline size, quantities on the order of 3 to 4

mgd can serve as the "starter" system for non-potable water
service. Ultimately, the entire network of pipelines, both
arterial and local service lines, wi 11 develop ba~ed upon the
precise engineering design of specific neighborhood non-potable
water systems. Because of the variety of landscaping themes and
relative levels of intensity of "greenbelt areas", there will
be a wide range-of water demands within the service area •

v • CURRENT AND PROJECTED SOURCES OF NON-POTABLE WATER
We now come to the heart of the identification of the non-
potable water system that will make the entire program a

A careful analysis of the information contained in "Table A"
W i l l q U i Ck l y i SO l ate the fa Ct that the CR MW D s.e r Vi Ce are a ha S
virtually an unlimited source of non-potable water from reclaimed
wastewater in terms of volume. Several detailed studies that
have al ready been conducted would indicate that the successful
reclamation program must have ample reserve production capacity.
At this point, it. is very important to point out that this Master
Plan Study is limited only to the distribution and marketing of
nonpotable water. Accordingly, we make no attempt to isolate
and identify the areas of various additional treatment plant im-
provements necessary in order to attain the quality requirements
as set forth by the appropriate regulatory agencies. Stated
another way, CRMWD would look to the producers of non-potable
water service to have the firm ~nd direct responsibility for the
production of a water supply that wi 11 meet all of the re qui re-
ments in terms of regulatory agencies, and the customer who will
be served.
Because of our working experience and k~owledge of the CRMWD ser-
vice area, we do offer suggestions as to the potential future of
other sources of non-potable water. With respect to reclaimed
wastewater, we believe the proposed Palomar Airport treatment
plant site (northeast corner of Palomar Airport Road and El Camino
Real) is a viable site. The site is a point of concentration of
the large volumes of raw sewage which would be pumped from the
communities of Vista, Buena, and San Marcos. There would be a
substantial economic advantage to have a large reclamation plant
in the Palomar-El Camino Real area (elevation 275-300) so as to
take advantage of the head available for distribution of the
non-potable water. From the standpoint of economics, one must
always remember that it is more costly to pump raw sewage than
it _is to pump treated wastewater. We also see the potential of
a local wastewater reclamation plant in the area of the proposed
community high school campus on Cannon Road to the north of El
Camino Real. In fact, this proposed site could have a direct
tie-in with the existing Lake Calavera facility as will be
further discussed in this report.
As we have mentioned several times previously, while there is a
current emphasis upon treated wastewater being the non-potable
water supply, we should not overlook the potential of our local
water supplies. In the case of the CRMWD, the several stream
flows and the existing well field of Agua Hedionda Creek north-
easterly of El Cami no Real in the area of the Rancho Carlsbad
mobilehome park have possibilities. In the case of the stream
flows, the CRMWD, on a timely basis, should evaluate the potential
of diverting waters to the several storage reservoirs that could
be developed. These waters could even be pumped directly into
the system in the spring and early summer months for however
long there is sufficient run-off.
In the case of the Agua Hedi onda well field, an inventory would
be necessary of the potential yield from the basin tied together

with a vigorous economic analysis of the cost of sufficient
demineralization so that the chemical quality -requirements of
suitable non-potable water service could be met. Of•even greater
importance and significance would be the vast potential of
restoring the San Luis Rey River groundwater basin to produce
a local water supply of satisfactory quality, again within the
framework of a vigorous economic analysis. Additionally, this
is very important from the standpoint of being the one significant
source of a local water supply in the event of a major water
shortage or crisis in the Carlsbad community, the service area
of the CRMWD, and City of Oceanside (who in the past ·has utilized
the San Luis Rey River water supply).

VI. EXISTING FACILITIES AND PROJECTED INTEGRATION OF FACILITIES
IN DISTRICT SERVICE AREA
Exhibit "A" delineates in detail all of the public wastewater
reclamation facilities of the City of Carlsbad, Buena Sanitation
District, San Marcos County Water District, and the Leucadia
County Water District, In addition to the actual treatment plant
facilities, Leucadia County Water District, Buena Sanitation
District, and the San Marcos County Water District have existing
"fail safe" effluent lines that transport treated wastewater to
the ocean outfall system of the Encina regional facilities.
CRMWD has taken advantage of the strategic locations of these
new pipeline facilities. In recognition of our emerging role
as distributors of the non-potable water service, arrangements
were made during construction to actually build a total of six
outlets along both the San Marcos and Buena effluent pipelines.
In every instance, they are positioned to take advantage of
extending pipeline facilities to current or projected market-
pl aces, utilizing the existing rights-of-way of CRMWD. In
addition to the construction of the several outlets, CRMWD was
fortunate to enter into a cooperative agreement with the City
of Oceanside for the construction of a 12-inch non-potable water
service line in the Highway 78 -El Cami no Real freeway inter-
change bridge. This line permits an inter-tie between the City
of Oceanside's advanced wastewater reclamation system and the
potential customers of the CRMWD and the City of Carlsbad, We
would add that at the request of Cal Trans, there has al ready
been constructed in ·this new pipeline two outlets for future
freeway landscaping. The proposed master plan which has emerged
from this study report identifies the total integration of all
of the existing facilities built by local public agencies so
that there is maximum use of the pipeline facilities constructed
to date •
The Encina Water Pollution Control Facility (EWPCF) stands out
in its magnificence as a result of its recent upgrading and
expansion, so as to permit an ultimate expansion to 45 mgd •
Al though there is a full secondary treatment level for the
current 22.5 mgd plant, efforts are now underway to permit the
overall treatment p'l ant operation to conform to an advanced
primary level of sewage treatment. Accordingly, any significant
level of wastewater reclamation at the EWPCF will require a
major construction effort. Because of its elevation, i.e •
approaching sea level, the reclamation of wastewater at the
EWPCF would be expected to take pl ace at some point well into
the future, at such time when the required. volumes for non-potable
water service overtax all of the upstream facilities located at
higher elevations.

VI I. DESIGN CONSIDERATIONS FOR NON-POTABLE WATER SYSTEM
As a basic policy statement, CRMWD intends to operate its non-
potable water system as a supplement to the potable water system
so that in all particulars, there would be identical design
parameters and considerations for the non-potable water service
that are currently active for the potable water system. Recog-
nizing that the prime goal is to offer to the water customer the
secondary water supply at the potable water convenience 1 evel,
it is very important that there not be introduced so-called
"second level" service requirements.
Because the heavy emphasis will"be upon landscape irrigation, the
non-potable water system wi 11 require a rather high 1 evel of water
service pressure. Accordingly, the entire service area will be
laid out to all~w a minimum water pressure of 40-50 pounds per
square inch (PSI) up to a maximum of 140-150 PSI. From our exper-
iences in operating the potable water iervice, we have a rather
hilly terrain so that it would be very expensive to try to main-
tain a uniform water pressure throughout the area. In the case
of the proposed master plan system, there will be more localized
areas of individual pumping stations because the existing network
of fai 1 safe 1 i nes has, in several instances, 1 ow-pressure fl ow
characteristics. Of course, in time, as there is paralleling of
these facilities, there can be more precise engineering designi
to take advantage of pressure conditions wherever possible,
All pipeline sizing at this time is for a minimum of 12-14 inches
in diameter. This size range has been established in view of the
fact that the potential marketplace as currently assessed will
account for a rather modest volume of flow. Design velocities of
8-10 feet per second utilizing asbestos cement or poly-vinyl
chloride pipe material will allow for flows in the magnitude of
4,0 mgd •
The non-potable water system wi 11 have a marked departure from
the potable water system from the standpoint of storage require-
ments needed to compensate for the peak flow conditions that
will occur on a daily basis. The non-potable storage system
will need to accommodate for the variation in production rate at
the reclamation plant and more importantly,.the seasonal produc-
tion and usage vari.ation will have to be accommodated, In the
case of local service areas, detailed design of the irrigation
system will yield the regulatory storage needs, For seasonal
storage, the San Marcos County Water District's new facilities
are an important "first on line" reservoir. Within our District
service area, the existing Lake Calavera plant owned by the City
of Carlsbad -Water Department has great potential as a seasonal
storage facility. More detailed studies will be appropriate at
a future time when the regulatory constraints are resolved for
all parties concerned, ·

One important sidelight to the operation of the non-potable water
system involves having faci 1 it i es where the non-potable water
supply can be augmented by the freshwater supply 1 n the event
there is a reduction or termination of production at the waste-
water reclamation plants. At CRMWD, we would propose that the
non-potable water service reservoirs be located adjacent to our
potable water reservoirs and in the event there is a need to
supplement the supply, there would be a simple "overflow" arrange-
ment. Such an overflow system from the potable supply to the
non-potable supply would be accomplished with a Health Department
approved air-gap separation type of service. Additionally, there
may be a pl an developed to construct the non-potable supply
reservoirs consisting of ground-level containers manufactured of
a synthetic fabric. This approach would minimize both operating
expenses and capital costs.
From the standpoint of pi pel i n-e design, there must be positive
identification of the potable and non-P.otable systems to assure
the maximum protection of the public health. The construction
of a public non-potable water system is practically identical to
that of the potable water system, with the fundamental exception
being the need to incorporate a sufficient and distinctive marking
so as to permit the underground and ground surface faci 1 i ti es
and appurtenances to be properly identified. There is now a
wealth of detailed rules/regulations and construction specifica~
tions with respect to the construction of non-potable water
systems. The CRMWD is in the position to review such information
so that the preparation and adoption of specific rules and regu-
lations and design and construction standards for such systems
can readily be accomplished. This element of the overall non-
potable water service program wi 11 be handled as a separate
matter.
As mentioned earlier, one of the basic policy positions of the
CRMWD wi 11 be to establish non-potable water service at a com-
parable level with potable water service. This will assure that
all pipeline facilities, valving systems, pumping systems, and
storage facilities will be de5igned and constructed on the basis
of good, functional design procedures, utilizing proven materials
and equipment. Combined with good construction techniques, a
first class, functi'onal distribution system will result. We
would anticipate that the CRMWD's standards shall adhere to
the current practices that are now proving successful here in
Southern California •

On the basis of the evaluation of all of the existing non-potable
water system facilities in the CRMWD service area, as well as the
strategic locations of the several existing and potential sites
for the production of non-potable water, our task has turned to
identifying the first elements of a totally integrated arterial
distribution system to supply our emerging marketplaces. Exhibit
"A", our "Master Plan for Public Non-Potable Water System", has
been formulated with the intent of linking together all of the
currently existing supply sources as well as the Lake Calavera
Hi 11 s reel a mat ion pl ant. The Shadowri dge pl ant and the Meadowlark
plant have existing ''failsafe facilities" which join together to
the west of El Camino Real and south of Palomar Airport Road and
then travel westerly to the EWPCF plant site. Our first goal is
to be able to take advantage of the utilization of existing out-
lets which have already been constructed.in these two lines. Each
of the outlets, 12 inches in size, have been located to accommodate
a potential local service area and also to take advantage of
additional distribution facilities from these take-off points
paralleling the CRMWD's existing potable water lines. We note
that the master plan identifies in some detail the existing potable
water system facilities, and we have done this to highlight the
fact that both the agricultural irrigation customers as well as
our urban customers are currently utilizing the potable water
facilities as delineated on the exhibit map.
St art i n g w i th the s o·u the r l y sector where the ex i st i n g Leu cad i a
reclamation plant stands ready to be activated, we are proposing
a major line to be extended to the north side of the Batiquitos
Lagoon, then westerly, and ultimately terminating at the junction
point of Lagoon Lane and Poinsettia Avenue just east of Interstate
5. This routing would provide ample opportunity for sufficient
volumes of non-potable water to care for all of the potential
needs of a future regional park or greenbelt and landscaping for
urban developments all along the north shore of the Batiquitos
Lagoon. There is an additional east-west tie from the old Coast
Highway at its intersection with the proposed Poinsettia Avenue
moving easterly and northerly along a ridge line, where we have
extensive irrigated 'agriculture, easterly to El Camino Real, then
northerly a short di stance to intersect with the existing San
Marcos failsafe line. You can see immediately from this layout
that the entire southern area of the Water District westerly of El
Camino Real can have ready access to non-potable water service
from either the Leucadia system or the San Marcos system and, de-
pending upon the availability and quantities, there would ulti-
mately be total integration of the full production capabilities
of those two agencies •
In the central area of Palomar Airport Road, westerly of El Camino
Real, we have an important linkage between the San Marcos line and
the Buena line along El Camino Real. Here again, this gives us

the flexibility of an interchange of flows between the San Marcos
facility and the Buena facility. Additionally, in the event the
proposed Palomar Airport reclamation facility is determined to be
the most practical location, these pipelines would serve as trans-
portation facilities from that location.
Moving northerly .and westerly from the intersection of Palomar
Airport Road and El Cami no Real, the District would propose an
arterial line along the north side of Palomar Airport and into
the area of the Carlsbad Research Center industrial development •
We fully expect that this new 55O-acre industria•l-commercial
center will become an active marketplace for non-potable water
service, particularly as evidenced by the plans for a landscaping
program, together with a large ground cover area for manufactured
slopes. The routing of a non-potable water service line in
College Boulevard, which would have linkage from Palomar Airport
Road northerly all the way to Highway 78, has led us to the idea
that the line should proceed northerly,_crossing El Camino Real,
moving to the area of a proposed reclamation plant at a new high
school site, and continuing northerly to Lake Calavera.
At this point, we should explain that in the day to day operation
of a vast arterial water system network, you must have distribu-
tion storage and additionally, seasonal storage. There have been
previous projections as to potential sites for seasonal storage
reservoirs; however, we believe that the Lake Calavera facility
merits a very careful analysis inasmuch as the existing lake is
currently serving no functional purpose insofar as its owner,
the City of Carlsbad -Water Department, is concerned, There is
also the potential that the activation of the Buena Vista Creek
reclamation facility of the City of Oceanside may result in the
construction of an arterial pipeline easterly along Highway 78
which could ultimately provide a routing to store water in Lake
Calavera.
Along this sector of the College Boulevard pipeline, there is
also the potential of constructing a pipeline facility that
would tap the stream flow of-the Agua Hedionda Creek, a little
under one mile east of the future College Boulevard location.
The City of Carlsbad' has constructed the Lake Calavera Hills rec-
lamation plant; however, it cannot become operational until such
time a ''failsafe line" has been constructed to tie into the EWPCF
ocean outfall. We have identified a possible routing of the fail-
safe line that could be constructed from El Camino Real southerly
in the right-of-way of an existing flood control channel, be
extended across the ''slough" area of the Agua Hedionda Lagoon and
tie in with an existing roadway/CRMWD pipeline system intersecting
with the fail safe line now located in Palomar Airport Road. This
proposed routing would have the potential of serving the Kelly
School, the adjoining City of Carlsbad park site area, and the
possible future "wetlands" area. Of course, a portion of this
proposed routing would also traverse the City of Carlsbad's new

i,.,
''Macario Canyon Regional Park Site" so that there could be
functional uses within that park setting,
We have mentioned the potential intertie of the City of Oceanside's
Buena Vista Creek reclamation facility into the overall network.
The master plan does not specifically identify a pipeline tie-in,
We believe that it is more appropriate to have the City of Ocean-
side and the City of Carlsbad -Water Department review that area
of interest more critically and then come forward with a plan
that would serve the functional needs of those agencies as well
as potentially being assimilated with the CRMWD's master plan.
The identification of the proposed network of arterial pipelines
has as its basic goal the stimulation of interest and under-
standing of a concept that the non-potable water supply program
for the entire region has as its basic foundation of success a
"cooperative" approach. This· cooperative approach would be
with regard to sources of supply, facilities and a full integra-
tion of the subsequent new construction that will bring all
of the interacting features together. In some respects, we
are uniquely blessed by the fact that several programs are
al ready in motion and that the entire region can benefit from
the efficiency and the economics of a fully integrated system,
While there is a host of details to be identified and attended
to, the overall strategy from the standpoint of the network of
distribution systems .is to bring into motion the full range of
transferring waters from the areas of production and availability
to the areas of specific need based upon a practical scope of
marketing •
The character of this master plan network is such that no attempt
is made at this point to identify in detail pipeline sizes (other
than the minimum size of 12 inches}, their lengths, pressure
ranges, locations and sizes of pumping stations, locations and
sizes of storage reservoirs, and all of the other details that
are involved in the design of an operating water system. From
the standpoint of economics and practicability, experience has
shown that there needs to be a specific non-potable water service
program identified, following which there should be a vigorous
and detailed engineering analysis of the physical facilities
that are required ahd ultimately an economic analysis that can
demonstrate the viability of the non-potable water service
program to integrate with the existing or planned potable water
system facilities •

IX • SUMMARY AND CONCLUSIONS
This report has identified in some detail the multitude of sources
of supply for public non-potable water service that could be made
available to existing and future water customers of the CRMWD.
At a time when the character of the CRMWD is changing from "dry-
lands" and agricultural areas to intensive urban developments,
we are witnessing a trend for vast expanses of open space, land-
scaping, ornamental horticulture, and other uses of our local
water supply which may be very adaptable for the u~ilization of
a non-potable supply. CRMWD has had the good fortune of being
geographically located so that we can readily be served from
facilities that our neighboring·agencies have already constructed
so that we have a situation that is of tremendous advantage to
our service area.
On the basis of many years of water resources development, con-
struction and operation of vast public potable water systems, we
have the advantage to view the potential marketplace for non-
potable water service. It is our firm opinion that for a number
of reasons, not the least of which is availability and cost of
service, non-potable water service will emerge as a cost-effective
and community-sustaining program.
There has been specifically identified in our master plan an arte~
rial system to fully integrate all of the existing and potential
sources of our supply. While the dominant role will be played by
wastewater reclamation facilities, we also have directed attention
to the potential of local stream flows as well as existing ground-
water supplies •
This overview and master plan report is now ready for review and
input from all of the sectors of the public and business enter-
prises as well as all interested, neighboring and participating
public agencies who are involved in wastewater reclamation and
reuse. Upon the conclusion of public discussion and the formal
proceedings by the Board of. Directors of the CRMWD, we would
specifically recommend the formal adoption of the plan. Then
the Board should establish a formal implementation program,
which to a large measure would involve specific contractual
negotiations and agreements with the several "producers" of
non-potable water. As with the case of any major project of
this scope, the ultimate success of this non-potable water
service program wi 11 be based upon the ability to design a
financing program that wi 11 result in a cost-effective water
service which will have to carry the burden of the construction
and operation of a complete "dual water system" within the CRMWD
service area.

Dear Mr. Delaney:
The purpose of this letter is to request your approval of our District's pro-
posal to distribute secondary effluent within the Agua Hedionda Basin near
Palomar Airport.: This water, amounting to approximately 100,000 gallons per
day for about three months (representing an initial increment) would be
supplied by Buena Sanitation District's Shadow Ridge Treatment Plant. Costa
Real Municipal Water District would supply it for construction compaction
purposes for the Carlsbad Research Center development. This development has
moved very rapidly and grading will begin by October 1.
I understand the basin discharge standards have been amended to a limit of
3500 mg/1 TDS. Effluent from.the Shadow Ridge plant would contain 1,000 mg/1
or less. Legal arrangements for the acquisition and distribution of this
effluent are being worked out now. They will be patterned after the agreement
between Buena Sanitation District and Vista Irrigation District. We would be
happy to conform to any restrictions you would impose, as we are taking a con-
servative approach to the entire water reuse program within our District. We
believe this approach will produce a viable reclamation program in the near
future.
The initial application of effluent for construction purposes would be a sig-
nificant step in North County, where, as you know, several agencies have formed
an organization to promote reclamation. Publicity of Costa Real 's project
would be of mutual benefit to our District and the Regional Board. In this
regard, you are invited to attend one of our Board meetings if you are able to
approve our request to discharge limited amounts of effluent for the purpose
described above. I look forward to discussing this with you further .
Sincerely,
William C. Meadows

Dear Mr. Meadows: I '

This is in response to your letter of September 9, 1981, regarding the
proposed use of reclaimed water for construction compact"ion purposes as
in the Agua Hedioncla Basin in the vicinity of Palomar Airport. I under-
stand you could possibly becin usin(l the reclaimed water as early as

As you lrnow, the EeGione.l Board a.'Ilended their Basin Plan in )!,arch of 1981
to relax groundwater standards in a number of areas in an attempt to en-
courage the meanincful use of reclaimed water. '.!'he State Water Resources r Control Board subsequently approved the 2-l!lendments on September 17, 1981.
11111 Your proposed use of reclaimed ,,ater would occur in one of those areas.
I am quite enthusiastic about your proposal since the contemplated -use, I by replacihi; potential use of imported water supplies, is precisely the
• type of use the Rer,ional Boc,_rd had in mind when they amended their Basin
Plan. Yours, by the w,iy, is the second serious proposal fur use of reclai:ned i vater in the affected areas that ve have received since the Regional Board
._ adopted the Basin Plan 2mendrnents, I encourai;e you to pursue your proposal
and offer any c,_ssistance possible by myself or my staff to expedite the
,.. necessury procecsinc. I ,·ould be happy to appear before your board to discuss
i,,, the merits c,f your proposal.

I plan to discuss a waiver of requirements for your project with th~ Regional f Board at their September 28, 1981 meeting, If the Board does not objeci, I
i,., could authorize the initiation of the use of the reclaimed water prior to
October 1, As a contingency, in the event the Regional Board objects to a
,.. waiver of requirments, ,or to provide for a longer term use of reclaimed
~ water, I would recommend that yciu contact Mr, Coe of rrzy staff regarding
application procedures for waste discharge requirements and water reclama-
1"' tion requirements, As the process for obtaining requirements takes some
i,., time,, I recommend you contact Mr. Coe without any delay if it appears
appropriate,

Dear Mr. Meadows:
As you know I discussed your proposed use of recla:iJned water for construction
compaction purposes with the Regional Board at their September 28, 1981 meeting .
At that time, I informed the Board of my recommendation that the need for obtain-
ing requirements for the project be waived. The Regional Board did not object
to such a waiver. The Board will be considering action to formalize waivers
of requirements for many types of discharges, including ones similar to the one
you proposed, at a future meeting. However, in light of the lack of objections
to your project you may begin using recla:iJned water innnediately.
( The use of reclaimed water must be in a manner consistent with t,:Qur l-e1r~r-of
· e_eptember 9~ .j.981-.and in accord with cny.:::lm::t:t,r.::rif:.:Se:j1fenilier=zr, ... ,.981. I would
