Report of Engineer re Consolidated The Chairman recog&ized Don Martinson of
Master Plan of Trunk Sewers Lowry and Associate~,who reviewed the
draft of the Consol’idated Master Plan of
Trunk Sewers for Districts 2,3 and 11 prepared by his f irk
Mr.Martinson summarized the history of the respective Dis~tnicts’~sewer system
expansion to keep pace with the rapid development in metropolitan Orange County.
The Consolidated Master Plan evaluates the network of the pistri~ts as one system
from an engineering viewpoint,without regard to District bounda~ies.
Early in the study it was ascertained that the existing tr~.rnk sewer system in
Districts 2,3 and 11 lends itself very well to the correc~ion of existing and
ultimate capacity constraints.The existing major trunk system ~an be made to
carry the existing and projected ultimate flows to the app~opnia~e treatment
plant.Existing and proposed diversion structures along wIth re]Jief sewers can
be used to divert flows to major trunks or interceptors th~t hav~excess capacity
available.Therefore,by optimizing the use of the existing trunk sewer system,
the Districts can minimize the cost of providing for the ultimat~projected flow.
Capacity constraints or deficient sewers were determined •by the use of a computer
model which compiled the existing and proposed land uses,~alcul~ted the flow for
each drainage region,and routed each flow through the appropnia~e trunk system.
By modeling different situations and solutions to the iden~ified deficiencies,
the most cost—effective improvements to correct the proble~ns wer~developed and
an estimated time period was developed.The computer model allow~s the plan to be
updated as conditions change.
The land use and corresponding wastewater projections reflect an increase in
sewage flow of about 23 mgd at build—out over the 1975 Lan~i Use P~lan.These
changes were mostly in the cities of Anaheim,Fullerton,H~.intington Beach and
Seal Beach,and reflect changes in zoning to accommodate increase~density.
Despite the significant unused capacity in the lower reach~s,many of the
upstream reaches have computed flows which are nearing or have exceeded their
design capacities.
.
Mr.Martinson then reviewed the recommended phased construFtion ~rogram.
District 2 requires three new diversion structures to divert flo~to the Santa
Ana River Interceptor.District 3 will also require three~new di~version
structures to divert flow from overloaded sub—trunks to the ~nott Interceptor.

District 11 requires four new diversion structures to relieve capacity
constraints in the area of McFadden,Heil and Edwards in Huntington Beach.
also reviewed proposed capacity exchanges between Districts in existing
facilities that would effectively optimize the use of the existing major
interceptor sewer systems.
The trunk sewer collection system improvements and capacity exchanges necessary
to provide for ultimate build—out of the entire Dist~ict 2,3 and II service area
will cost approximately $52 million in 1982 dol].ars——$28.5 million for District
2,$8.4 million for District 3 and $14.8 million for District 11.
In addition to recommended capacity exchanges and construction of relief sewers
the ‘engineer recommended a monitoring program to verify computed capacity
constraints with actual field measurements,and also to monitor sewage quality
for possible harmful industrial discharges.

___________________________________
The Chairman recognized c~onrad Hohener of
-Boyle Engineering ~orporation who reviewed
the draft of the Conso1id~ated Master Plan
of Trunk Sewers for Districts 1,northern half of 6,and 7.
Mr.Hohener summarized the history of the respective Districts’sewer system
expansion to keep pace with the rapid development in metrc~poiitah Orange County.
The Consolidated Master Plan investigates the possible joint usat~e of the
combined systems to maximize use of the existing faciliti~s in pkoviding an
efficient system of trunk sewer facilities,without regard to Di~trict
boundaries.
The current land—use planning objectives,which serve as ~he basis for
projecting sewage flows,were reviewed with the various p]~anning~agencies having
jurisdiction in the master plan service area.Major variances with the Joint
Districts Ultimate Land—Use Plan prepared in 1975 were not~ed.A~hyd±au1ic
analysis of the combined trunk and subtrunk sewer system ~as accomplished by
developing a computer model of the combined pipeline network to ~roject sewage
flows to compare them to the pipeline capacities,and then~to fl~g deficiencies.
The model also was used in developing anefficient mode of operation by
identifying the recommended flow routing at the key divers1ion po~Jnts throughout
the pipeline system.The computer model allows the plan t~be up~ated as
conditions change.Very few deficiencies are projected wipin th~e combi-ned
system.Relief of the majority of the deficiencies will be provided by the
following three major recommended facilities:
1.Fairview—Gisler Relief Trunk in District No.6 relieving1 the
existing Fairview Trunk and Air Base Trunk Outfall SeweriNo.2
to Treatment Plant No.1.
2.Airport Relief Trunk in District No.7 serving the rapidly
expanding Irvine Industrial Complex—West south of~the San Diego
Freeway.
3.South Irvine sift Station and Relief Subtrunk in District No.7
pumping flow from the existing Gisler—Red Hill Trunk to t~.he gravity
Sunflower Interceptor at a lower lift than the exiisting College
Avenue Pumping Station.
Three other relief subtrurtks,completipn of a short stretch of th~Tustin-~Orange
Trunk Sewer,and some modifications to four pumping station~in Di~strict No.7
make up the remainder of the recommended trunk sewer facili1ties.No new
facilities are projected for District No.1.Based upon current ~onstruction
costs,total estimated construction cost of the facilities ~erving1 District No.6
is $5,628,000 and $6,514,000 for those serving District No.1 7.I
The engineer pointed out that each facility had been priori&ized t~meet the
projected flow buildup requirements using available planning infor~natioñ,flow
recording data,and engineering judgment.To keep pace wit1~the e~zer changing
planning and development processes within the service area,~he also recommended
that flowtnetering be implemented on a continuing basis to provide the combined

D&stricts 1,6,&7

Districts with current data from which to establish an implementation schedule
for the facilities reflecting the actual needs of the District as they occur.
Mr.ifohener also reviewed the addendum to the draft master plan authorized by the
Boards at the request of the Irvine Ranch Water District (IRWD).The addendum
focuses on the alternative means of conveying IRWD’s wastewater to Reclamation
Plant Mo.1 as one element of their investigation into the feasibility of forming
a new sanitation district and buying capacity in the Joint Sanitation Districts
(CSDOC)facilities to serve the territory withinthe IRWD.
Three alternatives ranging from minimal involvement with the CSDOC1s system to
multiple capacity sharing opportunities have been developed.Total ultimate flow
from the IRWD planning is 41.35 million gallons per day (mgd).In each
alternative,1.35 mgd from the Upper Peters Canyon area has been routed through
District No.7’s Sunflower/Tustin—Orange Trunk system.Alternative I conveys all
of the remaining 40.0—mgd IRWD—generated flow to the CSDOC’s Treatment Plant No.
1 by a new trunk system from the Michelson Water Reclamation Plant (MWRP).The
second alternative investigates service of the lower undeveloped Peters Canyon
area by a new trunk with a capacity allotment of 7.0 ingd for the IRWD planning
area connecting to the Sunflower—Red Hill Interceptor at McGaw Avenue with the
remaining 33.0 mgd being transported by a new trunk from the MWRP.The third
alternative routes the IRWD flows as in Alternative II but considers several
capacity sharing opportunities with Districts Nos.6 and 7.In all cases it was
most economical to route flow from the Upper Peters Canyon area to the
Tustin—Orarige Trunk and to share capacity in a common trunk with District No.6
from Fairview Avenue to Treatment Plant No.1.
The life cycle costs for all three alternatives were equivalent within the
accuracy of the estimates.All alternatives also were tested for intangible
advantages,such as flexibility of operation during normal operation and
emergency situations,reliability over the long term,and opportunities for
staging the facilities to meet the flow buildup requirements of both IRWD and
CSDOC.As a result,Alternative III is recommended for conveyance of the
IRWD—generated wastewater flows to the CSDOC’s Treatment Plant No.1.
Construction of the Peters Canyon Trunk would also eliminate the need for several
existing pump stations.
The estimated total construction cost in 1982 dollars for the required new
facilities is $21,300,000 for IRWD.The net impact to the combined districts’
master plan is a reduction of $3,010,000 for District No.6 and $230,000 for
District No.7.
