Districtksj . Active Alternate 2 &3 Carrey J.Nelson Norma A.Ricks 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. —2— ~J ~i ~~~~ •1i -‘.‘~istricts 2,3 &11 11/17/82 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. _________________________________ Following a lengthy discussion by the ________________________________ Boards,it was moved,seconded and duly carried: District 3 Ad~journment Moved,seconded and duly carried: That this meeting of the Board of Directors of County Sanitation District No.3 be adjourned.The Chairman then declared the meeting so adjourned at 7:40 p.m.,November 17,1982.

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 —2— D&stricts 1,6,&7 11/17/82 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.
