The model also was used in developing an efficient mode of operation by identifying the recommended flow routing at the key diversion poi1~its throughout the pipeline system.The computer model allows the plan t~be up~atedas conditions change.Very few deficiencies are projected wit~hin the combined system.Relief of the majority of the deficiencies will b~provided by the following three major recommended facilities: 1.Fairview—Gisler Relief Trunk in District No.6 rel existing Fairview Trunk and Air Base Trunk Outfal]i to Treatment Plant No.1.I 2.Airport Relief Trunk in District No.7 serving th~ expanding Irvine Industrial Complex—West south of Freeway. 3.South Irvine Lift Station and Relief Subtrunk in c~istrict No.7 pumping flow from the existing Gisler-Red Hill Trunk to ~he gravity Sunflower Interceptor at a lower lift than the exi~sting College Avenue Pumping Station.

Mr.Hohener 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 No.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 within the IRWD. Three alternatives ranging from minimal involvement with the CSDOC’s 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 mgd 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—Orange 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 a1tern~tives 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.

The Consolidated Master Plan evaluates the network of the 9istricts as one system from an engineering viewpoint,without regard to District boundarJ~es. Early in the study it was ascertained that the existing trunk sewer system in Districts 2,3 and 11 lends itself very well to the correct1ion of existing and ultimate capacity constraints.The existing major trunk sy~tem can be made to carry the existing and projected ultimate flows to the appr~priate treatment plant.Existing and proposed diversion structures along wi~th relief sewers can be used to divert flows to major trunks or interceptors tha~have excess capacity available.Therefore,by optimizing the use of the existing trunk sewer system, the Districts can minimize the cost of providing for the ultimate projected flow. Capacity constraints or deficient sewers were determined •by the us~e of a computer model which compiled the existing and proposed land uses,ca1cula~ed the flow for each drainage region,and routed each flow through the appropriate~trunk system. By modeling different situations and solutions to the identified deficiencies, the most cost—effective improvements to correct the problems were ~eveloped and an estimated time period was developed.The computer model allows!the plan to be updated as conditions change. Mr.Martinson then reviewed the recommended phased construc District 2 requires three new diversion structures to diver Ana River Interceptor.District 3 will also require three I structures to divert flow from overloaded sub—trunks to the Districts 2,3 &11 11/17/82 Districts 2 &3 Receive and file excerpt re election of mayor and interim -~ appointment of alternate Director is hereby,received and ordered filed; seated as a member of the Board.

The trunk sewer collection system improvements and capacity exchanges necessary to provide for ultimate build—out of the entire District 2,3 and 11 service area will cost approximately $52 million in 1982 dollars——$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.
