Utilizing this database, Kermedy/Jenks Consultants will provide a list of <br />recommended and prioritized improvements and a strategy for reducing the <br />potential for nitrification. Estimates of the probable cost of construction for these <br />improvements will be prepared. <br /> <br />The specific deliverables from Task 1 that will be included in the final report <br />include: <br /> <br /> · The deadend database <br /> <br /> · The prioritized recommended list of system improvements, including an <br /> estimate of their probable cost of construction <br /> <br />In order to complete this task, RWC will provide the water system digitized <br />mapping and other distribution system maps available to conduct Task 1. Any <br />deficiencies in the electronic data will be reported to the City. In addition RWC <br />shall provide an estimate of the water usage from various classifications of <br />customers for the irrigation and non-irrigation months. <br /> <br />Task 2 - Storage Facilities Assessment for Chloramine <br />Conversion <br /> <br />In Task 2, Kennedy/Jenks will evaluate physical configuration of the inlet/outlet <br />piping and the operation and management of RWCs water storage facilities. <br /> <br />Kennedy/Jenks Consultants will identify and provide cost estimates of the <br />improvements and changes necessary at the water storage facilities. These <br />recommendations should take into account the conversion from chlorine to <br />chloramines as a final disinfectant and its effect on water quality. <br /> <br />This task will consist of the following steps: <br /> <br /> · Evaluation of operation, water age and mixing behavior in storage <br /> facilities to minimize chloramine decay and prevention of nitrification, <br /> <br /> - Identify inlet/outlet modifications and improvements or changes needed <br /> to provide for water quality monitoring under conditions of <br /> chloramination, including additional sampling stations, and <br /> <br /> · Evaluate the inlet/outlet modifications with respect to cost-benefit <br /> analysis and operational flexibility for each storage facility, providing <br /> implementation schedules to meet the planned conversion to chloramines <br /> by SFPUC. Costs will be broken out into upfront capital and ongoing <br /> operations. <br /> <br /> · Review high water and low water setpoints that operate pumps and/or <br /> valves that control the filling and draw down of the water storage <br /> facilities to determine their impact on water age. <br /> <br />The deliverable associated with Task 3 will be a separate chapter in the final <br />report that contains the results of the reservoir evaluation. <br /> <br />In order to complete this task RWC will provide drawings of all water storage <br />facilities, operational setpoints, and available records of pump operation or other <br />records that can be used to determine the frequency and volume of filling and <br />drawdown of the facilities to be evaluated. <br /> <br /> Budget and Schedule 3 <br /> <br /> <br />
