Page 8 of 9 Task 1.0 - New City Wells Alternative Evaluation This task entails evaluating the water distribution system for the alternative of the City installing two new wells in revised locations as outlined below: 1. The location and capacity of the two new wells will be provided by the City after field testing is performed at Del Prado Park, Tennis and Community Park, and Hansen Park. The City will also be responsible for providing cost estimates associated with the new well facilities. 2. The water distribution system evaluation shall be performed for existing and future demand conditions against the performance criteria established in the WDSCMP. 3. The evaluation shall determine any changes to recommended improvements in the WDSCMP by providing a Revised Table 8.2. The Revised Table 8.2 shall be formatted to clearly reflect changes due to this alternative (i.e., strikethrough deleted recommendations and bold new/modified recommendations). Cost estimates will be provided for new/modified recommendations and include existing and future user breakdowns and triggers for when they are needed. 4. All recommended improvements shall be compatible with and build off near-term improvements (i.e. S-1, S-2, S-3, and BS-1) as those projects are already underway and to minimize sunk costs. Task 2.0 – Zone 7 and City Joint Wells Alternative Evaluation This task entails evaluating the water distribution system for the alternative of the City and Zone 7 installing joint groundwater facilities as outlined below: 1. The joint groundwater facilities will be operated by Zone 7. Water would be transported by Zone 7 through their transmission system and delivered to City at turnouts (i.e., 100% of water supply delivered through turnouts). 2. The water distribution system evaluation shall be performed for existing and future demand conditions against the performance criteria established in the WDSCMP. 3. The evaluation shall determine any changes to recommended improvements in the WDSCMP by providing a Revised Table 8.2. The Revised Table 8.2 shall be formatted to clearly reflect changes due to this alternative (i.e., strikethrough deleted recommendations and bold new/modified recommendations). Cost estimates will be provided for new/modified recommendations and include existing and future user breakdowns and triggers for when they are needed. 4. All recommended improvements shall be compatible with and build off near-term improvements (i.e. S-1, S-2, S-3, and BS-1) as those projects are already underway and to minimize sunk costs. Recommended improvements shall consider the need for additional turnouts or turnout boosting. Task 3.0 – Zone 7 Transmission System Workshop At the beginning of the evaluations, a workshop shall occur with City and Zone 7 staff to determine the assumed pressure ranges from Zone 7’s transmission system at each turnout for both existing and future demand conditions. Akel shall conduct the workshop including agenda, presentation materials, and minutes. Task 4.0 – Preliminary Results Workshop Preliminary results of the evaluations shall be presented by Akel in a workshop. Akel shall conduct the workshop including agenda, presentation materials, and minutes. City feedback from the workshop shall be incorporated into finalization of the evaluations.
