CITY COUNCIL REGULAR MEETING AGENDA PACKET (2)

WATER SYSTEM MANAGEMENT PLAN OCTOBER 2024 / CAROLLO CITY OF PLEASANTON WATER SYSTEM MANAGEMENT PLAN 11 Other distribution projects in the WDSCMP include the following: 1.DS-4 Gray Eagle Connection to Kottinger Pressure Zone (FF-229 through FF-231): Pipeline to move water from the Gray Eagle pressure zone to the Kottinger Pressure zone as described in the WDSCMP. 2.DS-5 Lemoine Bypass Pipeline Project: This project constructs piping improvements that reduced water age near the Lemoine development in the Moller 770 pressure zone. Refer to the WDSCMP for more details. 5.2.3 Distribution System Fire Flow Projects The WDSCMP also identified fire flow improvements. The WDSCMP categorized fire flow capacity deficiencies above 30 percent deficient as Priority A. The Priority A fire flow improvements are documented in the WDSCMP. 1.DS-2: Priority A Fire Flow Deficiencies (Defined in the WDSCMP). 2.DS-3: Kilkare – Sunol Priority A Fire Flow Deficiencies (Defined in the WDSCMP). 5.2.4 Rehabilitation and Replacement Projects The rehabilitation and replacement (R&R) projects have been developed based on the condition assessment effort. The facility condition assessment technical memorandum is included as Appendix D. Based on the findings of the condition assessment as well as the criticality evaluation that was conducted as part of the AWIA project, the following capital projects were developed and prioritized. The descriptions below include major drivers for rehabilitation, but it is intended that the entire facilities are rehabbed as part of each project to cost effectively extend their useful life. 1.RR-1 Tank 1300: Interior tank corrosion 2.RR-2 McCloud Tank and Pump Station: Decommissioning and demolition 3.RR-3 Foothill Pump Station: Rehabilitation includes electrical and instrumentation replacements and upgrades, pump and valve replacements, security and road improvements. 4.RR-4 Tank Inspection Program: Costs associated with the internal inspection of the City's storage tanks and reservoirs. 5.RR-5 Vineyard Pump Station: Rehabilitation includes electrical and instrumentation replacements and upgrades, pump and valve replacements. Project should include a preliminary design to evaluate breaking the City’s largest pressure zone (Mega Zone) into three separate pressure zones. If so, the Vineyard Pump Station capacity will need to be increased as discussed in the WDSCMP. 6.RR-6 Kottinger Pump Station: Rehabilitation includes electrical and instrumentation upgrades, valve replacements and upgrades, lighting improvements, and crane improvements. 7.RR-7 Grey Eagle: Grey Eagle is assumed to be decommissioned since it will no longer be needed after construction of project DS-4. However, if the Grey Eagle connection to Kottinger Pressure Zone project does not occur in a timely manner, then rehabilitation of the pump station will be needed. Page 442 of 658
