During the preliminary design phase, <br />Michael Baker conducted a comprehensive hydraulic analysis of <br />WUA's water supply and distribution systems, reviewed WUA <br />pump station operations and control schemes, and Identified off-site improvements that would <br />increase the operational capabilities of their existing distribution facilities. The WUA expanded the <br />scope of the PP2 Replacement Project to incorporate these improvements and also to upgrade <br />their Supervisory Control and Data Acquisition (SCADA) system at all of their facilities. <br />The final design of the PP2 Replacement Project addressed several different critical design <br />issues, including mitigating the potential for liquefaction resulting from a seismic event using an in- <br />situ soil remediation system, developing a pumping facility layout that makes the potential future <br />conversion from electric motors to gas engine -driven pumps possible, ensuring that the operation <br />of the new facility continued to meet all existing water quality requirements of the State of <br />California's Division of Drinking Water (DDW), and developing a comprehensive five -phase <br />construction program to ensure continuous water supply for WUA throughout the project. <br />Michael Baker Identified off-site Improvements to increase operational capability of existing <br />facilities; evaluated pump station and control schemes; provided hydraulic analysis; and <br />performed structural and electrical engineering, surveying, and mapping. Michael Baker also <br />provided final plans, specifications, and estimates (PS&E); CEQA compliance (notice of <br />exemption); and construction management and inspection. <br />Completed in February 2016, the new Pumping Plant 2 Facility was re -dedicated as the Marshall <br />R. Bowen Pumping Plant and includes a 18.9 -MGD pump station with 17,500 gpm of pumping <br />capacity to enable WUA to pump during off-peak periods and reduce power costs; two 2.2 -MG <br />above -grade steel reservoirs to serve as the forebay and provide operational storage; a 6,400 - <br />square -foot pump building, including office space for water production and pumping plant <br />personnel; new piping and control valves at off-site reservoirs; and upgraded SCADA and radio <br />communication facilities throughout the entire WUA service area. <br />C3233MI—_ <br />INTNNNATIONAL 15 <br />25B-37 <br />
