PROPOSAL Civic. CenterStoramater Lift Station Renovation Design Services Whittier Pumping Plant No. 2 Replacement Project I Pico Rivera, CA Client: City of Whittier, 13230 Penn Street, Whittier, CA 90602-1772 Reference: Mr. David Pelser (former Director of Public Works for City of Whittier, now with Meridian Service Metropolitan Water District) (562) 298-8476, DavidCa mrmetro.org Year: 2016 Team Member Involved: John Nagle (Project Manager), Marek Przywara (Electrical Engineer), Sal Sheikh (Structural Engineer), Fabio Sanchez -Duran (Structural Engineer), Jerome Ruddins (Construction Management) Michael Baker provided design engineering services and construction phase support, including full-time construction management and inspection services, for the Whittier Utility Authority's (WUA) Pumping Plant No. 2, which was originally constructed in the 1930s. During the preliminary design phase, Michael Baker conducted a comprehensive hydraulic analysis of WUA's water supply and distribution systems, reviewed WUA pump station operations and control schemes, and identified off-site improvements that would increase the operational capabilities of their existing distribution facilities. The WUA expanded the scope of the PP2 Replacement Project to incorporate these improvements and also to upgrade their Supervisory Control and Data Acquisition (SCADA) system at all of their facilities. The final design of the PP2 Replacement Project addressed several different critical design issues, including mitigating the potential for liquefaction resulting from a seismic event using an in- situ soil remediation system, developing a pumping facility layout that makes the potential future conversion from electric motors to gas engine -driven pumps possible, ensuring that the operation of the new facility continued to meet all existing water quality requirements of the State of California's Division of Drinking Water (DDW), and developing a comprehensive five -phase construction program to ensure continuous water supply for WUA throughout the project. Michael Baker identified off-site improvements to increase operational capability of existing facilities; evaluated pump station and control schemes; provided hydraulic analysis; and performed structural and electrical engineering, surveying, and mapping. Michael Baker also provided final plans, specifications, and estimates (PS&E); CEQA compliance (notice of exemption); and construction management and inspection. Completed in February 2016, the new Pumping Plant 2 Facility was re -dedicated as the Marshall R. Bowen Pumping Plant and includes a 18.9 -MGD pump station with 17,500 gpm of pumping capacity to enable WUA to pump during off-peak periods and reduce power costs; two 2.2 -MG above -grade steel reservoirs to serve as the forebay and provide operational storage; a 6,400 - square -foot pump building, including office space for water production and pumping plant personnel; new piping and control valves at off-site reservoirs; and upgraded SCADA and radio communication facilities throughout the entire WUA service area.
