AKM prepared a Preliminary Design Report as well as construction plans, specifications, and cost estimates for a new water booster pump station to replace the existing 60-year-old station, which was inadequate in capacity, difficult to access, and in poor condition.

The new pump station was constructed at the existing Simon Ranch Reservoir site and features two 850 GPM duty pumps, one 2,500 GPM fire flow pump, and a 500 kW permanent emergency generator. It also includes an inter-zonal connection through a pressure-regulating station, all housed within a below-grade reinforced concrete structure. The pumps are operated by 18-pulse variable frequency drives (VFDs) with bypass solid-state contactors, ensuring continued operation in the event of an outage of the Zone 3 reservoir.
The project also involved the installation of 4,100 linear feet of 8-inch, 10-inch, 12-inch, and 16-inch pipelines serving Zone 1 and Zone 3. As part of the design process, AKM utilized the City’s hydraulic model to evaluate various pumping alternatives, station layouts, surge analyses, control schematics, and zonal demands based on historical records. Additionally, AKM assessed various flow regulation systems to optimize pump station performance during storage reservoir outages.
