The Western Way Pump Station project consisted of hydraulic analysis and modeling for present and future water supply from the MWD 96″ Perris Valley Pipeline to the District’s 1627 and 1705 Pressure Zones, and pumping unit selection. The project was designed for initial operation with provision to add and change pumping units for future operation. The 1627 Zone was designed with six ultimate pumping units, five at 300 hp at 32,000 gpm initial capacity and six 500 hp pumping units at 58,800 gpm future capacity. The 1705 Zone was designed with three ultimate pumping units, two 60 hp pumping units at 1,800 gpm initial capacity and three 350 hp pumping units at 10,500 gpm future capacity. Project design also included a tilt‑up concrete pump building with bridge cranes, ultimate site layout for addition of standby power generation building, 18 pulse variable frequency drives for all pumping units, and design of electrical and control facilities for expansion to accommodate ultimate requirements.
Krieger & Stewart provided preliminary and final design services, which consisted of network modeling and hydraulic analyses, station capacity determination, pump selection, surge analyses, design survey, geotechnical investigation, record of survey, preparation of preliminary layouts, pre-negotiation of equipment, utility service design and coordination, noise impact study, preparation of contract documents, and preparation of construction cost estimates.
