Report
Summary
Phase I of this project is to implement standby power systems at Phase I facilities including the Cave Creek Corridor Booster Pump Stations (6A-B1, 7A-B1, and 8A-B1), the Union Hills Water Treatment Plant (WTP) pressure zone 5E, and the Deer Valley WTP pressure zones 1, 2A, and 3D finished water booster pumps. This project will also develop a roadmap for implementing power redundancy in future phases to maintain potable water production at the Union Hills, Deer Valley, 24th Street and Val Vista WTPs. Providing power redundancy at these facilities will improve the City's ability to continue potable water deliveries to customers during potential local or regional utility outages.
