Hydropneumatic Tank Replacement Phase 3

The Coachella Valley Water District (CVWD) will replace two (2) existing steel hydropneumatic tanks at CVWD Booster Station 05505 (BS 05505) and 06730 (BS 06730) and rehabilitate one (1) hydropneumatic tank at CVWD Booster Station 06504 (BS 06504). BS 05505 (3,200 gallons) and BS 06730 (5,000 gallons) will be replaced with two (2) new 5,000-gallon tanks. The rehabilitation of BS 06504 will retain its 5,000-galon capacity. CVWD’s domestic water system relies on pressurized tank(s) to maintain domestic water pressure allows for booster pump(s) to cycle at appropriate intervals and reduces unnecessary over pumping during high demand. These three (3) tanks are in need of rehabilitation and replacement because the current tanks are deteriorating and corroding and run the risk of failure that can cause disruptions within the domestic water system. This project includes the manufacturing to fabrication of two new (2) hydropneumatic tanks (BS 05505 and 06730) and rehabilitation of one (1) hydropneumatics tank (BS 06504) using CVWD’s current system sizing parameters and coating specifications. Construction is anticipated for the duration of up to 280 calendar days and will start in September 2026. This project will require minimal excavation for the placement of structures and equipment. There will be no disruptions to water services during construction. BS 05505 is within the Santa Rosa and San Jacinto Mountains Conservation Areas and is subject to the CVMSHCP Conservation Measures and the CVWD established Operations and Maintenance manual. BS 05505 and 06730 are within the conservation areas of the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP); however, the sites are not subject to the CVMSHCP development mitigation fee because the sites are previously developed.
