Document Description
Coachella Valley Water District (CVWD) proposes to replace (3) steel hydropneumatic tanks at existing CVWD Booster Station 05502 (BS 05502) and 08121 (BS 08121). (2) Tanks of the same size will be removed and replaced at BS 05502 and (1) tank of the same size will be replaced at BS 08121. The (2) tanks at BS 05502 will be replaced with a 5,000 and 11,000-gallon steel tank. The (1) tank at BS 08121 will be replaced with a 9,500-gallon steel tank. The water hydropneumatic system relies on the pressurized tank(s) to maintain domestic water pressure and allows for booster pump(s) to cycle at appropriate intervals and reduces unnecessary over-pumping during high demand. These (3) tank(s) are needed for 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 installation of new hydropneumatic tanks using CVWD’s current system sizing parameters and coating specifications, removing, and salvaging each of the (3) old tanks, and installing a new hydropneumatic tank(s) at the existing booster station sites.
Construction is anticipated to begin in Spring 2023 and will take approximately 180 days for the project to be complete; there will be no interruption to domestic water services during construction. The project will require minimal excavation activities and no road closures will be needed for all ground disturbance and construction activities would occur entirely within the previously developed booster station sites. Surrounding land uses around BS 05502 consist of residential, commercial, open space, and roadways and is not located within or adjacent to a conservation area associated with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP). BS 08121 is located in a rural residential area and is located on the Dos Palmas Conservation Area and is subject to the CVMSHCP Land Use Adjacency Guidelines for drainage, noise, toxics, lighting, and invasives. The sites are not subject to the CVMSHCP development mitigation fee because the sites are previously developed.
