Central-Wheeler Tank and Systems Improvement Project
Sweetwater Authority proposes to construct a new 0.8 million gallon (MG) water storage tank and associated conveyance pipelines near Sweetwater Reservoir. The 2015 Water Distribution System Master Plan evaluated Sweetwater Authority’s transmission, pumping, storage and distribution network and made recommendations to meet anticipated demands through the year 2040. The current requirement to satisfy maximum day and fire protection water demands in the Wheeler Pressure Zone is 0.60 million gallons per day (MGD) and the projected demand is 0.84 MGD by 2040. The existing Wheeler Tank was constructed in 1952 and has an operating storage capacity of 0.36 MG, but operates at a reduced capacity of 0.25 MG since the tank does not meet structural stability requirements for seismic activity. The proposed Project would improve reliability of the water distribution system in the current Wheeler Pressure Zone and a portion of the Gravity Pressure Zone by allowing Sweetwater Authority to meet anticipated maximum day and fire protection demands through the year 2040. The project would involve construction of a new 0.8 MG welded steel water storage tank (Central-Wheeler Tank) near a hillside in an undeveloped portion of land owned by SWA and construction of associated water drainage and conveyance pipelines to improve reliability of water distribution within Sweetwater Authority’s Wheeler Pressure Zone and a portion of the Gravity Pressure Zone. Project facilities would occur within public rights-of-way, within property currently owned by Sweetwater Authority, or easements to be acquired by Sweetwater Authority.
