Approved Projects

As a Lead Agency for CEQA, Sweetwater Authority considers a project “approved” once the decision-making body has (1) reviewed and considered, in its totality, the project’s final environmental documents, and (2) decided to approve or carry out the project. The following projects have been recently approved by the Authority: 

Sweetwater Dam and South Dike Improvements Project

The proposed project would include improvements to the Sweetwater Dam and South Dike to safely pass and contain storm water flows associated with a Probable Maximum Flood (PMF) event. In order to achieve that primary objective, an existing parapet wall on the north side of the dam would be raised and a new parapet wall would be constructed on the south side. Additionally, the South Dike would be raised. Other minor repairs and modifications to the Sweetwater Dam, South Spillway, and associated facilities would also be conducted. The proposed project would fully comply with the California Department of Water Resources (DWR) Division of Safety of Dams (DSOD) regulatory program (California Water Code Division 3, Dams and Reservoirs).

Sweetwater Reservoir Wetlands Habitat Recovery Project


The Sweetwater Reservoir Wetlands Habitat Recovery Project is a habitat improvement action in support of the Sweetwater Reservoir Habitat Management Program, which provides management/conservation of habitat for the state and federally endangered least Bell’s vireo. The project would entail the comprehensive restoration of the riparian habitat at the confluence of the Sweetwater River and Sweetwater Reservoir, resulting in a self-sustaining ecosystem supporting high quality least Bell’s vireo habitat.

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.

Addendum to 2015 Urban Water Management Plan, Water Shortage Contingency Plan, and 2020 Urban Water Management Plan

Sweetwater Authority (Authority) has prepared an update to its Urban Water Management Plan (UWMP) in accordance with the California Urban Water Management Planning Act (Act) and the Water Conservation Act of 2009, commonly referred to as SBX7-7, and the guidance provided by the California Department of Water Resources UWMP Guidebook 2020.

The Act mandates that every urban supplier of water providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually, prepare, and adopt a UWMP and that the UWMP be updated and adopted at least once every five years on or before July 1, in years ending in six and one. UWMPs support a water suppliers’ long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs. 

Also, per the Act, the Authority has prepared an Addendum to its 2015 UWMP to demonstrate reduced water reliance from the Bay-Delta and a Water Shortage Contingency Plan (WSCP) as part of the 2020 UWMP. The WSCP discusses the Authority’s detailed plan on how the Authority will act in the case of water shortage conditions and describes six different levels of water shortage contingency.
