Californians used 10.4% less waterOpens in a new tab. in July as part of the state’s efforts to deal with the drought.  As the state faces a hotter, drier future and ongoing extreme drought conditions, the Department of Water Resources (DWR) is offering $6 million in financial assistance to support desalination projects that will help develop new sources of local water supplies in California.

Funded by Proposition 1, the Water Desalination Grant ProgramOpens in a new tab. is offering $6 million to support construction and design pilot projects that desalinate naturally occurring brackish and ocean water for potable water supply. Desalination is the process of removing salts and minerals from brackish water and seawater to produce water suitable for consumption, irrigation, and other supply needs.

“Desalination remains a critical water supply source in communities where traditional water supplies are limited,” said Karla Nemeth, DWR Director. “California faces a range of water supply challenges and climate change continues to intensify impacts and weather extremes. Our priority is building water resilience through a set of actions that will prepare our water systems to support our growing state in a hotter, drier climate.”

Funding request applications must be submitted by October 5 using DWR’s online submittal tool, GRanTS.Opens in a new tab. DWR expects to announce the final awards in February 2023. Eligible applicants include public agencies, mutual water companies, nonprofit organizations, and Tribes. Interested parties can find more information about the funding and eligibility requirements in the Proposal Solicitation Package.

This funding supports actions identified in the Governor’s recently announced strategy document, “California’s Water Supply Strategy, Adapting to a Hotter, Drier Future.Opens in a new tab.” The strategy outlines a series of proposed actions to help replenish California’s water supply and make our system more resilient, which includes capturing stormwater and desalinating ocean and salty water to help diversify supplies.

The state reports that to dateOpens in a new tab., DWR has awarded over $81 million in Proposition 1 desalination grants ranging from over $100,000 to $10 million to 17 projects. In addition to supporting local desalination efforts, DWR contributed $16 million to the National Alliance for Water Innovation (NAWI) in 2021 to help advance desalination research. Led by the Lawrence Berkeley National Laboratory, NAWI and its team of 180 institutions are conducting a five-year research project to lower the cost and energy required for desalination. The research will also improve brine management, increase longevity of system components, and develop methods to optimize operational efficiency. It is hoped that the benefits realized in the desalination industry will support other industrial sectors.
