Water Desalination Grant Program (California)

Water Desalination Grant Program (California) is sponsored by California Department of Water Resources. This program provides grants for projects focused on brackish water desalination, contaminant and salt removal, and salinity management to enhance California's water and drought resilience. Funded projects support the planning and development of potable water for municipal uses.

Water Desalination Grant Program Water Desalination Grant Program Water Desalination Grant Program Proposition 4 Funds for Brackish Desalination Proposition 4, Section 91016, allocates $62. 5 million for brackish desalination projects.

DWR’s Water Desalination Grant Program plans to award grants through a competitive application process for projects focused on brackish water desalination, contaminant and salt removal, and salinity management to enhance California's water and drought resilience. The Program is developing grant guidelines to award funding and will release the guidelines as they become available.

Desalination Grant Program Background DWR provides grants to local agencies for the planning, design, and construction of projects to desalinate naturally-occurring brackish and ocean water for potable water supply. It also provides grants for pilot, demonstration, and research projects. Grant funding is from Proposition 50 (2004) and Proposition 1 (2014).

As of May 2024, over $123 million in grants ranging from $45,000 to $10,000,000 have been awarded to 65 projects. Between 2005 and March 2018, DWR conducted four rounds of grant funding. After the fourth round, the program was modified to a Continuous Application Process (CAP), which enables applicants to submit projects at any time when grant funds are available.

DWR then reviews applications and awards grants in batches . Grant Application Process The rules and procedures for funding vary depending on funding source, availability of funds, and DWR priorities at the time of funding. Each round of funding generally starts with the drafting of a Proposal Solicitation Package (PSP), which contains detailed grant funding program rules and procedures for that round of funding.

The PSP has a description of types of agencies that can apply, types of projects that can be funded, instructions for application, the proposal review process, and the criteria for proposal selection for funding. The draft PSP is issued for public comment. After adoption of a final PSP, the application period begins.

Applications received by the deadline are reviewed according to the selection criteria, and a draft list of proposals recommended for grant funding is released for public comment. Subsequently, approved projects are awarded funding. DWR uses an online application tool called GRanTS.

An applicant must register to establish an account in GRanTS. Detailed procedures are described in the PSP applicable to the current round of funding. Applicants of awarded projects must enter into a Funding Agreement (contract).

Grant disbursements generally occur after costs are incurred and are provided after review of expense documentation provided by the grantee with invoices. After project completion, there may be annual reporting for up to five years to describe briefly the results of the project. The first three funding rounds used funds authorized by Proposition 50.

The fourth round and subsequent Continuous Application Process used funds from Proposition 1 and 50. The Continuous Application Process has been suspended. DWR is not accepting applications at this time.

Additional information can be found below: Continuous Application Process Continuous Application Process Suspended At this time the Continuous Application Process has been suspended. DWR is not accepting applications at this time. DWR implemented the Continuous Application Process, referred to as CAP, in March 2018.

CAP uses the same submittal and review process described in the Round 4 Proposal Solicitation Package (PSP) and is supplemented with the Continuous Application Process Guidance . Applications are reviewed and qualified projects awarded on a first-ready, first-served basis until all available funds are awarded. To date, DWR has awarded over $123 million in grants funded by Proposition 50 and Proposition 1.

Projects funded by the Water Desalination Grant Program have included feasibility studies, research, design pilots, and construction projects to support the evaluation, development, and implementation of potable groundwater and surface water desalination projects in California.

Grants awarded from these funds are referred to as CAP6. Construction project generally consists of the design and construction of a full-scale permanent desalination facility and related infrastructure to result in an operable municipal water supply project. A construction project can include funding for design, but design will not be funded as a stand-alone project.

Construction projects that depend upon future phases for an operable facility are not eligible.

Design Pilot project is a small-scale prototype for a full-scale project or a full-scale component of a project and is intended to refine design criteria, aid site selection, or study particular technologies or methodologies (conventional or innovative) for the purpose of implementing an already proposed full-scale municipal desalination facility.

This fourth round of grant funding includes funding for 5 types of projects as follows (see the PSP for full descriptions of project types): Construction projects generally consist of the design and construction of a full-scale permanent desalination facility and related infrastructure to result in an operable municipal water supply project.

A Construction project can include funding for design, but design will not be funded as a stand-alone project. Construction projects that depend upon future phases for an operable facility are not eligible.

Feasibility Study projects are used to determine the need for a water supply project, to analyze the alternatives to meet the project objective, to determine whether a desalination project is the “preferred alternative”, and if it is, to identify the implementation steps for the project.

Environmental Documentation projects are stand-alone projects for compliance with CEQA or National Environmental Policy Act (NEPA) where the basic feasibility study has already been completed and there is a likelihood for initiation of a construction project. As a requirement for funding, the completed portions of the feasibility study must be submitted with the application.

Design Pilot project is a small-scale prototype for a full-scale project or a full-scale component of a project and is intended to refine design criteria, aid site selection, or study particular technologies or methodologies (conventional or innovative) for the purpose of implementing an already proposed full-scale municipal desalination facility.

Research Pilot projects are typically small-scale prototypes for a full-scale device, equipment, process, or other technology and are intended to advance the knowledge base of new desalination technology, related infrastructure, and by-products treatment and disposal.

End of 2017 Grant Funding (Round 4) In November 2002, California voters passed Proposition 50, the Water Security, Clean Drinking Water, Coastal and Beach Protection Act of 2002 (incorporated into Division 26. 5 of the California Water Code, beginning with section 79500 ). Section 79545(a) in Chapter 6 provided $50 million for grants for desalination of ocean or brackish water.

Sections 79547 and 79547. 2 in Chapter 6 have other conditions that apply to this funding. Subsequent to passage of Proposition 50, the California State Legislature passed “trailer bills” that contain additional requirements for implementation of Proposition 50.

Proposition 50, as passed by voters Division 26. 5 of the California Water Code , including trailer bill sections. In November 2014, California voters passed Proposition 1, a part of which is the Water Quality, Supply and Infrastructure Improvement Act of 2014 (California Water Code, Division 26.

7, Section 79700 et seq.) Chapter 9 of Proposition 1 (the proper legal reference is Chapter 9 of Division 26. 7 of the Water Code, Sections 79765-79768) provides $725 million for grants/loans for water recycling and advanced treatment, including desalination projects.

DWR’s Water Desalination Grant Program will incorporate the Proposition 1 desalination elements in Section 79765(b), (d), and (f). The portion of funds allocated to desalination is $100 million, 7 percent of which is reserved for bonds and program administration. Proposition 1 funding of desalination shall be administered consistent with Proposition 50 desalination programs administered pursuant to sections 79545 and 79547.
