Below is a snapshot of current funding opportunities that help achieve state goals and priorities for increased water and energy efficiency and greenhouse gas reductions.

2018 Integrated Regional Water Management Grant Program

Administered by DWR, Round 1 of the IRWM Implementation Grant provides funds for projects that support statewide priorities and contribute to regional water self-reliance. These projects may include water reuse and recycling for non-potable projects, water-use efficiency and water conservation, groundwater recharge projects, capture and treatment of rainwater or stormwater, water desalination, and projects that improve water quality (e.g. drinking water treatment, groundwater aquifer remediation). 10 percent of grand funds are reserved for projects that directly benefit disadvantaged communities (DACs).

Water Recycling Funding Program- Pilot Project Grants

The SWRCB provides funding for the planning, design, and construction of water recycling projects that offset or augment state fresh water supplies. The Pilot Project Grants will assist public agencies in the construction of pilot projects for new potable reuse. These projects must develop new information to increase the knowledge and understanding of innovative applications of new and current technologies.

Grant Guidelines

ADMINISTERING AGENCY State Water Resource Control Board's Division of Financial Assistance
FUNDS AVAILABLE Eligible project can receive grant funds up to 35% of actual eligible pilot study construction costs incurred up to a maximum of $1 million.

Water Recycling Projects are funded through grants and loans from the following sources:

  • The Safe Drinking Water, Clean Water, Watershed Protection, and Flood Protection Act (2000 Bond Law, Proposition 13). This source primarily provides funds for water recycling facilities planning grants.
  • The Water Quality, Supply, and Infrastructure Improvement Act of 2014; (2014 Bond Law, Proposition 1). Proposition 1 provides grant and low interest financing for water recycling projects.
  • The Clean Water State Revolving Fund Program provides low interest loans.
MATCH REQUIREMENTS At least 50% of local cost share match must be provided but may be provided using CWSRF financing.
ELIGIBLE APPLICANTS Local public agencies, 501(c)(3) nonprofit organizations qualified to do business in California, public utilities, federally recognized Indian tribes, state Indian tribes listed on the Native American Heritage Commission’s California Tribal Consultation List, and mutual water companies.
  1. Must offset or augment state fresh water supplies.
  2. The pilot project MUST develop new information that does not currently exist and increase the body of knowledge regarding technologies that help the understanding of how potable reuse can be effectively achieved through the innovative application of current and new technologies.
  3. Have adequate and complete environmental documentation (CEQA).
  4. The total eligible project capacity shall be delivered within 5 calendar years of operation from the date of Initiation of Operations.
  5. Applicant must deliver no less than 25% of the eligible project capacity within the first calendar year of operation.
