Funding Opportunities:

Supporting Innovation

The amount of water we have on Earth remains fairly constant.  It is used and reused and recycled.  There are no “untapped” supplies of fresh water.  Stretching the use of our limited water supplies requires a lot of creativity.  To support these efforts, Metropolitan has several incentive programs aimed at testing and developing different ways to conserve and extend the water we have available.

Local Resources Collage

Local Resources Program

The Local Resources Program is the linchpin for Metropolitan’s in-region supply development. The LRP encourages and accelerates projects to recycle water, treat degraded groundwater and desalinate seawater by offering direct incentives based on the amount of water produced. The projects help reduce demand for imported water supplies and increase water supply reliability regionwide. We currently fund a total of 116 projects across Southern California.

Applications are accepting on a rolling basis; member agencies can apply anytime as long as the program is active.

Incentives for Business:

Water Savings Incentive Program

This program offers funding for commercial, industrial, agricultural and large landscape projects that reduce water use.  Project funding is based on the quantity of water saved.  Incentives go as high as $0.60 per 1,000 gallons saved annually over the project life, with a maximum of 10 years.  More than 125 projects have been funded by Metropolitan through the WSIP.

Projects that qualify include:

  • Installation of commercial or industrial high-efficiency equipment
  • Industrial process improvements
  • Agricultural and landscape water efficiency improvements
  • Water management services


Please submit applications well in advance of your anticipated project start date. This will allow time for us to review the project for eligibility, have any questions answered and approve funding before your project begins. Funding for this program is limited and applying does not guarantee payment. Incentives are reserved for projects on a first-come, first-served basis until funding is exhausted.

One Water Awards Program

The One Water Awards Program is a water-efficiency awareness campaign to encourage businesses and other non-residential industries to participate in the Water Savings Incentive Program. A special awards ceremony celebrated past participants and leaders in the commercial, industrial, and institutional sectors who have achieved incredible water-savings through their funded projects. Their projects are located throughout the six-county service area and were recognized for their technological innovations, environmental stewardship and water sustainability. The recorded event and honoree videos can be found here

On-site Retrofit Program

Metropolitan’s On-site Retrofit Program provides financial incentives directly to public or private property owners in Metropolitan’s service area to convert imported water irrigation or industrial water systems to recycled water service. Incentives of up to $195 per acre-foot for ten years of estimated water use are available, with a cap at the actual retrofit costs. Items eligible for incentives include project design; permitting; construction costs associated with the retrofit of imported to recycled water systems; connection fees and required recycled water signage. Systems that are already under construction are NOT eligible for funding.

The program works on a first-come, first-served basis. Applications are accepted until funding for this program is exhausted. Once an application is reviewed and approved, applicants receive a notification that includes an estimated incentive amount along with a list of deadlines that must be met to qualify for funding. Incentive payments are made when all invoices and eligible costs are verified and the connection and use of recycled water becomes operational. If a project is disqualified, applicants may re-apply as long as the project is not under construction.

Supporting Research:

Future Supply Actions Funding Program

As part of Metropolitan’s long-term One Water resource strategy, this funding program promotes technical advances to better prepare the region to adapt to future water supply uncertainties. Since the program’s initiation, a total of $6.5 million has been awarded to Metropolitan member agencies. The program has helped fund more than two dozen technical studies and pilot tests exploring innovative approaches to local water supply development in Southern California. Awards have been given to studies in the areas of recycling, groundwater, seawater desalination and stormwater. 

The 2023 FSA funding round is closed. Awarded proposals will be posted in spring 2024. Completed project reports and webinar recordings for the past round of Future Supply Actions Funding Program studies are available below.

Innovative Conservation Program

Metropolitan is always looking for great ideas and ways to save water. This research-focused grant program, in collaboration with the Southern California Gas Company, allows us to form partnerships with public and private organizations to evaluate the potential and reliability of innovative water-saving devices, technologies and strategies. 

The program operates on a two-year cycle. The final reports for 2022 projects will be posted by fall 2024. We are expecting the next round of funding to be available in early 2025.

Community Outreach

Sprinkled throughout Metropolitan’s six-county service area are pockets of learning – conservation demonstration gardens, native garden tour stops, school programs and community workshops all designed to teach about the importance of water.

Their common thread is funding received through Metropolitan’s Community Partnering Program, which provides up to $3,000 in sponsorships to community-based organizations including nonprofits, professional associations, educational institutions and public agencies. Eligible projects include water-related educational outreach programs like community forums, workshops and water festivals, water-themed curriculum and supplies for grades K-12, after-school programs, exhibits, promotional materials and native plant and California Friendly® garden signage.

Applicants who serve our disadvantaged communities – which represent about half of Metropolitan’s service area – are especially encouraged to apply for sponsorships. 

MWD will be accepting applications starting in July 2024.
