About water grants

Water grants fund drinking water, wastewater, watershed protection, and water quality work across the country. The U.S. Environmental Protection Agency (EPA) administers programs such as the Clean Water State Revolving Fund and Nonpoint Source (Section 319) grants, while USDA supports rural water infrastructure and NOAA and the National Fish and Wildlife Foundation fund coastal and watershed resilience. Eligible recipients range from municipalities and utilities to nonprofits and tribes.

A long list is the starting point, not the shortlist. Our grant prospecting guide shows how to narrow water grants down to the funders most likely to say yes, using their giving records.

Frequently Asked Questions

How much money do water grants award?

Of the 788 water grants Grantable lists as of October 5, 2026, 346 publish an award amount. The median listed award is $60K, and the middle half fall between $13K and $400K. The largest is $10M. Amounts are each grant's stated maximum, so a typical award can be smaller.

Which funders offer the most water grants?

By number of active listings, the leading funders are Natural Resources (26), Chesapeake Bay Trust (19), Maryland Department of the Environment (18), Lake Champlain Basin Program (16), and National Fish and Wildlife Foundation (16). In all, 349 funders have at least one active grant in this category.

When are water grants due?

Of 788 grants listed, 13 accept applications on a rolling basis, 47 have a published upcoming deadline, 39 run on a stated cycle (such as annual or quarterly) without a published date, and 689 don't publish a deadline, so check the funder's site. Among dated deadlines, 49% fall in October–December.

What grants are available for water projects?

Funding covers drinking water and wastewater infrastructure, watershed and source water protection, nonpoint source pollution control, and habitat and resilience work. The EPA's Clean Water State Revolving Fund and Section 319 grants are major federal mechanisms, alongside USDA rural water programs and NOAA coastal funding. Some assistance comes as low-interest loans rather than outright grants.

Does the EPA fund water quality work?

Yes. The EPA funds water quality through programs like the Clean Water State Revolving Fund, which supports wastewater treatment, nonpoint source control, and watershed management, and through Section 319 nonpoint source grants administered with states. Eligible recipients can include municipalities, nonprofits, and citizens' groups, though much CWSRF assistance is delivered as loans.

Who else funds watershed and water nonprofits?

Beyond the EPA, USDA funds rural water and wastewater systems, NOAA supports coastal and estuary work, and the National Fish and Wildlife Foundation funds watershed and resilience projects, often with required match. Regional programs like Chesapeake Bay and Great Lakes initiatives, plus state agencies and private foundations, round out the landscape. Many water projects braid several of these sources together.
