The WaterWorks Grant Program provides approximately $5 million in funding every two years to organizations carrying out a variety of water quality improvement projects in the service area for King County's regional wastewater system. Nonprofits, schools and educational institutions, cities, counties, tribes, and special purpose districts are all eligible to apply—and partnerships are encouraged.

There are two different tracks for applying for grants: the competitive track and the council-allocated track. Both tracks have the same eligibility criteria, but the application and selection process are different. Proposals for the council-allocated track are selected by King County Council.* WaterWorks staff administer all grants after they are awarded, and all grants have the same reporting requirements.

*Contact your councilmember’s office directly for questions about the WaterWorks council-allocation review or selection process. For a map of council districts and contact info, visit the council district finder.
