WaterWorks Grant Program

WaterWorks provides funding for projects that improve water quality in the service area for King County's regional wastewater system. This grant program complements the water quality mission of the Wastewater Treatment Division.

In addition to the WaterWorks competitive grants, water quality project funding is available through King County Council allocated funding. 

Approximately $2 million are awarded every two years for organizations carrying out a variety of projects. Non-profits, schools and educational institutions, cities, counties, tribes, and special purpose districts are eligible to apply, and partnerships are encouraged.
