Boating Pumpout

Clean Vessel Act


The federal Clean Vessel Act provides funds to help reduce pollution from vessel sewage discharges into U.S. waters. These funds come from taxes on the sales of fishing equipment and on recreational boating fuel. Washington State Parks makes grants to both public and private sector boating facility operators for the construction, renovation, operation, and maintenance of pumpout and dump stations for use by recreational boaters. The program also provides boater education to promote public awareness about boat sewage and its proper disposal.

Keeping the Waters Clean


In 2016, Washington boaters prevented 10,039,480 gallons of sewage from contaminating Washington's waters by using Clean Vessel Act pumpout facilities. A clean marine environment is very important for everyone to enjoy the beautiful bodies of water throughout Washington. Boaters can help keep Washington's waterways clean. Washington offers approximately 145 Clean Vessel Act funded disposal facilities with a variety of stationary and portable pumpouts that provide a convenient way to properly dispose of boat sewage. For additional convenience pumpout skiffs that can service boats right in their slips are also available in many marinas and on Lake Washington, Portage Bay and the Duwamish River.
