Pump Out, Don’t Dump Out - Help protect Puget Sound!

Sam the Clam reminds boaters to do their part for cleaner waters

It’s boating season once again! Clean water is crucial for enjoyable boating. How boaters operate and maintain their vessels can significantly affect the health of Washington's waters.

The Puget Sound No Discharge Zone is part of this. When boaters remember to Pump Out, Don’t Dump Out, they help protect and restore Puget Sound.

We know the vast majority of boaters already practice good stewardship of our waters. What better way to show your support and enthusiasm for healthy waterways than helping us spread the “Pump Out, Don’t Dump Out message? There are many ways to get involved.

Most  marina pumpout stations are easy to access by both tenants and visitors. 

We appreciate the enthusiasm of public and private operators of boating facilites in promoting the Pump Out, Don’t Dump Out message and Pumpout Nav app to boaters.

Does your boating facility need resources like No Discharge Zone signs, social media posts, outreach ideas? We are happy to help!

​Why it matters

Raw or partially-treated boat sewage is highly concentrated and contains dangerous bacteria and viruses that are harmful to people and the environment. These pathogens impact water quality, beaches and shellfish beds. Eating contaminated shellfish can make people sick. The presence of bacteria and other pathogens can lead to the closure of beaches and shellfish beds that Washingtonians depend on for recreation, food and jobs.
