How to report a spill

The number one cause of pollution in Washington waters is stormwater runoff. 

As rainwater flows into the nearest grated storm drain, it picks up pollutants such as fertilizers, dirt and leaves, pet waste, soaps, vehicle fluids, and litter. This now polluted stormwater then empties directly into the nearest stream, wetland, or swimming beach without any treatment. This is different than water in our toilets and sinks, which goes to a treatment plant before being discharged to Puget Sound. 

The City of Sammamish works hard to keep our streams, wetlands, and swimming beaches clean of pollutants by responding to spills. 

The City of Sammamish responds to spills 24/7. The number of spills we respond to each year has grown from three in 2012 to 62 in 2024. That doesn’t necessarily mean more spills are happening, but it does mean our community has become more informed and has notified us of more spills, which means we’re able to respond to and clean up more pollution. 

When in doubt, call it in.
