Thurston County Storm and Surface Water Utility

Protecting our Water Resources

Stormwater pollution from urban runoff can be a serious health risk and significant environmental threat to the quality of our rivers, lakes and streams. Every time it rains, pollutants such as sediment, oil, antifreeze, fertilizer, pesticides and animal waste are washed into storm drains and ditches, which then typically drains directly to a local water body, or into the ground -- our source of drinking water. 

The Thurston County Storm and Surface Water Utility provides programs and projects to reduce flooding, erosion and pollution caused by stormwater runoff, while protecting and enhancing aquatic habitat.
