Not all types of waste can be filtered out during the treatment process, which is why our Industrial Waste Program is in charge of preventing pollution from entering the wastewater system in the first place.
City Soil Farm, located at King County Wastewater Treatment Division South Plant is a small farm that produces food for the community and demonstrates the benefits of turning wastewater into valuable resources like recycled water and Class A biosolids.
We have some of the largest wastewater treatment plants in the country. It takes a decade or more to build large wastewater projects, so it’s important we plan ahead. That’s where our planning staff and programs come in.
King County is working to control our combined sewer overflows through several strategies. One way we're reducing CSOs is through natural drainage solutions, also known as green stormwater infrastructure, which use plants, trees, and soil to soak up the rain.
As the days get shorter and we anticipate more rain in our forecast, we are celebrating a timely milestone—we just mailed our 1,000th RainWise rebate check in one of the eligible combined sewer overflow basins!
