Staff at our King County wastewater treatment plants do an excellent job of cleaning wastewater, but not all types of waste can be filtered out during the treatment process. Our Industrial Waste Program is in charge of preventing pollution from entering the wastewater system in the first place.

That’s also where local business can make a difference. By making sure that they only send wastewater to the County system that meets the standards set to protect the environment, businesses play a big role in keeping our waterways clean.

Clean Water Awards recognize businesses for their efforts

Every year, King County’s Industrial Waste Program recognizes industrial wastewater dischargers that meet or exceed their wastewater discharge permit requirements with Gold, Silver, and Commitment to Compliance awards. These award winners are recognized for their work to help protect public health and the environment by controlling the discharge of harmful substances, preventing damage to our wastewater treatment infrastructure, and maintaining the quality of our recycled resources.

This year, 57 local facilities earned environmental awards for their dedication to business practices that protected regional water quality in 2021. The 37 gold, 20 silver, and 2 Commitment to Compliance awards earned last year recognize business efforts to protect communities, the environment, and the economy in our region. Visit our rewards and recognition program website to learn more about the criteria for the awards.
