King County needs a strong economy and a clean environment. King County Industrial Waste Program supports both.

We administer regulations to make sure the wastewater generated by industries is treated properly. Many industries must pretreat wastewater before sending it to the sewer. This protects the wastewater treatment process, workers, facilities, and water quality.

And it works. Our waterways are cleaner today than in previous decades because business practices have improved.

Business survey update

Thanks to the 6000 businesses who participated in the recent business survey. The survey is now closed. In 2016 and 2017, King County may contact individual businesses based on the information they provided in the survey.
