Community Report
This Wastewater Treatment Division report shares information about the services we provide, and explains the sewer rate and capacity charge to operate and maintain our regional treatment facilities.
Our regional wastewater treatment system has a big job to do. Not only does it operate around the clock to sustain a healthy environment, this vital infrastructure supports economic development that enables our region to thrive.
To keep the system operating reliably as our population grows, King County will need to continue investing in system upgrades and improvements.
We hope this report increases your understanding of our utility’s commitment to fiscal and environmental stewardship. We appreciate the opportunity to serve you and welcome your questions and comments.
