We are your clean water agency!

Maintenance staff

In 1958, King County citizens established a regional wastewater conveyance and treatment system to clean the polluted waters of Lake Washington and Puget Sound. More than 40 years later, we have dramatically cleaned up the waters of our region. In partnership with other jurisdictions, businesses and individuals, King County continues to protect the public health and environment while recycling and reusing natural resources.

Learn more about our history.

We take the "waste" out of "wastewater," by recovering energy, producing a safe soil amendment, and reclaiming water for reuse!

To us, success means clean water. It means honoring our legacy while keeping a promise to another generation that our beautiful environment will be there for them to enjoy.

It also means being accountable to our ratepayers and operating a well-managed agency.

Division employees plan, design, build, and operate treatment facilities to clean wastewater before discharging it into Puget Sound.

Our employees also enforce regulations to reduce harmful waste discharged to the system, and we educate the public and businesses on ways to protect water quality.
