We are your clean water agency!
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 60 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.
As an employer, King County attracts and supports employees committed to making a difference in our community. The work we do—health and human services, law enforcement, courts, parks, wastewater, transportation—makes a real difference to our neighbors.
King County Wastewater Treatment Division is committed to protecting public health and enhancing the environment by treating and reclaiming water, recycling solids, and generating energy. Fulfilling our mission requires a diversity of employees to build, operate and maintain our facilities.
Our award-winning agency offers careers in a wide range of fields. Come join one of the premiere wastewater treatment agencies in the nation.
