Working for clean water

We take the “waste” out of wastewater, but our job is much more than that. 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. Our 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.
