How can a sewer pipe protect salmon? Ages ago when this pipeline was first put in, it seemed like a good idea to run it along the low point of Coal Creek in Bellevue. Nowadays, we are trying to do better for the environment. When construction starts on the Coal Creek Sewer Upgrade this summer, salmon habitat will be front of mind as we move 2 miles of active pipeline away from the creek and restore sensitive habitat areas for salmon. This project was designed to carry more wastewater and meet the growing needs of Bellevue and Newcastle. 

This is the first wastewater infrastructure project in the nation to receive Salmon-Safe certification, a leading eco-label. The popular hiking trail along the creek will also be improved for accessibility — creating better opportunities for people of all abilities to enjoy time in this special natural area.  

It’s all part of King County’s effort to deliver infrastructure projects that work for people, salmon, and the environment. To stay up to date, visit our project page. 

We’re celebrating 10 years of the Operator-in-Training (OIT) Program, a pathway into clean water careers in wastewater. Over the past decade, this nationally recognized program has helped fill more than 75 critical operator positions with local talent drawn from King County communities.  

This year brought in a record 630 applicants, with 12 trainees now working through their classroom and on-the-job training. A video about the program, produced by our in-house videographer, was just nominated for an Emmy. The program continues to grow, shaping the next generation of clean water professionals.  

Our region is growing, our climate is changing, and we're planning ahead so our wastewater system can meet the challenges of the future. King County is updating its long-term plan to protect water quality, public health, and the environment for generations to come.  

Your voice matters in this effort! We are collecting perspectives from across King County to inform our Vision for Clean Water — a roadmap that looks out 75 years and asks: “Imagine what’s possible if we get this right.” Your feedback will help us make decisions on critical investments in our wastewater infrastructure through the year 2100. Our online survey is open until June 23, 2025. 

We had a great time at the 44th annual Trades Fair at Seattle Center, hosted by the Washington Women in Trades. Our table was buzzing all day with curious minds, good conversations, and some pretty fun (and educational) games. Our booth even came in first place for the indoor exhibit category this year! 

One of the best parts? Seeing so many young people excited about careers in clean water services. Thanks to everyone who stopped by and spent a little time with us.

When you think about wastewater, you probably don’t think about paint. But painting plays a big role in keeping our system running safely and reliably. 

Wes Wilson is one of our industrial painters at West Point Treatment Plant. In this short video, he shows us how his work protects pipes, pumps, and equipment from the harsh, corrosive environment they operate in every day. Take a few minutes to walk the plant with Wes and hear why he takes so much pride in what he does.
