We protect public health and enhance the environment by treating and recycling wastewater.
In the 1950s, wastewater flowed largely untreated into Lake Washington and Puget Sound and many rivers and smaller lakes, fouling water and making a sullied mess of local beaches. In 1958 the voters created Metro and developed a regional wastewater treatment system based on watersheds as opposed to political boundaries. Shortly after Metro was formed, construction began on the county's two existin

🚫 Stop Flushing Wipes! 🚫
Even wipes labeled as “flushable” should be tossed in the trash. Wipes DO NOT breakdown in water. They form into a ball, clog pipes, and damage wastewater treatment systems. Don’t flush trouble—keep wipes out of your pipes, and flush only toilet paper!

Attention trail enthusiasts! If you frequent the hiking trails at the Brightwater Treatment Plant, we need your help. Alpha Hill, the hill that towers over the south part of the Brightwater trails area, is permanently closed for restoration. Please stay on the designated trails to protect the surrounding landscape. Informal paths on the steep hillside can harm water quality by sending dirt into Little Bear Creek, a home to endangered salmon.
Plan your next visit using our designated Brightwater trails map, offering three miles of routes for you to enjoy.

The future is looking bright at the Georgetown Wet Weather Treatment Station, where 182 solar panels will soon find a home.
Thanks to the community decarbonization grant through the state’s Climate Commitment Act, we’ll install a large solar array to reduce our reliance on the electric grid that will allow us to treat combined stormwater and wastewater while minimizing our greenhouse gas emissions.
Thank you to Governor Jay Inslee, Washington State Department of Commerce and Dow Constantine, King County Executive for paying us a visit to celebrate the great news!

We are soaking up this sunshine and loving the longer days.
Remember to stay hydrated. Drink plenty of water throughout the day, especially if you’re spending time outdoors. Dehydration can happen quickly! 🚰🧊

Big news for sustainability at King County Wastewater Treatment Division! The $200,076 community decarbonization grant from the state's Climate Commitment Act will allow us to install approximately 182 solar panels at our Georgetown Wet Weather Treatment Station, significantly reducing energy consumption as we continue to protect water quality!
Commerce today announced $72.6 million in grants for 71 community clean energy projects across Washington that advance environmental justice and equity. The funding from the state’s Climate Commitment Act will benefit communities in 24 counties through solar projects, hydrogen fueling, electricity microgrids and more.
This afternoon, Governor Jay Inslee, Dow Constantine, King County Executive and the Duwamish River Community Coalition joined Commerce team members for a tour of the Georgetown Wet Weather Treatment Station in Seattle to announce the funding. The facility helps control, treat, and disinfect up to 70 million gallons per day of combined stormwater and sewage that previously overflowed, untreated into the Duwamish River during heavy rains. With a $200,076 grant, the facility will install a large solar photovoltaic array onsite to help offset the increased energy use by the UV disinfection treatment technology.
All of the projects receiving grants had to include an environmental justice angle, meaning they had to benefit the people most impacted by climate change, who are typically lower income and people of color.
“These awards get money into the hands of people who can immediately put it to use fighting climate change,” said Commerce Director Mike Fong. “These communities were empowered to use their own discretion to create projects that meet their needs, which will improve outcomes for everyone in Washington.”

Thank you, Seattle Public Utilities, for sharing our progress on the Ship Canal Water Quality Project with King County Councilmember Claudia Balducci this week. Here we are at the Ballard shaft where a large pump station will send polluted water stored in a giant underground tunnel to our West Point Treatment Plant after heavy rains. The project will prevent 75 million gallons of polluted water from entering local waterways each year!

The sun-soaked roof on top of the new battery building at West Point Treatment Plant is the latest location where WTD is adding solar power! West Point's 140-panel solar array will power lighting and HVAC for the battery building and make a dent in King County's climate goals of 1.5 megawatts of solar by the end of 2025.
Wastewater treatment is energy-intensive, so we're tucking solar power into our operations to lower our greenhouse gas footprint.
Check out our blog for more details about our upcoming projects!

Happy Bike Month!
You might not guess it, but the bicycle plays a big role in helping move staff around our massive treatment facilities.
Our treatment plants cover a combined 260 acres and have a complex network of tunnels below them. Many folks use bikes to get around efficiently and sustainably!
Whether you are riding 30 feet below ground on your way to check a valve or taking a leisurely spin around the neighborhood, may your bike bring you joy today and every day.
