King County crews are on the scene of a brief sewer overflow at the 63rd Avenue pump station near Constellation Park on the south side of Alki, and officials are telling people to stay out of the water while they sort out what happened. Warning signs are going up along the shoreline, nearby residents are being notified, and anyone with questions can call the Wastewater Treatment Division’s incident hotline at 206-296-7432.
County says crews are on scene
According to the West Seattle Blog, the King County Wastewater Treatment Division called this a “brief sewer overflow” at the 63rd Avenue Pump Station in the 3500 block of Beach Drive SW, right by Constellation Park. The announcement did not say how much sewage got into the water or what triggered the problem, leaving those key details still to be determined.
Where to get official updates
The King County Wastewater Treatment Division says it will post updates and any guidance from Public Health – Seattle & King County on its incident‑response page. As noted by the King County Wastewater Treatment Division, Community Services staff are placing warning signs at public access points and will share lab results and next steps as they come in.
Past spills and enforcement underscore the risks
This stretch of shoreline has dealt with contamination scares before. In 2022, a side‑sewer discharge in the same general area led to posted health warnings and water sampling, as covered by the West Seattle Blog. More broadly, the Washington State Department of Ecology has penalized Seattle and King County agencies in recent years for combined‑sewer overflow violations, underscoring how seriously the state takes sewage in local waterways.
Practical advice for beachgoers and pets
Until officials give the all‑clear, skip the saltwater dip. Avoid entering the water, keep dogs off the shoreline, and do not harvest shellfish near Constellation Park. If you did come into contact with seawater in the area, rinse off with fresh water and check in with a medical professional if you develop any concerning symptoms. Visible sewage or strong sewage odors can be reported to the WTD incident hotline at 206-296-7432 or through the King County Wastewater Treatment Division.
