Wet weather resiliency
We are continually working to make our operations more resilient during winter storms in wet weather season, and making improvements at our West Point Treatment Plant.
We currently have major projects underway to improve our wastewater treatment system, including:
- Georgetown Wet Weather Treatment Station
- Ship Canal Water Quality (joint project with Seattle Public Utilities)
- North Mercer Island/Enatai Sewer Upgrade
