Project description

King County built a million-gallon underground storage tank across the street from Seattle’s Lowman Beach Park to reduce combined sewer overflows (CSOs). The tank stores excess stormwater and wastewater that would otherwise overflow into Puget Sound when the Murray Pump Station exceeds maximum capacity. Learn more about this project

Project schedule

The Murray Wet Weather Facility began operating in November 2016. Project restoration was completed in spring 2017.
