Alternative means for Combined Sewer Overflow Control in the Murray basin, West Seattle
Location of alternative means for CSO control in Murray basin

In 2008, King County reported that the Murray CSO facility has five overflows per year on average that discharge a total of five million gallons into Puget Sound from the outfall off Lowman Beack Park. Alternative means being considered must be capable of managing a volume of about 1 million gallons of peak flows in order to meet regulatory requirements.

Information about proposed alternatives for CSO control projects in Murray is provided below, including some of the benefits and challenges King County has identified for each alternative.
