Phase One. During phase one of the upgrade, a new 5,300-foot-long, 24-inch-diameter pipe was installed from the Bellevue Pump Station directly to the Eastside Interceptor, a large regional pipe near Interstate 405. The force main project was completed in March 2008.

Phase Two. Over the next two years, the above grade pump station will be demolished and replaced with a facility featuring more powerful pumps, a new generator building, stronger odor control equipment and updated architecture.

Upon completion, the refurbished pump station will be able to convey more than 13 million gallons of wastewater daily from west and central Bellevue to King County's South Treatment Plant in Renton -- a 60 percent increase in capacity.
