Construction in Auburn completed, road reopened
King County crews completed work to repair a sewer pipe on M Street NE in Auburn on May 15 and is completing restoration this week.
To protect public health and the environment, the King County Wastewater Treatment Division has repaired a section of pipe at the intersection of M Street NE and 2nd Street NE in Auburn. This pipe, called the M Street Trunk, was built around the 1950s and a section that was corroded by the hydrogen sulfide produced from wastewater was repaired.
Wastewater from south King County is collected by local cities and sewer districts and flows to the county’s South Treatment Plant in Renton.
What to expect
Construction to repair the pipe required an open cut in the road that temporarily closed the intersection of M Street NE and 2nd Street NE. Sewage diversion pipes were temporarily installed above ground to allow flows to bypass the section of pipe being repaired and reenter the sewer system at a maintenance hole on 2nd Street NE between M Street and N Street.
