City Sewers Completed Construction
Eagle Rock Interceptor Sewer
In January 2004, the City of Los Angeles Department of Public Works began building the Eagle Rock Interceptor Sewer (ERIS) in the Glassell Park, Highland Park, and Eagle Rock area. The three-mile long sewer cost about $20 million and was completed in summer 2006.
ERIS is a 12 to 48-inch diameter pipe that was microtunneled and trenched. It runs northward from San Fernando Road and Eagle Rock Boulevard then branches into two lines, ending at Eagle Rock Boulevard and Fairpark Avenue and the vicinity of Avenue 51 and York Boulevard.
In the past, spills occurred when water seeped into the old sewers through cracks and holes, overloading the system and forcing wastewater out through maintenance holes and onto the streets. This has been an acute problem during heavy rains. ERIS eliminates sewage spills in these neighborhoods by providing additional capacity that keeps the sewage contained.
