Environmental Services will construct a sewer replacement project in the Slabtown district in northwest Portland. This project will replace and upsize about 8,400 feet (more than 1 and a half miles) of sewer main in streets, some of which are more than 125 years old and deteriorating due to age. They will repair pipes that connect properties to the sewer system, replace stormwater inlets and inlet pipes, and repair or replace more than 46 manholes throughout the project area.
