Project Update

The project consists of the replacement and realignment of an aerial 24-inch diameter ductile iron pipe (DIP) sanitary sewer line crossing the Slaughterhouse Wash. The existing sewer line is a 24-inch diameter DIP supported on cradles, mounted on steel columns with concrete foundations. The wash banks have eroded and previously placed rip rap has sloughed down into the wash bottom. This project proposes the replacement and realignment of the sewer crossing encased within a single span prefabricated truss bridge structure to eliminate the need for supports within the Slaughterhouse Wash Floodplain. Additional abandoned water and sewer utilities spanning the wash in this location will also be removed.
