Euclid Avenue Backline Sanitary Sewer Rehabilitation and Replacement Project

Euclid Avenue Backline Sanitary Sewer Rehabilitation and Replacement Project

The proposed project consists of the rehabilitation of an existing sewer pipeline and facilities within the residential backyard area of Euclid Avenue, south of Regal Road. The project includes the replacement of manholes and the replacement of a sewer pipeline that extends through two aerial crossings spanning a perennial drainage. The proposed rehabilitation will improve capacity and alleviate any potential concerns of pipe failure along the aerial crossings. The existing pipeline and facilities are located in uplands, and rehabilitation will occur within the existing alignment. Pipeline replacement will be implemented through a combination of pipe bursting (trenchless installation) and open cut construction. The sewer pipeline rehabilitation will include new 8-inch HDPE pipe and the aerial crossings will be encased within a steel casing. New pier supports for the aerial crossings sections will be installed in uplands on either side of the perennial drainage, and the pipeline will span the full width of the drainage. Existing aerial crossing supports consist of wood and metal scaffolding that is anchored in concrete footings. The wood and metal scaffolding will be cut off at ground level and the footings will be abandoned in place. No excavation will be required to remove the existing support footings. No fill will be placed within the jurisdictional limits of the perennial drainage. The construction of these improvements will conform to existing City of Berkeley standards. All construction will occur in uplands above the Ordinary High Water Mark of the perennial drainage.
