Pacific Beach Pipeline

Pacific Beach Pipeline

The project is for the replacement and abandonment of approximately 42,794 linear ft (8.10 miles) of existing 8-inch, 12-inch, 16-inch, 20-inch, and 24-inch water mains and appurtenances constructed of cast iron (CI), asbestos cement (AC), polyvinyl chloride (PVC) and other existing material, installed as early as 1951. Associated water services and fire hydrants will be replaced. The project also includes the replacement and abandonment of 14,986 linear feet (2.83 miles) of 8-in, 12-in, and 14-in existing sewer mains constructed of concrete pipe (CP), vitrified clay (VC), and other material, installed as early as the 1950's. Associated sewer laterals and manholes will also be replaced. Construction methods would include open trenching with replace-in-place, replace in new parallel trenches, tunneling, rehabilitation via lining methods and abandonment within existing City of San Diego public right-of-way and City of San Diego water and sewer easements, and pipe replacement on the existing North Ingraham Street, South Ingraham Street, and West Mission Bay Drive bridges. The project would also include the demolition of the abandoned Pacific Beach Reservoir, located between Los Altos Road and Windsor Drive, backfilling and re-grading the reservoir excavation, and re-vegetation of the site with native or drought tolerant vegetation. The West Mission Bay Drive and Sports Arena Blvd Pressure Reducing Stations would also be relocated.
