Sewer and Water Main Replacement
Group 780 Project
Project Background
Originally installed in the 1950's, the sewer and water lines installed in the area are nearing the end of their service. The City of San Diego has established an ongoing program that mandates the replacement of all aging and deteriorating existing concrete sewer mains and existing cast iron water mains. These replacements will eliminate future sewer main stoppages, sewer spills and water main breakages, while bringing the existing sewer and water mains up to current City standards.
Project Overview
Sewer and Water Group 780 will replace approximately 12,900 linear feet (2.4 miles) of existing 6-inch and 8-inch sewer mains with 8-inch PVC pipes. The project will also include the replacement of 2,825 linear feet (0.5 miles) of cast iron water mains with 8-inch PVC pipes.
The limits of this project include two major areas. The first area is located north of El Cajon Blvd., within the College Area Community and includes Baylor Dr., Austin Dr., Atlanta Dr., Gilbert Dr., and Berting St. The second area is located south of El Cajon Blvd. within the City Heights Community, and includes 54th St., 53rd St., 52nd St., 51st St., and three alleys in the area as shown on the location map.
The majority of the project's construction work will occur within the public right of way, with the exception of a few segments that run in private easements. The open trench method will be utilized to replace the existing pipes and in certain conflict areas pipe rehabilitation will be applied.
Benefits
The purpose of the project is to improve service reliability, increase the size of existing pipes to better serve the area, reduce maintenance needs and minimize future water main breaks caused by aging pipes.
Construction of the project will reduce sewer spills and maintenance requirements, improve service reliability and upgrade the system to modern standards.
Cost
The construction contract is for $6,662,620.
