Sewer and Water Main Replacement Group 781 Project
Project Background
The project consists of replacing portions of the existing vitrified clay (VC) sewer mains and existing cast iron (CI) water mains serving the community of Mid-City/City Heights. The existing mains were originally installed between 1920 and 1960 and are nearing the end of their service life.
Project Overview
Sewer and Water Group 781 will replace approximately 11,276 linear feet (2.14 miles) of existing 6-inch, 8-inch, and 10-inch sewer mains with 8-inch, 10-inch, and 15-inch PVC pipes. The project will also include the replacement of 7,435 linear feet (1.41 miles) of cast iron water mains with 8-inch, 12-inch, and 16-inch PVC pipes. The project area includes 29 properties that need replumbing work.
This project encompasses the area east of Euclid Avenue, west of 54th Street, south of Trojan Avenue, and north of Landis Street, as well as sewer main upgrade on Loris Street. Construction of the project will affect portions of the streets shown in the attached 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, a trenchless method of construction will be used.
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 $7,522,151.
