Polybutylene Service and Valve Replacements
CI 5688 & CI 5689
This project includes replacing existing water infrastructure that has been identified as needing replacement. Key elements include replacing existing water distribution valves, saddles, water meter boxes, and polybutylene service lines with copper tubing, along with the installation of cathodic protection. The project also includes the replacement of ¾-inch copper service lines, implementation of traffic control measures, and all associated work necessary to complete the project.
Polybutylene was the standard material used for water service lines installed in the 1970’s. However, due to frequent leakage/breakage caused by the old age and the nature of the material used, these Polybutylene service lines are being replaced with new copper lines in an ongoing citywide program.
These valves are over 35 years old, most cannot be opened and closed fully, and in some cases are not operable at all. Replacement of the valves allows the mainline shutdowns required maintenance for residential service lines.
Impacted neighborhoods
Residents affected by the work will be those in the neighborhood bordered by Olsen Road, Pederson Road, and Northwood Parkway for the Poly Service Replacements, and those along Calle Castaño, Calle Fresno, Calle Quebracho, Calle Cedro, Calle La Maida, Calle Lacota, and Calle Arino for the Valve Replacements in Thousand Oaks.
