PROJECT DESCRIPTION 

  • Residents affected will be in the areas of Conejo Oaks tract and north of Avenida de los Arboles between Mountclef Blvd. and Moorpark Road in Thousand Oaks

  • The work includes complete replacement of existing valves, saddles, water meters boxes, polybutylene water services with copper tubing and installation of cathodic protections, replacement of ¾” copper service line, traffic control, and all appurtenant work to complete the project. 

PROJECT TIMEFRAME

  • November 1, 2021- May 2022
  • 180 Calendar Days

     

BUDGET/FUNDING 

  • Construction contract has been awarded to J. Vega Engineering, Inc. from Camarillo, CA in the amount of $1,857,781.
  • The Project was funded in the Adopted FY 2021-22 Water Fund Capital Budget

     

PROJECT HIGHLIGHTS/BENEFITS

  • 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. 
  • The City acquired the water system at the Conejo Oaks track from California-American Water Company in 2006. In the Conejo Oaks tract area, cast iron saddles, installed in 1959, connect the water service laterals to the main lines. These saddles are prone to corrosion issues that cause frequent failures of the connections and high potential failure due to vibrations during paving construction.
