Inland Empire Brine Line

  • The Inland Empire Brine Line was damaged around 11 p.m. Monday, June 13, by construction work at the intersection of Cajalco and Temescal Canyon roads, causing a leak. The Santa Ana Watershed Project Authority quickly stopped the leak, contained the liquid, repaired the pipe, and cleaned up the area. The leak posed no public health risk, overnight traffic disruption was modest, and the Brine Line is back in normal service.
  • In August 2014, SAWPA issued a notice inviting bids for construction of the Inland Empire Brine Line Reach V Rehabilitation and Improvement Project On October 21, 2014, SAWPA awarded the construction of the project to Charles King Company.  The total contract amount is $12,561,000.  A notice to construct was issued to the contractor in January 2015.  The construction duration is 14 months and is anticipated to be complete in early 2016.    Funding for the Project is through the California State Water Resources Control Board Clean Water State Revolving Fund Loan Program.
