San Diego County Water Authority committee hears Pipeline 6 study results

From the Fallbrook Village News:

The San Diego County Water Authority’s Water Planning committee heard the results of a Pipeline 6 feasibility and alignment study during a special May 14 meeting.

In addition to evaluating preferred alignments, the study identified major system integration and timing issues for the implementation of Pipeline 6.

Pipeline 6 is expected to carry between 470 and 630 cubic feet per second (cfs) of water and would connect Lake Skinner in Temecula with the County Water Authority’s Twin Oaks Diversion Structure. The 470-630 cfs rate equates to 300-400 million gallons per day (mgd), which would increase the CWA’s imported water pipeline capacity by 45 percent. Pipeline 6 is expected to be an untreated water pipeline, which would allow the conversion of an existing untreated water pipeline to a treated water pipeline and increase treated water capacity from about 600 cfs to 900 cfs and untreated water capacity from less than 800 cfs to about 1,000 cfs.

Pipeline 6 was initially proposed in 1987, and in 1993 the Metropolitan Water District of Southern California and the County Water Authority jointly prepared and certified an Environmental Impact Report. Shortly after the EIR was certified, work on Pipeline 6 was suspended due to updated water demand projections and the higher priority of other projects.

The total length of Pipeline 6 would be approximately 32 miles. The north reach of Pipeline 6 serves Temecula and covers the first seven miles between Lake Skinner and Anza Road. That segment was opened in late 2006.

The southern portion is expected to be needed between 2018 and 2023 if the Camp Pendleton desalination plant is not built.
