The San Diego County Water Authority (SDCWA) will conduct an open house to discuss its Mission Trails to Lake Murray water pipeline relining project due to begin in August.

Background (reprinted from SDCWA’s website):

“In October 2008, Pipeline 4 failed in a fairly remote section of Mission Trails Regional Park, near the San Diego River. After the failure, the Water Authority performed forensic analysis on the pipe and determined that a short section of the pipe needed to be urgently relined with steel. Subsequently, from mid-February through mid-March 2009, the Water Authority relined approximately 1,200 feet of Pipeline 4 north and south of the San Diego River.”

“This relining project will reline the sections of Pipeline 4 that were not urgently relined. Generally, relining construction rehabilitates segments of pipelines based on their age and the need for improvements. The Mission Trails to Lake Murray Relining Project involves rehabilitating approximately 3 miles of Pipeline 4 beginning immediately south of State Route 52 in Mission Trails Regional Park east of the community of Tierrasanta and continues south to Lake Murray in the community of San Carlos. It also involves rehabilitating approximately a half-mile portion of Pipeline 3 along Lake Shore Drive, south of Jackson Drive, in the community of San Carlos and city of La Mesa.”

Additional detailed information about the project is available at SDCWA’s website.
