The Water Authority announced today that it is planning repair work on one of its pipelines just north of the San Diego River in a remote section of Mission Trails Regional Park. The purpose of the work is to repair a few 24-foot sections of pipe, which are showing signs of deterioration. Construction is anticipated to begin as early as late January and last approximately one month.
In September 2007, the Water Authority began receiving notifications by a state-of-the-art, remote monitoring technology that sections of Pipeline 4 were deteriorating. In December 2007, Water Authority staff noticed the rate of deterioration was increasing and began making plans to repair the sections of pipe. The technology and how the Water Authority uses it to monitor its pipelines is being watched closely by many public water utilities around the world.
Since the San Diego River is flowing too high to allow construction traffic to cross it from Mission Gorge Road, construction traffic will need to enter the park from Calle de Vida in the community of Tierrasanta. All park trails are anticipated to remain open during the repair work.
A 14-day, 24-hour-per-day pipeline shutdown will mark the beginning of construction. The shutdown is necessary to stop the delivery of water in order to replace the deteriorated sections of pipe. After the shutdown, the pipeline will be brought back online to resume deliveries of water to member agencies. During the shutdown, construction will be 24-hours per day. The remainder of the work after the shutdown will be during normal work hours, 7 a.m. to 5 p.m., Monday through Friday.
Water will continue to be delivered to member agencies either until the pipe needs to be shutdown for the work or the pipe deteriorates to a point that it needs to be shutdown and repaired immediately. This work will not impact delivery of water to your home or business.
After the work is complete, the Water Authority will revegetate and restore the construction work area. The Water Authority will also restore any park trails that were damaged during use by construction traffic.
The Water Authority will continue to keep Tierrasanta, San Carlos, and the Mission Trails Regional Park Citizens’ Advisory Committee and Task Force informed as construction progresses.
