| Project Description
The San Diego County Water Authority's Pipeline Relining
program takes a proactive approach to pipeline maintenance. This 30-year
program focuses on one community per year, with a priority on those areas
where deterioration is most severe. This program ensures the reliability
of water supply to the region.
Relining is necessary because the pipelines showed signs of deterioration
and joint damage during internal pipeline inspections. Relining the existing
pipelines with steel is a quicker, more cost-effective alternative to
removing and replacing the pipelines. Just as important, relining significantly
reduces the impact of construction on nearby residents. The new steel
liners serve as new pipelines, and are expected to last approximately
50 to 75 years. Most relining work is done inside the pipe. Relining work
does not interrupt the delivery of water to nearby homes or businesses.
All relining activities, including excavation, temporary lay-down of
lining materials and vehicle parking, take place on the Water Authority's
existing easement. The Water Authority works hard to minimize the impacts
of relining activities to nearby residents, including noise, dust and
traffic. When relining is complete, the Water Authority's easement is
restored to its original condition.
