Water authority project set to rennovate underground pipelines

SAN DIEGO (CNS) – The San Diego County Water Authority is providing information on relining some three miles of pipeline under several San Diego and La Mesa streets and parts of Mission Trails
Regional Park.

The Mission Trails to Lake Murray Relining Project, set to begin next
month, is part of a $786 million multi-decade effort designed to extend the
service life of the 82 miles of pipelines in San Diego County that deliver the
majority of the region's water supply, according to the Water Authority.

“This project is an important part of our commitment to ensuring our
regional water system will continue to deliver a safe and reliable water supply
to sustain the region's 3.1 million residents and $186 billion economy,” said
Bill Rose, the agency's director of engineering. “Relining projects are a cost-
effective alternative to completely replacing entire sections of pipeline, and
they have less construction impact to surrounding communities.”

Crews will reline about three miles of pipeline south of state Route 52
in Mission Trails Regional Park, east of Tierrasanta. The work to reinforce the
pipes with steel liners will extend south to Lake Murray Drive and include
relining a half-mile of another pipeline along Lake Shore Drive into La Mesa.

Most of the work will be conducted underground, with 11 access portals
established along the pipeline. Wooden sound walls will be placed at the
portals to lessen noise. Safety barriers around the portals will reduce
available traffic lanes, but streets will remain open, authority officials

The SDCWA previously relined about 30 miles of Pre-Stressed Concrete
Cylinder Pipe installed from the early 1960s to the late 1980s.
