From Fox21News.com (Abbie Burke):
The Stanley Canyon Tunnel, which is the primary delivery system of water from Rampart Reservoir to the Pine Valley and McCullough treatment plants, was not damaged, but the Pine Valley Pipeline, which serves as the Stanley Canyon Tunnel’s backup option, was impacted.
Two creek crossings were destroyed, which compromised structures, and parts of the access road were washed away. As a result, some parts of the pipeline are now exposed and undermined.
“Just recently we went over the (Pine Valley) pipeline, rebuilt major portions of the Pine Valley Pipeline to put that back in service to really use it as a reliable source, a secondary source supply, in the event that something happened to the Stanley Canyon Tunnel,” [Andy Funchess, CSU Field Operations Manager for Water System Operations] said.
The Stanley Canyon Tunnel, which now has no healthy backup pipeline, serves 75-80 percent of the city’s water supply.
“The Stanley Canyon Tunnel, which is the primary source which is under the ground, is in fine shape, fine condition. Our water system is still strong, we just want to put those secondary sources back together so that we have a back up plan,” Funchess said…
“It’s going to be months if not years before we actually get this pipeline in working condition again,” Funchess said. Repairs are expected to cost more than $1 million.
