Quick Solution Keeps Pipeline Repairs On Track

When Water Authority crews began dewatering part of the region’s pipeline system for a 10-day shutdown in mid-November, they discovered a leaking valve that threatened to disrupt the time-sensitive operation. At issue was a six-foot diameter valve in the Second Aqueduct that was designed to isolate a section of pipeline so workers could safely make repairs inside a dry section of the massive pipe. Instead, the valve was seeping water, which made it impossible to start the welding work slated for the relining project in Bonsall and Fallbrook.
