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 in Bonsall and Fallbrook.
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.
The leaking valve was installed in 1980 and is at the end of its useful service life. While valve failure wasn’t an immediate threat, staff had to find a quick solution to avoid delays that could have impacted water deliveries to customers.
