Water pressure dropped for about three hours in parts of Squamish on the weekend as a result of a frozen instrument line that forced a control valve to remain closed, a municipal official said this week.
The malfunction occurred on Sunday (Dec. 8), causing homes and businesses in downtown Squamish, Valleycliffe and other parts of the community to see a loss of water pressure or, in some cases, no pressure at all, District of Squamish (DOS) spokeswoman Christina Moore wrote in an email to The Chief on Tuesday (Dec. 10).
The malfunction occurred as a result of a frozen instrumentation line near Plateau Drive, Moore said. The problem occurred when “a small, frozen instrumentation line that forced a control valve to remain closed, which made the water tank appear to the system as though it was full, therefore not triggering additional water to flow into the tank,” Moore wrote.
Since the problem occurred, DOS operations crews have installed new thermal protection on that part of the system and are monitoring the system for any additional damage, Moore said.
“Operations continues to work on the net effect of the issue to understand where the outages were, the extent of the outages, and which businesses were affected,” she said.
“Sunday’s situation presents an opportunity for us to add new redundancies and efficiencies to this particular piece of infrastructure to prevent such a future occurrence.”
