A boil water advisory for the City of Revelstoke will remain in effect over the weekend while the city flushes untreated water from the system.
The advisory was issued Friday at about 8 a.m. when a 16-inch water main disconnected inside the Greeley Water Treatment Plant, flooding the building with about an inch of water.
The main brought treated water from the plant into the distribution system.
It was repaired this morning, but while work was being done, the broken pipe was bypassed, sending untreated, unfiltered water through the system, said the city in a news release.
"This was a real-life test of our emergency response protocols, and while we have identified several opportunities for improvement, I am extremely pleased with staff’s response and the assistance we’ve received from Interior Health," said Mike Thomas, the city's director of engineering.
The system is now being flushed of untreated water, so it can replaced by filtered, chlorinated water.
In the meantime, the boil water advisory will remain in affect until Monday, June 8.
