Calgary water safe to drink after Cochrane sewer main break discharges into the Bow River

The City of Calgary is reassuring residents Sunday that water quality is safe in the city, despite a sewer main break upstream in Cochrane.

On Saturday evening, Alberta’s Emergency Response System was activated after a biohazard incident in Cochrane. A main sewer line within the Town of Cochrane broke around 9:40 p.m. triggering the system.

The break caused an overland sewage spill that flowed into the Bow River at the Highway 22 bridge.  Roads in the area were narrowed to one lane to clean up the spill and pathways in the area were also closed.

The break activated the City of Calgary’s Water Services Response Team to monitor the drinking water quality downstream in Calgary.

“As of Sunday morning, we have seen no change in water quality at the Bearspaw Water Treatment Plant,” the City said in a media release issued Sunday morning.

“Calgary’s water remains safe to drink.”

The City is asking people to stay out of the Bow River for the remainder of Sunday. In the meantime, they were doing extra water sampling on the Bow River.

Last night’s emergency alert ended about two hours after it was issued.

Anyone in the area can follow Cochrane.ca for further updates. According to the province, the quality of Cochrane’s drinking water has not been impacted.
