Failure of the force main caused by construction activities: city official

As a precaution, the city has posted swimming warning signs along the waterfront, including the boardwalk, Birch Street, Millenium Park, the boat launch and Sunset Point.

The City of Collingwood said the sanitary force main failure that occurred on July 24 was caused by construction activities near 31 Huron Street.

According to a news release sent by the city Monday evening, staff have now confirmed that the sanitary force main failure at Huron Street and Heritage Drive was caused by construction activities. Discharge lines are pipes that carry waste water under pressure from the discharge side of a pump or pneumatic ejector to a discharge point.

“Drilling at the site caused direct damage to the force main, but the city intends to undertake further inspections of the force main to determine if there is further damage,” noted the city’s public relations officer, Christa Carter, in the statement.

“The developer and the builder responsible for the construction activity cooperated to resolve the issue.”

City staff estimate that approximately 1,500 cubic meters of untreated sewage was released during the July 24 event, but 115 cubic meters were transported to the sewage treatment plant for treatment and another small pump was installed to send the liquids to a nearby sanitary manhole.

“The health and safety of the public is the city’s No. 1 concern,” Carter said, also noting that out of an abundance of caution, the city has posted swimming warning signs along the waterfront, including the boardwalk, Birch Street, Millenium Park, boat launch and Sunset Point.

“The city is working with the Simcoe Muskoka District Health Unit and will be testing water in recreational swimming areas. Signage will be removed and public notification will follow when swimming advisories are lifted,” she said. .
