City of Calgary moves closer to restoring Bearspaw feeder main to service.

The city will activate the final pump Friday to return flow to the Bearspaw feeder main; if the system stays stable for 24 hours, officials plan to begin lifting water restrictions.

The City of Calgary says it is approaching a return to full service for the Bearspaw feeder main after emergency repairs. The final pump that supplies water to the feeder main is scheduled to be activated Friday morning. City officials said the system must remain stable for 24 hours after that before the process of removing water restrictions can begin. The feeder main ruptured 17 days ago and normally supplies about 60 per cent of Calgary's drinking water. Key details: - The final pump activation is set for Friday morning as part of a phased return to service. - City officials stated a 24-hour stability period after activation is required before restrictions are expected to be lifted. - Since the feeder main was shut down, the Glenmore Reservoir has been supplying roughly three times its normal volume. - On Wednesday, water use in Calgary was reported at 501 million litres, above the city's stated sustainable target of 485 million litres for the reservoir. - The city has said residents near the break may see an increased presence of work crews, firefighters, police, peace officers and utility staff as crews prepare for the pipe's return to service. Summary: If the system remains stable for 24 hours after the final pump is activated, the city intends to begin removing water restrictions. Officials continue to describe the return to service as a careful, phased process, and local presence around the repair site is expected while crews monitor the pipe.
