CALGARY – Today, The City of Calgary has reached a milestone making significant progress repairing the original feeder main break near 16 Avenue N.W. and Home Road.

The City concluded the inspection on the remaining 300 metres of pipe and preliminary results indicate no new hotspots have been identified. Work is underway developing an inspection plan for the remainder of the network. More details will be shared as they become available.

“This progress would not be possible without the support of our partners both near and far,” says Capital Priorities and Investment Francois Bouchart. “From sourcing materials across North America to collaborating with leading industry professions, our gratitude goes out to all those stepping up to support Calgary as we recover together.”

San Diego County Water Authority sent Calgary a segment of pipe for its feeder main. Repairing the damaged sections remains our top priority. Initial inspections and site prep work are already underway and construction work on the additional areas identified at risk will start  June 17. Crews will continue working 24 hours a day work but will work to mitigate noise throughout the night for area residents.
