Watermain break causes major flood in southwest Calgary

Calgary fire crews responded to a watermain break in the community of Coach Hill on Tuesday, May 26, 2026.

A substantial watermain break in southwest Calgary created a small lake in a cul-de-sac in the community of Coach Hill on Tuesday night.

Fire crews were called to the area of Coach Hill Road and Coach Gate Way at around 7 p.m. on Tuesday after a watermain broke and started flooding the streets with water.

Water services have shut off the water for the surrounding area. About a metre of water had accumulated in the area.

Officials told CTV News that water services had isolated the leaking valves at about 8:45 p.m. and water levels are receding.

Keith Stall, an on-duty fire chief with the Calgary Fire Department, says fire crews were able to inform residents of the watermain break.

He says two homes in the affected area have flooding to their yards and garages.

Fire crews and water services are on scene using high-volume pumps to bring water levels down.

No injuries were reported. Thirty-one homes in the area are without water for the next 24 hours.
