Conestoga College evacuated its Doon campus in Kitchener and cancelled all classes and activities following a water main break on Old Carriage Drive.

The road was closed between Pioneer Dr and Homer Watson Boulevard. The damage to the water main means the entire Lower Doon area of the city is without water pressure, but Kitchener Utilities anticipates pressure will be restored by around 3 p.m.

About 130 residences near Old Carriage Drive will have water restored by around 8 p.m. as crews work to repair the main, said Kitchener Utilities. 

The closures at Conestoga affect all continuing education and recreation centre activities as well as the campus child care centre. The school is asking parents with children in the care centre to pick them up as soon as possible.

The call to evacuate was made because water pressure was too low for washrooms and fire sprinklers, said Conestoga College Vice President Kevin Mullan.

Although water pressure on campus was restored by 2 p.m., classes will stay cancelled for the day.

Crews from the City of Kitchener and the Region of Waterloo are on scene.

The college says Grand River Transit buses will only be using emergency stops at the entrances to parking lots 8 and 9.
