Water main replacements

Our water distribution system relies on 4,650 kilometres of water mains to carry quality drinking water from our water treatment plants to homes and businesses across the city.

To continue to serve you and your family with clean drinking water, we have to replace selected water mains. The repairs usually happen in older communities. Crews replace old corroded cast iron pipe with PVC pipe. These pipes last longer and corrode less.

Below is a list of planned water main replacements for 2018.



Start Date


On 7A Street N.E., from Centre Ave. N.E. to 1 Ave. N.E.

September 24


On Macleod Trail S. and Hull Avenue S.W. (100 metres north of Hull Avenue).

November 10

Windsor Park

On 58 Avenue S.W. from 5 Street S.W. to Macleod Trail S. The work at this location will rely upon a traffic diversion strategy to ensure crew safety and allow Chinook Mall patrons to still access parking to the mall.

Located in the back lane of homes that face Winchester Crescent S.W. and Westminster Drive S.W.

October 15
