City crews work to fix water main break on 17 Avenue

On Thursday, April 11 The City conducted a routine video inspection of a sanitary main located at 17 Avenue and 14 A Street S.W. Upon inspection, a large void was discovered, indicating a break in the sanitary main. An emergency work plan was developed to minimize both traffic and water services impacts to citizens, while making the necessary repairs as quickly as possible.

When excavation began Saturday morning it was discovered that the scale of repair needed to be increased substantially as there were three pipes - a 600mm storm main, 100mm water main and a 200mm sanitary main - that required repair.

The cast iron water main, installed in 1910, will have a 7 metre portion replaced with PVC pipe. Both the storm main and sanitary main are old clay tile pipe. The sections exposed are cracked and broken. These sections will be removed and replaced with PVC pipe as well.

Water Services crews are currently repairing all three mains and anticipate completion sometime in the afternoon on Tuesday, April 16 barring any unforeseen circumstances. 17 Ave between 14 Street S.W. and 15 St. S.W. will remain fully closed until that time.

At this time one house, one business and one four-story apartment building are without water.Water Services has provided a water wagon as well as pool passes to impacted residents.

Major delays are expected in the area and motorist are advised to consider alternate routes including:
  • 15 Street to 16 Avenue
  • Northbound Crowchild Trail motorists should use 33 Avenue or Bow Trail 
  • Southbound Crowchild Trail, south of Bow Trail, motorists can use 33 Avenue S.W. 
  • Southbound Crowchild Trail at Kensington Road motorists should use Bow Trail or Memorial Drive. 
We thank commuters and Calgarians for their patience and understanding while these utility repairs are undertaken.
