The City of Calgary says the next stage of replacing the Bearspaw South feeder main is set for this month.

Beginning this week, a new parallel steel feeder main will be installed along 34 Avenue, between 73 Street and 89 Street N.W.

Officials say the work will use an open-cut construction method, a process the city says is “the fastest option” to replace the pipe.

It involves excavating within the public right-of-way, the city says.

“This method involves digging a trench and restoring the surface to its pre-construction state,” officials said in a news release.

Crews will begin with cross-connection work to link the new pipe to the existing water system in two locations: at 83 Street N.W. between 33 and 34 Avenue N.W. and 77 Street N.W. between 33 and 34 Avenue N.W.

Next month, the new feeder main will be installed between 79 and 80 Street N.W. and between 85 and 86 Street N.W.

The city says residents in the area are expected to experience delays, detours and other impacts of construction in the area during the entire season.
