en.Wedoany.com Reported - The City of Calgary, Canada, has launched Phase B construction of the Bearspaw South Feeder Main Replacement Project, which will install a new parallel steel feeder main along 34 Avenue N.W. This phase of construction is expected to be completed in October 2026.

Construction began on May 11, 2026, with cross-connection work at two locations to connect the future replacement pipe to the broader water supply system. These two locations are 83 Street N.W. between 33 Avenue N.W. and 34 Avenue N.W., and 77 Street N.W. between 33 Avenue N.W. and 34 Avenue N.W.

Following the completion of cross-connection work, the City will begin feeder main construction on 34 Avenue N.W. in June 2026, starting between 79 Street and 80 Street N.W., and between 85 Street and 86 Street N.W. The construction will use an open-cut method, excavating within the public road right-of-way to install the new pipe, involving trench digging and restoring the surface to its pre-construction condition. The open-cut method was selected for operational reasons, including it being the fastest option for emergency feeder main replacement.

During construction, residents in the area can expect traffic impacts, detours, noise, dust, temporary parking restrictions, and short-term access changes. Drivers are advised to follow detour signs and drive cautiously on residential streets. The City is committed to providing timely and transparent updates, including advance notice of access, parking, and detour changes.

Phase A microtunneling work is progressing as planned from the Shaganappi Pump Station to 73 Street N.W., west of the Bow River. Microtunneling between the shaft at Sarcee Trail and the shaft near the Mainspan apartments on the west side of the Bow River began on April 27, 2026. Construction of the sixth and final tunnel shaft on 16 Avenue N.W. is scheduled to begin on May 11, 2026. Due to ongoing construction, parking availability at Edworthy Park is significantly reduced, and visitors are advised to plan ahead.

Given the condition of the existing pipe, the City is accelerating the replacement of the feeder main. The project will add a parallel steel feeder main to take over service from the current line, improving the reliability and resilience of Calgary's water supply system. The overall replacement project is expected to be completed in December 2026.
