Inglewood sanitary trunk project

When water runs down a sink, drain or toilet, it becomes wastewater. The current sanitary trunk servicing Inglewood and Ramsay that carries wastewater to treatment plants is nearing capacity.

The Inglewood Sanitary Trunk project will add 4km of sanitary pipe to meet growing wastewater needs. This is critical to maintaining a high level of sanitary service in Inglewood, Ramsay, and surrounding communities.

Phase One of the Inglewood Sanitary Trunk (IST) was completed in November 2020. It connects the Inner City Trunk in North Ingle- wood to the Bonnybrook Wastewater Treatment Plant (BBWWTP).

Phase Two of the project will build a new sanitary trunk to connect two existing trunks on the north and south side of the Bow River. When IST Phase One and Two are complete, it will serve a growing population in Calgary’s north neighbourhoods to 2076.

A microtunnelling method will be used for this work. Microtunneling is very precise and less disruptive to the community and the environment than traditional construction, which requires land to be dug up, removed, and replaced once work is complete.

We will also construct two shafts east of the Elbow River, and set up a construction staging area on the south side of the Bow River (7 Avenue and 9 Street S.E. intersection). A small staging area will also be set up on the north side of the river.

Trees will be removed on the south side of the Bow River (December 2023) and north side (January 2024).

Trees removed for the project continue to play a role in the life of our community.

Some removed trees have been repurposed at the Greenview Area Improvements Project for residents to sit, ponder and enjoy the bustling scene on the North side of the Bow River. The City is committed to strong community connections and thoughtful stewardship of natural resources.

Tree removals happen outside the nesting window so birds and species are not disturbed.

Construction will begin December 2023 with tree removals and site set-up on the south side of Bow River. Most activity will happen between 7:00 am to 7:00 pm. Microtunneling will not occur 24 hours a day unless required due to ground conditions.

Area residents may temporarily experience increased noise and vibration, as well as increased construction traffic and noise. We are working closely with our contractor to mitigate these effects wherever possible.

Pathway and road detours will be provided for all closures. Closures may change as the project progresses

Trees removed for the project will continue to play a role in the life of our community.

Some removed trees will be repurposed as horizontal seating at the Greenview Area Improvements Project for residents to sit, ponder and enjoy the bustling scene on the North side of the Bow River. This demonstrates the City’s commitment to strong community connections and thoughtful stewardship of natural resources.

Removing a tree is a last resort. Some trees must be removed so work can be done safely and efficiently. We have adjusted our work so we can save trees wherever possible. 

We will continue to share information with your community as these timelines are confirmed.
