Inglewood sanitary trunk project

Ongoing Project Activity - Spring 2019

Construction of Shaft 4 at Crossroads Market started in May and is expected to be completed in June. There will be some traffic impacts.

About this project

When water runs down a sink, drain or toilet, it becomes wastewater. Calgary has a system just for wastewater, moving it by gravity and pumps to one of three wastewater treatment plants.

Calgary’s system is made up of 5,491 km of sanitary pipes. The Inglewood Sanitary Trunk will involve the construction of 4 km of sanitary pipe which will provide additional wastewater capacity needed for projected flow from existing and future development.

Project impacts


There will be temporary detours and access restrictions during this project. If detours or restrictions are needed, every effort will be made to work with residents to maintain access for local traffic. There will be no disruption to garbage collection during construction.


Dust levels will be low. There will be some dust during construction of the microtunnelling shafts and open cut construction. The City will respond to dust through street cleaning/sweeping as needed.
