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.
