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.

The Inglewood Sanitary Trunk will provide additional wastewater capacity needed for projected flow from existing and future development as well as population growth in the area. We are essentially installing larger pipes to make sure we continue to provide Calgarians with a high level of service in the face of a growing population.

This project will use trenchless technology to drill a tunnel for the sanitary trunk through Inglewood to connect the 15th St S.E. siphon, located in north Inglewood, and the Bonnybrook Wastewater Treatment Plant.
