Long Description:
The treatment of wastewater is a complex process consisting of primary, secondary, and tertiary stages. Calgary has two wastewater treatment facilities: Bonnybrook Wasterwater Treatment Plant and Fish Creek Wastewater Treatment Plant. Together, these treatment plants are capable of treating more than 572 000 cubic metres of wastewater and sewage each day.

The City of Calgary collects all the wastewater that comes out homes, schools, businesses, car washes in a sanitary sewer system. The wastewater flows through the pipe system by gravity or is pumped to the wastewater treatment plants.
