Overview
Bonnybrook Wastewater Treatment Plant serves Calgary, Alberta, treating wastewater for over 800,000 residents. It discharges into the Bow River, part of the South Saskatchewan River Basin.
Bonnybrook Wastewater Treatment Plant is a major municipal facility located in Calgary, Alberta, Canada. It serves a population of approximately 811,000, making it one of the largest treatment plants in the province. The plant is situated along the Bow River Pathway in the Alyth/Bonnybrook district. As a large-scale facility, Bonnybrook operates under Alberta's Environmental Protection and Enhancement Act and the Canadian Water Act. For agglomerations of this size, advanced treatment is typically required to protect sensitive receiving waters. The plant's treatment processes are designed to meet stringent effluent quality standards. The treated wastewater is discharged into the Bow River, which flows through Calgary and eventually joins the Oldman River to form the South Saskatchewan River. This river system is vital for downstream communities, agriculture, and ecosystems. The plant plays a key role in maintaining water quality in this important watershed.
Environmental context
The Bow River originates in the Rocky Mountains and flows east through Calgary, eventually draining into the South Saskatchewan River and ultimately into Hudson Bay via the Nelson River system. The river supports diverse aquatic life, including trout and other cold-water species, and is a critical water source for irrigation and municipal use downstream. Bonnybrook's discharge must meet strict limits to protect this sensitive river ecosystem.
