Lagoon 1991 Wastewater Treatment Plant, Brocket, Alberta

Lagoon 1991 is a wastewater treatment plant located in Brocket, within the Municipal District of Pincher Creek No. 9, Alberta, Canada. The plant provides secondary treatment for the community's wastewater, ensuring compliance with provincial environmental standards. As a secondary treatment facility, Lagoon 1991 meets the typical requirements for municipal wastewater treatment in Alberta. The province's regulatory framework, under the Environmental Protection and Enhancement Act, mandates appropriate treatment levels to protect water quality. Plants of this scale often operate under permits issued by Alberta Environment and Parks. The treated effluent from Lagoon 1991 is discharged into local water bodies that eventually drain into the Oldman River system, part of the South Saskatchewan River Basin. This basin supports diverse aquatic life and is important for irrigation and recreation in southern Alberta. The plant plays a key role in safeguarding downstream water quality.

The plant discharges into the Oldman River watershed, which flows into the South Saskatchewan River and ultimately into Hudson Bay via the Nelson River system. The region's semi-arid climate makes water quality management critical for sustaining aquatic habitats and agricultural uses. The Oldman River supports species such as rainbow trout and walleye, and the plant's secondary treatment helps reduce nutrient loading.
