Hanna Lagoon Wastewater Treatment Plant, Special Area No. 2, Alberta

Hanna Lagoon is a wastewater treatment plant located in Special Area No. 2, Alberta, Canada. It serves a population of approximately 1,597 people, making it a small-scale facility typical of rural communities in the Canadian prairies. The plant is currently operational and plays a key role in managing local wastewater. As a small agglomeration in Canada, the plant operates under provincial regulations administered by Alberta Environment and Parks. Canadian wastewater facilities serving fewer than 5,000 people are typically required to meet secondary treatment standards or equivalent lagoon-based treatment, which is common in rural areas. The plant's treatment process is designed to reduce organic matter and pathogens before discharge. The treated effluent from Hanna Lagoon is discharged into the local watershed, which ultimately drains into the South Saskatchewan River Basin. This basin supports agricultural irrigation, livestock watering, and aquatic habitats. The plant's operation helps protect downstream water quality in this semi-arid region where water resources are critical for both human use and ecosystem health.

Hanna Lagoon discharges into the South Saskatchewan River Basin, a major watershed that flows into the Saskatchewan River and eventually into Lake Winnipeg. The region is semi-arid, and the river system supports irrigated agriculture, livestock, and diverse aquatic life including fish species such as walleye and northern pike. Protecting water quality in this basin is essential for maintaining ecological balance and supporting downstream communities.
