City of Melfort Lagoon Wastewater Treatment Plant, Saskatchewan

City of Melfort Lagoon is a wastewater treatment facility located in Melfort, Saskatchewan, Canada. It serves a small population of 323 residents and is classified as a lagoon system providing secondary treatment. The plant is operational and managed as part of the municipal infrastructure for the community. The plant employs secondary treatment, which is appropriate for its small scale. Under Canadian wastewater regulations, such facilities must meet effluent quality standards set by the federal Wastewater Systems Effluent Regulations (WSER) and provincial guidelines from Saskatchewan. These standards ensure that treated wastewater is safe for discharge into the environment. The treated effluent is discharged into local water bodies within the Saskatchewan River basin, which ultimately drains into Hudson Bay. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region's freshwater resources.

The plant discharges into the Saskatchewan River basin, which flows into Lake Winnipeg and eventually reaches Hudson Bay. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment process helps reduce nutrient loads and organic matter, protecting downstream water quality in this sensitive prairie ecosystem.
