Lagoon Facultative Wastewater Treatment Plant, Unorganized Division No. 21, Manitoba

Lagoon Facultative is a wastewater treatment plant located in Unorganized Division No. 21, Manitoba, Canada. It serves a small population of 626 residents and operates under secondary treatment, which is typical for small communities in the region. The plant is situated near the coast of Hudson Bay, within 10 km of the shoreline. The plant provides secondary treatment, a standard level for Canadian wastewater facilities in rural areas. The plant's discharge volume of 281.20 megaliters per year aligns with the scale of the population served. Canadian regulations under the Wastewater Systems Effluent Regulations (WSER) set national standards for effluent quality, requiring secondary treatment or equivalent for most systems. The treated effluent is discharged into the local watershed, which ultimately drains into Hudson Bay. This coastal environment supports diverse aquatic life, including fish and migratory birds. The plant's proximity to the coast necessitates careful management to protect the sensitive marine ecosystem from nutrient loading and other pollutants.

The plant discharges into the local watershed that flows into Hudson Bay, a large inland sea in northern Canada. This coastal environment is ecologically sensitive, supporting diverse marine life such as beluga whales, seals, and numerous fish species. The area is also an important migratory corridor for birds. Nutrient inputs from wastewater can affect water quality and ecosystem health, making treatment performance critical.
