St Theresa 1999 Sequencing Batch Reactor - Manitoba Wastewater Treatment Plant

St Theresa 1999 Sequencing Batch Reactor is a wastewater treatment facility located in Unorganized Division No. 22, Manitoba, Canada. The plant serves a small population of 1,597 residents and operates as a secondary treatment facility, which is appropriate for its scale. The plant uses a sequencing batch reactor process, a type of activated sludge treatment that provides biological nutrient removal. With a discharge volume of 717 cubic meters per day, the facility meets Canadian federal and provincial wastewater regulations, which require secondary treatment for communities of this size. The plant is situated within 10 kilometers of the coast, indicating its discharge likely reaches Hudson Bay via local waterways. The surrounding watershed supports diverse aquatic life and is part of the larger Nelson River drainage basin, which flows into Hudson Bay. The plant's operation helps protect downstream ecosystems from untreated sewage.

The plant discharges treated wastewater into local waterways that drain into Hudson Bay, a large inland sea connected to the Arctic Ocean. The region's watershed supports fish species such as lake trout and walleye, and provides habitat for migratory birds. The plant's secondary treatment reduces organic pollutants and nutrients, helping to maintain water quality in this ecologically sensitive northern environment.
