Station d epuration des eaux usees - Saint-Ulric, Quebec Wastewater Treatment Plant

Station d epuration des eaux usees is a municipal wastewater treatment facility located in Saint-Ulric, Quebec, Canada. The plant serves a small population of 975 residents in the Bas-Saint-Laurent region, providing secondary treatment to meet provincial and federal environmental standards. As a secondary treatment plant, it employs biological processes to reduce organic matter and suspended solids. The plant operates under Quebec's environmental regulations, which align with the Canada-wide wastewater standards. For small communities like Saint-Ulric, secondary treatment is the typical requirement to protect receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the St. Lawrence River estuary. This coastal area supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's proximity to the coast underscores the need for effective treatment to minimize nutrient loading and protect marine ecosystems.

The plant discharges into the St. Lawrence River estuary via local streams, a critical habitat for species like the Atlantic salmon and beluga whale. The estuary supports rich biodiversity and is a key stopover for migratory birds. Effective secondary treatment helps reduce nutrient and pathogen loads, safeguarding this sensitive coastal environment.
