Etang Martinville Wastewater Treatment Plant, Martinville, Quebec

Etang Martinville is a wastewater treatment plant located in the small community of Martinville, Quebec, Canada. It serves a population of approximately 205 residents, reflecting its role as a local facility for this rural area in the Estrie region. The plant is situated along Chemin des Sables and operates under the regulatory framework of Quebec's environmental laws. The plant provides secondary treatment, which is the standard level for small communities in Canada. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 92.00 cubic meters per day indicates its modest scale. Canadian wastewater facilities are regulated under provincial and federal guidelines, including the Canadian Environmental Protection Act and Quebec's Regulation respecting wastewater disposal. The treated effluent from Etang Martinville is discharged into the local watershed, which ultimately drains into the St. Lawrence River system via the region's rivers. The plant plays a key role in protecting the water quality of nearby streams and the broader St. Lawrence ecosystem, which supports diverse aquatic life and is an important migratory corridor for fish and birds.

The plant discharges into the local watershed that feeds into the St. Lawrence River, one of North America's largest and most ecologically significant waterways. The St. Lawrence River supports a rich diversity of fish species, including Atlantic salmon and sturgeon, and provides critical habitat for migratory birds. The region's water quality is influenced by agricultural runoff and rural development, making the plant's secondary treatment essential for reducing nutrient and organic pollution.
