Biodisques is a municipal wastewater treatment plant located at 5663 Chemin Lemelin in Ascot Corner, Quebec, Canada. The facility serves a small population of 492 residents in the Le Haut-Saint-François region, operating under Canada's federal and provincial wastewater regulations. The plant provides secondary treatment, which is the standard level required by Canadian regulations for communities of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring the effluent meets quality standards before discharge. The plant's daily discharge volume is 221.00 cubic meters. The treated effluent from Biodisques is released into the local watershed, which ultimately drains into the Saint-François River and then into the St. Lawrence River. This water body supports diverse aquatic life and is an important part of the regional ecosystem. The plant plays a key role in protecting downstream water quality in the St. Lawrence River basin.
Environmental context
The plant discharges into the Saint-François River watershed, which flows into the St. Lawrence River, one of Canada's most significant waterways. The St. Lawrence River supports a wide range of aquatic species and provides drinking water for millions. The secondary treatment process helps reduce nutrient and organic pollutant loads, protecting the river's ecological health and preventing eutrophication in downstream estuaries.
