Usine d epuration des eaux usees - Saint-Chrysostome, Quebec Wastewater Treatment Plant

Usine d epuration des eaux usees is a municipal wastewater treatment facility located in Saint-Chrysostome, Quebec, Canada. The plant serves a small community of approximately 1,922 residents and operates under the regulatory framework of Quebec's environmental laws and Canada's Wastewater Systems Effluent Regulations (WSER). As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant's treatment process is classified as secondary, which is the minimum standard required under Canadian federal regulations for most municipal wastewater systems. With a daily discharge volume of 873 cubic meters, the facility is designed to handle the wastewater generated by the local population. The plant is operational and meets the regulatory requirements for small agglomerations in Quebec. The treated effluent is discharged into a local watercourse that eventually flows into the Chateauguay River watershed, which drains into the St. Lawrence River and ultimately the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Chateauguay River and downstream ecosystems, including the St. Lawrence River, which supports diverse aquatic life and is an important migratory corridor for fish.

The plant discharges into a local tributary of the Chateauguay River, which flows into the St. Lawrence River near Montreal. The St. Lawrence River is a major waterway that drains into the Gulf of St. Lawrence and the Atlantic Ocean. The watershed supports diverse aquatic habitats and is important for fish migration, including species such as Atlantic salmon and American eel. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality.
