WOOD TWP STP - Advanced Wastewater Treatment in Malartic, Quebec

WOOD TWP STP is an advanced wastewater treatment facility located in Malartic, a small town in the Abitibi-Témiscamingue region of Quebec, Canada. The plant serves a population of approximately 1,223 residents, reflecting its role in managing municipal wastewater for a small community. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant has a designed capacity of 529.96 m³/day and currently discharges 378.54 m³/day of treated wastewater. Under Canadian regulations, wastewater treatment plants are governed by the Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which set national standards for effluent quality. For a plant of this scale, advanced treatment is typical in sensitive watersheds to protect aquatic life. The treated effluent is discharged into local waterways that drain into the Ottawa River watershed, eventually reaching the St. Lawrence River and the Atlantic Ocean. The region's boreal forest and numerous lakes make water quality protection critical for maintaining biodiversity and supporting recreational activities like fishing and boating.

The plant's discharge enters the local watershed, which is part of the Ottawa River basin. This river system flows into the St. Lawrence River, a major waterway that supports diverse aquatic ecosystems, including fish species such as walleye and pike. The surrounding Abitibi-Témiscamingue region is characterized by boreal forests and numerous lakes, making the protection of water quality essential for maintaining ecological balance and supporting local wildlife.
