Killaloe Wastewater Treatment Plant - Secondary Treatment Facility in Ontario, Canada

The Killaloe Wastewater Treatment Plant is located on Keetch Street in Killaloe, part of the township of Killaloe, Hagarty and Richards in Renfrew County, Eastern Ontario, Canada. The plant serves a population of approximately 613 residents, making it a small-scale municipal facility. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids, meeting the typical standards for small communities in Ontario. The plant operates under Ontario's regulatory framework, which aligns with the Canada-wide standards for wastewater systems, ensuring effluent quality is managed to protect receiving waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Ottawa River basin. The Ottawa River flows into the St. Lawrence River, a major waterway that empties into the Atlantic Ocean. The plant plays a role in protecting downstream aquatic ecosystems, including fish habitats and water quality in the region.

The plant discharges into a local watercourse that is part of the Ottawa River watershed. The Ottawa River flows southeast to join the St. Lawrence River near Montreal, which then drains into the Gulf of St. Lawrence and the Atlantic Ocean. The receiving waters support diverse aquatic life, including fish species such as walleye and smallmouth bass, and are important for recreational activities. The plant's secondary treatment helps reduce nutrient and organic loading, mitigating potential impacts on downstream water quality.
