Marmora Waste Water Treatment Facility - Secondary Treatment in Marmora and Lake, Ontario

The Marmora Waste Water Treatment Facility is a municipal wastewater treatment plant located in Marmora and Lake, Ontario, Canada. It serves a small community of approximately 1,002 residents, providing secondary treatment to ensure compliance with provincial environmental standards. As a secondary treatment plant, it employs biological processes to reduce organic matter and suspended solids. The facility treats an average of 450 cubic meters of wastewater per day. Under Ontario's regulatory framework, plants of this scale are typically required to meet effluent quality standards set by the Ontario Ministry of the Environment, Conservation and Parks. The treated effluent is discharged into a local watercourse that eventually flows into the Trent River system, which drains into Lake Ontario. This connection to the Great Lakes basin underscores the plant's role in protecting downstream aquatic ecosystems and drinking water sources.

The plant discharges into a local stream that flows into the Trent River, a major tributary of Lake Ontario. Lake Ontario is part of the St. Lawrence River system and ultimately drains into the Atlantic Ocean. The watershed supports diverse aquatic life, including fish species such as walleye and bass, and provides habitat for migratory birds. Protecting water quality in this region is important for both ecological health and recreational use.
