Marten Falls Lagoon Wastewater Treatment Plant, Marten Falls First Nation, Ontario

Marten Falls Lagoon is a wastewater treatment facility located in the remote community of Marten Falls First Nation in Northwestern Ontario, Canada. The plant serves a small population of 105 residents and operates under secondary treatment standards, which is typical for small, rural communities in the province. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. In Ontario, such facilities are regulated under the Ontario Water Resources Act and the Environmental Protection Act, with permits issued by the Ministry of the Environment, Conservation and Parks. The treated effluent is discharged into the local watershed, which ultimately drains into the Albany River system and then into James Bay, a southern extension of Hudson Bay. This remote boreal forest region supports diverse aquatic life, including fish species such as walleye and northern pike, and is an important area for migratory birds.

The plant discharges into a watershed that flows into the Albany River, one of the longest rivers in Ontario, which empties into James Bay. This remote boreal ecosystem is sensitive to nutrient loading and supports species like brook trout and lake sturgeon. The area is also part of the Hudson Bay Lowlands, a vast wetland complex that plays a critical role in carbon storage and waterfowl habitat.
