Blyth STP Wastewater Treatment Plant, North Huron, Ontario

Blyth STP is a municipal wastewater treatment facility located in the community of Blyth, part of the Municipality of North Huron in Huron County, Ontario, Canada. The plant serves a population of approximately 826 people, reflecting a small rural agglomeration. It operates under Ontario's regulatory framework for wastewater treatment, which aligns with the Canada-wide standards for secondary treatment. The plant provides secondary treatment, a standard level for small communities in Ontario, ensuring removal of organic matter and suspended solids. With a reported discharge volume of 371 m³/day, the facility manages the wastewater generated by the local population. As a small plant, it is subject to provincial monitoring and permitting requirements under the Ontario Water Resources Act. The treated effluent is discharged into a local watercourse that ultimately drains into Lake Huron, one of the Great Lakes. Lake Huron supports diverse aquatic life and provides drinking water for millions. The plant's operation is critical for protecting downstream water quality and the ecological health of the Lake Huron basin.

The plant discharges into a tributary of the Maitland River, which flows into Lake Huron at Goderich. Lake Huron is a large freshwater lake with significant ecological value, supporting fish species like lake trout and walleye, and serving as a migratory corridor for birds. The watershed is primarily agricultural, so the plant's nutrient removal helps prevent eutrophication in the lake.
