Roscommon Twp WWTF - Houghton Lake, Michigan Wastewater Treatment Plant

Roscommon Twp WWTF is a municipal wastewater treatment facility located in Houghton Lake, Roscommon County, Michigan. It serves a population of approximately 4,199 residents, typical of a small community in the northern Lower Peninsula of Michigan. The plant is situated inland, more than 50 kilometers from the Great Lakes coast. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). For a plant serving around 4,200 people, secondary treatment is the standard requirement, with possible additional nutrient controls depending on the receiving water body. The treated effluent likely discharges into a tributary of the Muskegon River or the Au Sable River system, both of which drain into Lake Michigan and Lake Huron, respectively. These watersheds support diverse aquatic life and are important for regional recreation and fisheries. The plant's location in a forested, rural area means its discharge must protect sensitive coldwater streams and inland lakes.

The plant discharges into a watershed that ultimately drains to the Great Lakes, specifically Lake Michigan or Lake Huron via the Muskegon or Au Sable River systems. These rivers support coldwater fisheries, including trout and salmon, and are ecologically sensitive to nutrient loading and temperature changes. The surrounding area features numerous inland lakes and wetlands that provide habitat for waterfowl and migratory birds.
