HOMER STP - Secondary Wastewater Treatment Plant in Homer Township, Michigan

HOMER STP is a municipal wastewater treatment plant located in Homer Township, Calhoun County, Michigan. The facility serves a population of approximately 2,341 residents, providing secondary treatment to meet state and federal water quality standards. As a small-scale plant, it plays a key role in managing local wastewater in this rural community. The plant operates with a designed capacity of about 1,098 million gallons per day and currently treats an average daily flow of 644 million gallons, indicating moderate utilization. Under the U.S. Clean Water Act, secondary treatment is the minimum required for municipal plants, ensuring removal of biodegradable organics and suspended solids. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The treated effluent from HOMER STP discharges into nearby streams that drain into the Kalamazoo River basin, ultimately reaching Lake Michigan. The plant's operations help protect local water quality and aquatic habitats in the Great Lakes ecosystem. Its inland location reduces direct marine impact, but careful management is essential to prevent nutrient loading in the sensitive Great Lakes watershed.

HOMER STP discharges into tributaries of the Kalamazoo River, which flows westward through Michigan and empties into Lake Michigan at Saugatuck. The Kalamazoo River watershed supports diverse aquatic life, including fish species such as steelhead and smallmouth bass. The plant's secondary treatment helps reduce organic pollutants and nutrients that could otherwise contribute to eutrophication in Lake Michigan, a vital freshwater resource.
