North Madison Co SD Executive Pk Wastewater Treatment Plant, Madison County, Kentucky

North Madison Co SD Executive Pk is a municipal wastewater treatment plant located on Salter Road in Madison County, Kentucky. It serves a small population of 172 residents, reflecting its role as a local facility for a rural or suburban community. The plant operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required by the Clean Water Act for most municipal facilities to reduce organic matter and suspended solids. Its designed capacity is 1135.62 m³/day, with an average daily discharge of 529.96 m³, indicating it operates well below capacity. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, likely a stream or river within the Kentucky River basin, which ultimately drains to the Ohio River and then the Mississippi River. The plant's location inland, over 50 km from the coast, means its discharge affects freshwater ecosystems rather than marine environments. The surrounding area includes agricultural and forested lands, and the plant helps protect local water quality and aquatic life.

The plant discharges into a receiving water body within the Kentucky River watershed, which flows into the Ohio River and eventually the Mississippi River. This inland location supports diverse freshwater habitats, including fish and macroinvertebrate communities. The plant's secondary treatment reduces nutrient and organic pollutant loads, helping to maintain water quality in downstream rivers and reservoirs.
