LA CENTER STP - Ballard County, Kentucky Wastewater Treatment Plant

LA CENTER STP is a municipal wastewater treatment plant located in Ballard County, Kentucky, United States. The facility serves a small population of 1,163 residents, providing secondary treatment to meet state and federal water quality standards. Its location in the Mississippi River watershed places it within a region where wastewater management is critical to downstream water quality. The plant operates with a secondary treatment process, which is the standard minimum for municipal wastewater treatment under the U.S. Clean Water Act. With a designed capacity of 605.66 units and an average discharge volume of 295.26 units, the plant operates at approximately 49% of its capacity, indicating room for future growth. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Kentucky Division of Water. Treated effluent from LA CENTER STP ultimately drains into the Mississippi River basin, which flows into the Gulf of Mexico. The plant plays a role in protecting local waterways from nutrient pollution and pathogens, supporting aquatic life and recreational uses downstream. Its inland location reduces direct marine impact, but its discharge contributes to the broader Mississippi River watershed health.

The plant discharges into the Mississippi River basin, which drains a vast area of the central United States before reaching the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is a critical migratory corridor for fish and birds. Nutrient loading from wastewater can contribute to hypoxic zones in the Gulf, making effective treatment essential for downstream environmental health.
