Atlanta WWTP - Secondary Wastewater Treatment in Atlanta, Kansas

Atlanta WWTP is a municipal wastewater treatment plant located in Atlanta, Cowley County, Kansas, United States. The facility serves a small population of 195 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal plants to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 208.20 volume units and a current discharge volume of 75.71, the facility operates well below its capacity, indicating room for future growth. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Kansas Department of Health and Environment, ensuring compliance with effluent limits. The treated effluent is discharged into local streams that drain into the Arkansas River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. This connection highlights the plant's role in protecting downstream aquatic ecosystems and maintaining water quality in the broader watershed.

The plant discharges into local waterways that are part of the Arkansas River basin, which flows through Kansas and Oklahoma before joining the Mississippi River. This watershed supports diverse aquatic life and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones.
