Anderson WWTP is a municipal wastewater treatment facility located in Anderson, Madison County, Indiana. The plant serves a population of about 85,425, placing it in the medium-to-large agglomeration category under US regulatory frameworks. As a significant facility in the region, it plays a key role in managing wastewater for the Anderson metropolitan area. Under the US Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the Indiana Department of Environmental Management. These permits set effluent limits for biochemical oxygen demand, total suspended solids, and other parameters to protect water quality. The plant's treatment processes are designed to comply with these federal and state regulations. The plant's treated effluent is discharged into the White River watershed, which flows southwest through Indiana. The White River joins the Wabash River, a major tributary of the Ohio River, which ultimately drains into the Mississippi River and the Gulf of Mexico. The White River supports diverse aquatic life and is used for recreation and drinking water downstream. Proper treatment at Anderson WWTP helps maintain the ecological health of this important waterway.
