Overview
New Memphis SD Wastewater is an advanced treatment plant in Clinton County, Illinois, serving 350 people. It treats wastewater to high standards before discharge, supporting local water quality.
New Memphis SD Wastewater is a municipal treatment facility located on Airport Road in Clinton County, Illinois, United States. The plant serves a small population of 350 residents, reflecting its role in a rural or small community setting. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 132.49 volume units and a discharge volume of 105.99, it operates efficiently. As a US plant, it falls under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits, which set strict effluent limits to protect water quality. The treated wastewater is discharged into local waterways that ultimately drain into the Mississippi River basin. This region supports diverse aquatic life and is part of a larger watershed that flows to the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading, which is critical for preventing downstream hypoxia.
Environmental context
The plant discharges into local streams that are part of the Kaskaskia River watershed, a tributary of the Mississippi River. The Mississippi River flows into the Gulf of Mexico, where nutrient pollution contributes to a large hypoxic zone. Advanced treatment at this plant helps mitigate nutrient loads, protecting aquatic ecosystems in the river and the Gulf.
