Edmondson WWTP - Secondary Wastewater Treatment in Edmondson, Arkansas

Edmondson WWTP is a municipal wastewater treatment facility located in Edmondson, Arkansas, United States. The plant serves a small population of 204 residents in the Crittenden County area, providing essential sanitation services to this rural community. The facility operates with secondary treatment, which is the standard level required under the US Clean Water Act for most municipal plants. With a designed capacity of 238.48 units and a current discharge volume of 56.78 units, the plant operates well below its capacity, indicating room for future growth. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The plant's treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. This region is part of the larger Mississippi River watershed, which supports diverse aquatic ecosystems and provides drinking water for millions downstream. The plant's secondary treatment helps reduce organic pollutants and suspended solids before discharge.

The treated effluent from Edmondson WWTP enters local streams that flow into the Mississippi River, one of the largest river systems in North America. The Mississippi River watershed supports a wide range of aquatic life, including fish, mussels, and migratory birds. Downstream, the river empties into the Gulf of Mexico, where nutrient pollution from upstream sources can contribute to hypoxic zones. The plant's secondary treatment helps mitigate this impact by reducing organic loads.
