Lexa WWTP - Wastewater Treatment Plant in Lexa, Arkansas

Lexa WWTP is a municipal wastewater treatment facility located in Lexa, a small town in Phillips County, Arkansas, United States. The plant serves a population of 286 and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for municipal wastewater treatment. The plant's designed capacity is 181.70 thousand gallons per day, and it currently discharges an average of 193.06 thousand gallons per day, indicating it is operating near or slightly above its design capacity. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids before discharge. The treated effluent is discharged into a local water body, likely a tributary of the Mississippi River basin, given the location in eastern Arkansas. The plant plays a role in protecting downstream water quality in the Mississippi River system, which ultimately drains into the Gulf of Mexico.

Lexa WWTP discharges into a local waterway that is part of the Mississippi River basin, one of the largest drainage systems in North America. The Mississippi River carries treated effluent and other runoff to the Gulf of Mexico, where nutrient pollution contributes to seasonal hypoxic zones. The plant's secondary treatment helps reduce organic pollutants but may not fully address nutrient removal, which is a concern for downstream ecosystems.
