LOUISE POTW - Humphreys County, Mississippi Wastewater Treatment Plant

LOUISE POTW is a municipal wastewater treatment plant located in Humphreys County, Mississippi, in the United States. The facility serves a small population of 652 residents, reflecting its role in a rural community. The plant is situated near Canal Road in the Mississippi Delta region. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. Its designed capacity is 162.77 million gallons per day, matching the current discharge volume. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The Mississippi Delta is an ecologically significant region, supporting diverse aquatic life and providing critical habitat for migratory birds. The plant's operations help maintain water quality in this sensitive watershed.

The plant discharges into receiving waters that flow into the Mississippi River, which empties into the Gulf of Mexico. The Mississippi River basin is one of the largest in North America, supporting extensive wetlands and diverse fish populations. The Gulf of Mexico receives nutrient-rich waters that can contribute to hypoxic zones, making effective wastewater treatment crucial for downstream ecosystem health.
