The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the overall health of the downstream environment.

Wheatley WWTP discharges into tributaries of the St. Francis River, which flows into the Mississippi River. The Mississippi River basin is one of the largest in North America, supporting a wide range of fish and wildlife species. Downstream, the river empties into the Gulf of Mexico, where nutrient pollution from upstream sources contributes to seasonal hypoxic zones. The plant's secondary treatment helps mitigate local nutrient and organic matter loading.
