The plant's inland location and small population served reduce its environmental footprint, though proper nutrient management remains important for downstream water quality.

Belle WWTP discharges into local waterways that flow into the Gasconade River, which joins the Missouri River and ultimately the Mississippi River. This watershed supports diverse aquatic species, including game fish and freshwater mussels. The plant's inland location and small discharge volume minimize direct marine impact, but nutrient loading from secondary treatment can affect downstream ecosystems, particularly in sensitive areas of the Mississippi River basin.
