FCPWSD 3 Little Fox Creek Wastewater Treatment Plant, Franklin County, Missouri

FCPWSD 3 Little Fox Creek is a wastewater treatment plant located in Franklin County, Missouri, United States. The facility serves a small population of 400 residents and operates under secondary treatment standards. The plant has a designed capacity of 151.42 cubic meters per day and currently discharges 227.13 cubic meters per day. As a secondary treatment facility, it meets the minimum requirements under the US Clean Water Act for municipal wastewater treatment, which mandates secondary treatment for all publicly owned treatment works. The plant's discharge enters local streams that are part of the Mississippi River basin. The receiving waters support aquatic life and contribute to the overall health of the Mississippi River system, which is a major ecological and economic resource for the region.

The plant discharges into local creeks that flow into the Meramec River, a tributary of the Mississippi River. The Meramec River supports diverse aquatic species and is an important recreational resource. Downstream, the Mississippi River carries treated effluent through a vast watershed that ultimately reaches the Gulf of Mexico, where nutrient loading can contribute to hypoxic zones.
