New Franklin WWTP - Secondary Treatment Plant in New Franklin, Missouri

The New Franklin Wastewater Treatment Plant (WWTP) serves the community of New Franklin, Missouri, a small town in Howard County. With a population served of about 1,590, this facility is classified as a small-scale municipal treatment plant. It is located near the Katy Trail, a popular recreational path, and operates within the Missouri River watershed. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 870.64 cubic meters per day and currently treats an average daily flow of 757.08 cubic meters, indicating it operates below its full capacity. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Missouri Department of Natural Resources, which sets limits on effluent quality to protect receiving waters. The treated effluent from New Franklin WWTP discharges into a local stream that eventually flows into the Missouri River, a major tributary of the Mississippi River. The Missouri River supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the river system. Its inland location away from coastal areas minimizes direct marine impacts.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The Missouri River basin supports diverse aquatic species and is an important migratory corridor for fish and birds. Nutrient loading from wastewater can contribute to hypoxic zones in the Gulf, making effective treatment critical for downstream water quality.
