FCPWSD 3 Ming Estates Wastewater Treatment Plant, Krakow, Missouri

FCPWSD 3 Ming Estates is a municipal wastewater treatment plant located in Krakow, Franklin County, Missouri, United States. The facility serves a small population of 170 residents and operates under secondary treatment standards, which is the baseline requirement for most US domestic wastewater plants under the Clean Water Act. The plant has a designed capacity of 102.21 units and a current discharge volume of 64.35 units, indicating it operates below its capacity. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting typical National Pollutant Discharge Elimination System (NPDES) permit limits for biochemical oxygen demand and total suspended solids. The treated effluent from FCPWSD 3 Ming Estates discharges into nearby streams that flow into the Meramec River, a major tributary of the Mississippi River. The Meramec River supports diverse aquatic life and is an important recreational and ecological resource in eastern Missouri. The plant's location inland and small service area reduces its environmental footprint compared to larger coastal facilities.

The plant discharges into local waterways that drain into the Meramec River, which flows approximately 220 miles to join the Mississippi River near St. Louis. The Meramec watershed supports a variety of fish and mussel species, including some of conservation concern. Downstream, the Mississippi River carries the combined flows to the Gulf of Mexico, where nutrient loading from upstream sources contributes to the hypoxic zone. The plant's secondary treatment helps reduce organic pollutants but does not remove nutrients like nitrogen and phosphorus.
