CHILLICOTHE WWTP - Livingston County, Missouri Wastewater Treatment Plant

CHILLICOTHE WWTP is a municipal wastewater treatment facility located in Livingston County, Missouri, along US 65. It serves a population of about 8,968 people, placing it in the small to medium agglomeration category under US regulatory frameworks. As a US facility, the plant operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources. For plants of this scale, secondary treatment is typically required to meet effluent limits for biochemical oxygen demand and total suspended solids. The plant's treated effluent flows into local streams that are part of the Missouri River watershed, ultimately draining into the Mississippi River and the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality in a major continental drainage basin.

The plant discharges into tributaries of the Missouri River, which flows into the Mississippi River and then the Gulf of Mexico. This watershed supports diverse aquatic life and provides habitat for migratory fish species. The region's agricultural land use can contribute nutrient runoff, making effective wastewater treatment important for preventing eutrophication downstream.
