Glasgow WWTP - Secondary Wastewater Treatment in Howard County, Missouri

Glasgow WWTP is a municipal wastewater treatment facility located in Howard County, Missouri, serving a population of approximately 1,100 residents. The plant provides secondary treatment, a standard level required by the U.S. Clean Water Act for most municipal facilities to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 681.37 thousand gallons per day and currently processes an average daily flow of 529.96 thousand gallons, operating below its design capacity. Under the National Pollutant Discharge Elimination System (NPDES), the plant must comply with effluent limits set by the Missouri Department of Natural Resources. The treated effluent is discharged into local streams that drain into the Missouri River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting water quality in this rural agricultural region, helping to reduce nutrient loading and maintain the ecological health of downstream aquatic habitats.

The plant discharges into tributaries of the Missouri River, which flows into the Mississippi River and then to the Gulf of Mexico. This watershed supports diverse aquatic life and is part of the larger Mississippi River basin, an important migratory corridor for birds and fish. The region's agricultural land use means the plant helps mitigate nutrient pollution that could otherwise contribute to hypoxia in the Gulf.
