MIDDLETOWN WWTP - Secondary Treatment Plant in Middletown, Missouri

MIDDLETOWN WWTP is a municipal wastewater treatment facility located on Post Oak School Road in Middletown, Montgomery County, Missouri. The plant serves a small population of 167 residents, reflecting the rural character of the area. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants. With a designed capacity of 121.13 units and a current discharge volume of 75.71 units, the plant operates below its maximum capacity, indicating headroom for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Mississippi River basin. As part of the Missouri watershed, the plant plays a role in protecting downstream water quality in the Mississippi River system, which supports diverse aquatic life and provides drinking water for millions.

The plant discharges into a tributary of the Mississippi River basin, which flows through the central United States to the Gulf of Mexico. The Mississippi River supports a wide range of aquatic species and is a critical migratory corridor for birds and fish. Downstream, the river contributes to the Gulf's hypoxic zone, making nutrient management important for regional water quality.
