MONTICELLO WWTP - Secondary Treatment Plant in Monticello, Missouri

MONTICELLO WWTP is a municipal wastewater treatment facility located in Monticello, Lewis County, Missouri. The plant serves a small population of 98 residents, reflecting the rural character of the area. It operates as part of the local infrastructure managed by the community. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 94.64 m3/day and an actual discharge volume of 37.85 m3/day, the facility operates well below its capacity. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Missouri Department of Natural Resources. The treated effluent is discharged into a local waterway, likely a tributary of the Mississippi River system. The plant's location in the Mississippi River basin means its discharge ultimately contributes to the river's flow, which supports diverse aquatic life and provides water for downstream communities. The secondary treatment process helps protect water quality in this ecologically significant watershed.

The plant discharges into a local stream that flows into the Mississippi River, one of the largest river systems in North America. The Mississippi River basin supports a wide range of aquatic species and provides critical habitat for migratory birds. The secondary treatment ensures that the effluent meets standards to protect the river's water quality, which is essential for both ecological health and human uses such as drinking water and recreation.
