MANITOU WWT - Manitou, Oklahoma Wastewater Treatment Plant

MANITOU WWT is a municipal wastewater treatment facility located in Manitou, Oklahoma, a small town in Tillman County. The plant serves a population of 278 and operates as part of the region's water infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. With a designed capacity of 132.49 volume units and a discharge volume of 113.56, the facility operates within its capacity. US plants of this scale are typically regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Oklahoma Department of Environmental Quality. The treated effluent is discharged into local receiving waters that ultimately drain into the Red River basin, which flows south to the Gulf of Mexico. This contributes to the ecological health of downstream aquatic habitats and supports regional water quality goals.

The plant discharges into local streams that are part of the Red River watershed, which flows into the Gulf of Mexico. This region supports diverse aquatic life and is important for migratory birds. The secondary treatment process helps reduce nutrient and organic loads, protecting downstream water quality in this agriculturally intensive area.
