Greenwood STP is a municipal wastewater treatment facility located in Greenwood, Caddo Parish, Louisiana. The plant serves a small community of about 2,092 residents, providing essential sanitation services for the area. As an inland facility, it operates away from coastal influences, treating wastewater generated from residential sources. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,703.43 cubic meters per day and a current discharge volume of 946.35 cubic meters per day, the facility operates well within its capacity. Under the U.S. Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality, ensuring effluent quality meets state and federal standards. The treated wastewater from Greenwood STP is discharged into local streams that flow into the Red River, a major tributary of the Mississippi River. The Red River basin supports diverse aquatic life and provides water for agriculture and recreation downstream. The plant's advanced treatment helps protect water quality in this ecologically important watershed, reducing nutrient loading and safeguarding downstream habitats.

Greenwood STP discharges into local waterways that drain into the Red River, which flows south to join the Mississippi River and ultimately the Gulf of Mexico. The Red River basin supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. The plant's advanced treatment helps minimize nutrient pollution, which is critical for preventing algal blooms and maintaining oxygen levels in downstream waters.
