SOPER WWT is a municipal wastewater treatment facility located in Soper, Choctaw County, Oklahoma. The plant serves a small population of 300 residents, providing secondary treatment to meet state and federal water quality standards. Its location along US 70 places it within the rural landscape of southeastern Oklahoma. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal facilities. With a designed capacity of 124.92 and a discharge volume of 113.56, the plant manages wastewater for the local community. As a small-scale facility, it is subject to EPA NPDES permitting through the Oklahoma Department of Environmental Quality, ensuring compliance with effluent limits. The treated effluent from SOPER WWT discharges into nearby creeks that flow into the Kiamichi River, a tributary of the Red River. The Red River ultimately drains into the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting local water quality in the Kiamichi River watershed, which supports diverse aquatic life and recreational uses.

The plant discharges into local streams that feed the Kiamichi River, a major waterway in southeastern Oklahoma. The Kiamichi River flows into the Red River, which then joins the Mississippi River and empties into the Gulf of Mexico. This watershed supports diverse fish populations and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream ecosystems.
