Houston POTW - Chickasaw County, Mississippi Wastewater Treatment Plant

Houston POTW is a municipal wastewater treatment plant located in Chickasaw County, Mississippi, United States. It serves a population of approximately 4,800 residents, placing it in the small-to-medium agglomeration category. The plant is situated in a rural area of northeastern Mississippi, near the town of Houston. As a U.S. facility, Houston POTW operates under the Clean Water Act, administered by the Mississippi Department of Environmental Quality. The National Pollutant Discharge Elimination System (NPDES) permit program sets effluent limits and monitoring requirements. The plant discharges treated wastewater into local waterways that ultimately drain into the Tombigbee River basin, part of the larger Mobile River system flowing into the Gulf of Mexico. The surrounding region features agricultural land and forested areas, with the plant playing a key role in protecting downstream water quality and aquatic habitats.

The plant's discharge enters tributaries of the Tombigbee River, which flows south to join the Alabama River and form the Mobile River, emptying into Mobile Bay and the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and mussel species. The rural setting means the plant helps prevent nutrient pollution and maintain water quality in a region where agriculture is prevalent.
