Chillicothe WWTP - Secondary Treatment Facility in Chillicothe, Texas

Chillicothe WWTP is a municipal wastewater treatment facility located on US Highway 287 East in Chillicothe, Hardeman County, Texas. The plant serves a small population of 800 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 484.53 million gallons per year and an actual discharge volume of 143.85 million gallons per year, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Red River basin, contributing to the watershed that flows into the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting local water quality in the semi-arid Texas Panhandle region.

The plant's discharge enters a tributary of the Red River, which flows through Texas and Oklahoma before joining the Mississippi River and emptying into the Gulf of Mexico. The surrounding watershed supports agricultural activities and provides habitat for aquatic species. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive river system.
