Franklin Wastewater Treatment Plant, Franklin, Texas | Secondary Treatment Facility

The Franklin wastewater treatment plant is located in Franklin, Texas, a small community in Robertson County. The plant serves a population of about 1,300 residents, reflecting its role as a municipal facility for a rural area. It operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 647.30 thousand cubic meters per year and an actual discharge volume of 344.47 thousand cubic meters, the plant operates below its capacity, indicating room for future growth. As a U.S. facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Texas Commission on Environmental Quality, which set effluent limits and monitoring requirements. The treated effluent is discharged into local waterways that drain into the Brazos River basin, a major river system in Texas. The Brazos River flows southeast to the Gulf of Mexico, supporting diverse aquatic life and providing water for agriculture and communities downstream. The plant's secondary treatment helps protect this watershed from nutrient pollution and pathogens.

The plant discharges into local tributaries of the Brazos River, which flows through central Texas to the Gulf of Mexico. The Brazos River basin supports a variety of fish and wildlife, including migratory birds and freshwater species. Secondary treatment reduces organic load and suspended solids, helping maintain water quality in this agriculturally important region.
