Hubbard WWTP - Secondary Treatment Plant in Hubbard, Texas

Hubbard WWTP is a municipal wastewater treatment facility located in Hubbard, Hill County, Texas. The plant serves a population of about 1,400 people, making it a small-scale facility typical of rural communities in the region. Its location along the Hubbard Bypass places it within the local infrastructure network. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 946.35 cubic meters per day and an average discharge volume of 639.74 cubic meters per day, the facility operates well within its capacity. The treatment process meets federal and state regulations under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Texas Commission on Environmental Quality. The treated effluent is discharged into nearby creeks that flow into the Brazos River basin, ultimately reaching the Gulf of Mexico. This discharge supports the ecological health of local streams and contributes to the water balance of the Brazos River watershed, which is vital for agriculture, wildlife, and communities downstream.

The plant discharges into local tributaries of the Brazos River, one of Texas's major river systems. The Brazos River flows southeast through diverse landscapes, including agricultural areas and wetlands, before emptying into the Gulf of Mexico. The river supports a variety of aquatic species and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality and aquatic ecosystems.
