New Biological Nutrient Removal (BNR) Basins

The South Wastewater Treatment Plant is the largest Biological Nutrient Removal (BNR) plant south of San Antonio. The BNR WWTP was completed in 2018. The 10 (MGD) million gallons per day operates under a State permit which has been established to control pollutant discharges. The permit is designed to regulate the manner, nature, volume and frequency for discharging from a particular source. The permit establishes specific limits on standards for discharging according to the rules and regulations set by the State of Texas and through our enforcing agency, Texas Commission of Environmental Quality (TCEQ), and according to the federal standards set by Environmental Protection Agency (EPA). This permit also insures that the limits and standards established are met through TCEQ’s annual plant inspections, bio-monitoring, and compliance monitoring. The South BNR WWTP produced over 240 million gallons of Type I reclaimed treated effluent yearly that is utilized at the McAllen Palm View Golf Course and South WWTP for irrigation.
