Hart WWTP - Nazareth, Texas Wastewater Treatment Plant

Hart WWTP is a municipal wastewater treatment plant located in Nazareth, Castro County, Texas. Serving a population of approximately 1,436, the plant provides secondary treatment to meet state and federal water quality standards. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires NPDES permits for discharges to surface waters. The plant has a designed capacity of 681.37 thousand cubic meters per year and currently handles a discharge volume of 227.13 thousand cubic meters per year. Secondary treatment is the standard level for small communities in the U.S., effectively removing organic matter and suspended solids before discharge. Treated effluent from Hart WWTP is released into the local watershed, which drains into the Brazos River basin. The Brazos River flows through central Texas to the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and recreation. The plant plays a key role in protecting downstream water quality in this semi-arid region.

Hart WWTP discharges into the Brazos River basin, which ultimately flows to the Gulf of Mexico. The receiving waters support a variety of fish and wildlife, including species adapted to the region's seasonal flows. The plant's secondary treatment helps reduce nutrient loading and organic pollution, contributing to the ecological health of the Brazos River and its tributaries.
