Enchanted Valley Hidalgo Co MUD Wastewater Treatment Plant, Doffing, Texas

Enchanted Valley Hidalgo Co MUD is a municipal wastewater treatment facility located in Doffing, Hidalgo County, Texas, United States. The plant serves a population of approximately 6,900 residents in the Enchanted Valley area, operating under the regulatory framework of the US Clean Water Act and state-level permits issued by the Texas Commission on Environmental Quality (TCEQ). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 1,400.60 thousand gallons per day and a current discharge volume of 946.35 thousand gallons per day, the facility operates below its maximum capacity, indicating room for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Rio Grande and the Gulf of Mexico. The plant plays a critical role in protecting downstream ecosystems, including sensitive aquatic habitats in the Lower Rio Grande Valley, a region known for its biodiversity and importance to migratory bird species.

The plant discharges into the Rio Grande basin, which flows into the Gulf of Mexico. The Lower Rio Grande Valley is an ecologically sensitive region supporting diverse aquatic life and serving as a critical migratory corridor for birds. Advanced treatment helps reduce nutrient loading, protecting downstream water quality in the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones.
