The plant has a designed capacity of 264.98 megaliters per year and currently treats 113.56 megaliters annually, indicating available capacity for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Pecos River basin, a tributary of the Rio Grande. This region is part of the arid Chihuahuan Desert ecosystem, where water resources are scarce and sensitive to pollution. The plant's proper operation is critical for protecting downstream aquatic habitats and supporting the ecological health of the Rio Grande watershed.

The plant discharges into local streams that flow into the Pecos River, a major tributary of the Rio Grande. The Rio Grande eventually reaches the Gulf of Mexico, supporting diverse aquatic life in an arid region. The watershed is ecologically sensitive due to low water flows and high evaporation rates, making pollution control essential for maintaining water quality and habitat integrity.
