Secondary treatment is typical for small communities, ensuring compliance with basic environmental standards. The treated effluent from El Alferez is discharged into local water bodies, likely contributing to the drainage basin of the Nazas River or the Aguanaval River, both part of the endorheic basin of the Bolsón de Mapimí. This region is characterized by arid and semi-arid conditions, making water resources scarce and sensitive to pollution. The plant's operation helps protect local ecosystems and supports the sustainable use of water in this dry region.
