Boquilla Wastewater Treatment Plant - Boquilla de Babisas, Chihuahua, Mexico

Boquilla wastewater treatment plant is located in Boquilla de Babisas, within the municipality of San Francisco de Conchos, Chihuahua, Mexico. The facility serves a population of 1,599 and operates with secondary treatment, a standard level for small communities under Mexican regulations (NOM-001-SEMARNAT-1996). The plant has a designed capacity of 345.60 m³/day and currently treats 259.20 m³/day of wastewater, indicating operational headroom. As a secondary treatment plant, it reduces organic matter and suspended solids before discharge. Mexican environmental law requires compliance with discharge standards for parameters like BOD, TSS, and pathogens. The treated effluent is discharged into a local water body, likely part of the Rio Conchos basin, which flows into the Rio Grande (Rio Bravo) and eventually to the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in an arid region where water resources are critical for agriculture and ecosystems.

The plant discharges into the Rio Conchos watershed, a tributary of the Rio Grande (Rio Bravo), which flows to the Gulf of Mexico. This arid region relies on limited surface water for irrigation and domestic use. The secondary treatment helps reduce nutrient and pathogen loads, protecting downstream aquatic life and supporting water reuse potential in a water-scarce environment.
