Estacion La Cruz Wastewater Treatment Plant, Chihuahua, Mexico

Estacion La Cruz is a wastewater treatment plant located in the town of Estacion La Cruz, within the municipality of La Cruz, Chihuahua, Mexico. The facility serves a population of 1,187 and provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under NOM-001-SEMARNAT-1996 regulations. The plant has a designed capacity of 129.60 m³/day and currently treats 112.32 m³/day, indicating a utilization rate of approximately 86.6%. As a secondary treatment facility, it uses biological processes to reduce organic matter and suspended solids before discharge. The plant's operation is part of Mexico's national water infrastructure managed by CONAGUA (National Water Commission). The treated effluent is discharged into local water bodies within the Rio Conchos basin, which flows into the Rio Grande (Rio Bravo) and ultimately into the Gulf of Mexico. This region is semi-arid, making water quality management critical for downstream agricultural and ecological uses. The plant helps protect local water resources and supports the health of the Rio Conchos watershed.

The plant discharges into the Rio Conchos basin, a tributary of the Rio Grande (Rio Bravo), which flows into the Gulf of Mexico. This watershed supports diverse aquatic life and is an important water source for agriculture in the region. The semi-arid climate means that maintaining water quality is essential for both human use and ecosystem health, particularly for downstream communities and habitats.
