Pascual Orozco Wastewater Treatment Plant - San Isidro Pascual Orozco, Chihuahua, Mexico

Pascual Orozco is a wastewater treatment plant located in San Isidro Pascual Orozco, within the municipality of Guerrero, Chihuahua, Mexico. The facility serves a small population of 1,554 residents, providing secondary treatment to manage municipal wastewater. The plant has a designed capacity of 259.20 cubic meters per day and currently discharges approximately 198.72 cubic meters per day. As a secondary treatment facility, Pascual Orozco meets the standard level of treatment required for small agglomerations under Mexican environmental regulations (NOM-001-SEMARNAT-1996), which sets discharge limits for conventional pollutants. The plant operates within the regulatory framework of Mexico's Federal Law for the Prevention and Control of Environmental Pollution, overseen by the National Water Commission (CONAGUA). The plant is situated inland, more than 10 km from the coast, and its treated effluent likely drains into local waterways that eventually feed into the Rio Conchos basin, a tributary of the Rio Grande (Rio Bravo). This watershed supports agricultural activities and provides habitat for native fish species, making proper treatment essential for downstream water quality and ecosystem health.

The plant discharges into local streams that are part of the Rio Conchos watershed, which flows into the Rio Grande (Rio Bravo) and ultimately reaches the Gulf of Mexico. This region in Chihuahua experiences a semi-arid climate, so water resources are critical for both human use and ecological balance. The receiving waters support diverse aquatic life, including native fish species, and are important for irrigation in the surrounding agricultural areas.
