Agua Fria Barricada Wastewater Treatment Plant, Chihuahua, Mexico

Agua Fria Barricada is a municipal wastewater treatment plant located in the town of Agua Fria, within the municipality of Allende, Chihuahua, Mexico. The plant serves a small population of 148 residents, reflecting its role in a rural or peri-urban setting. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. With a designed capacity of 34.56 m³/day and an actual discharge volume of 25.92 m³/day, the facility operates below its capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent is discharged into local water bodies that ultimately drain into the Rio Conchos basin, a tributary of the Rio Grande (Rio Bravo). This watershed supports agricultural activities and provides habitat for diverse aquatic species. Proper treatment helps protect downstream water quality in this arid region of northern Mexico.

The plant discharges into the Rio Conchos watershed, which flows into the Rio Grande (Rio Bravo) and eventually reaches the Gulf of Mexico. This arid region relies on limited surface water resources, making wastewater treatment critical for maintaining water quality for irrigation and ecosystem health. The downstream environment supports species such as the Rio Grande silvery minnow and various migratory birds.
