Julimes Wastewater Treatment Plant, Chihuahua, Mexico

The Julimes wastewater treatment plant is located in the town of Julimes, Chihuahua, Mexico, serving a population of approximately 4,246 residents. The facility provides secondary treatment, a standard level for communities of this size in Mexico, ensuring that organic pollutants are significantly reduced before discharge. With a designed capacity of 656.64 cubic meters per day and an actual discharge volume of 432.00 cubic meters per day, the plant operates below its maximum 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 into national waters. The plant's treated effluent is discharged into local watercourses that eventually drain into the Rio Conchos basin, a major tributary of the Rio Grande (Rio Bravo). This river system supports agricultural irrigation and provides habitat for diverse aquatic species in the arid Chihuahuan Desert region.

The Julimes plant discharges into the Rio Conchos watershed, which flows northward to join the Rio Grande (Rio Bravo) near Presidio, Texas. This river system is critical for water supply in the Chihuahuan Desert, supporting agriculture and wildlife. The treated effluent contributes to base flow in the river, which is essential during dry periods. Downstream, the Rio Grande forms the border between the US and Mexico and eventually empties into the Gulf of Mexico, making nutrient and pollutant control important for both freshwater and marine ecosystems.
