Sur Wastewater Treatment Plant, Ciudad Juárez, Chihuahua, Mexico

Sur wastewater treatment plant is located in Ciudad Juárez, Chihuahua, Mexico, serving a population of 353,123. The plant has a designed capacity of 1.00, indicating its scale as a major municipal facility in the region. It is situated inland, more than 50 km from the coast, and discharges into local water bodies that eventually drain into the Rio Grande basin. The plant operates under Mexico's federal water regulations, including the National Water Law (Ley de Aguas Nacionales) and standards set by CONAGUA (Comisión Nacional del Agua). For a plant serving over 350,000 people, secondary treatment is typically required, with potential for advanced treatment depending on the receiving water body's sensitivity. Regulatory compliance is expected for such a large agglomeration. The treated effluent from Sur plant likely discharges into the Rio Grande (Río Bravo), which forms the border between Mexico and the United States. This river flows into the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream. The plant plays a critical role in protecting water quality in this transboundary river system.

Sur plant discharges into the Rio Grande (Río Bravo) basin, which flows southeast to the Gulf of Mexico. The Rio Grande is a vital water source for arid regions on both sides of the border, supporting agriculture, wildlife, and urban populations. The river's ecological health is sensitive to nutrient loading and contaminants, making effective wastewater treatment essential for maintaining water quality and preventing eutrophication in downstream reservoirs and coastal areas.
