Laguna de Patos Wastewater Treatment Plant, Ciudad Juárez, Chihuahua

Laguna de Patos is a wastewater treatment plant located in Ciudad Juárez, Chihuahua, Mexico. It serves a population of approximately 22,818 people, placing it in the medium-agglomeration category for Mexican wastewater infrastructure. The plant is situated in an arid region near the US-Mexico border. As a Mexican treatment facility, Laguna de Patos operates under the framework of the National Water Law (Ley de Aguas Nacionales) and is subject to standards set by the National Water Commission (CONAGUA). For plants serving populations between 10,000 and 100,000, Mexican regulations typically require secondary treatment to reduce organic matter and suspended solids before discharge. The plant's treated effluent likely discharges into the Rio Grande (Río Bravo) basin, which flows southeast to the Gulf of Mexico. This river is a critical water source for both Mexico and the United States, supporting agriculture, urban water supply, and diverse aquatic ecosystems in the Chihuahuan Desert region.

The plant is located in the Rio Grande (Río Bravo) watershed, which drains into the Gulf of Mexico. The river supports a unique riparian ecosystem in the arid Chihuahuan Desert, providing habitat for migratory birds and fish species. Downstream, the river forms part of the border between Mexico and the US, and its water quality is managed through binational agreements.
