LAzaro CArdenas Wastewater Treatment Plant, Lázaro Cárdenas, Chihuahua, Mexico

The LAzaro CArdenas wastewater treatment plant serves the community of Lázaro Cárdenas in the state of Chihuahua, Mexico. This facility is designed to handle the wastewater needs of a small population of 1,159 residents, reflecting its role in a rural or peri-urban setting. The plant is located in the arid northern region of Mexico, where water resources are scarce and treatment is critical for public health and environmental protection. The plant operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharge into water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 345.60 cubic meters per day, and it discharges a similar volume daily, indicating full utilization of its capacity. The facility meets the regulatory expectations for its size and location. The treated effluent is discharged into the local watershed, which ultimately drains into the Rio Bravo (Rio Grande) basin, a major river system that forms part of the border between Mexico and the United States. This river is ecologically significant, supporting diverse aquatic life and providing water for agriculture and communities downstream. The plant's operation helps protect water quality in this important basin, reducing pollution and safeguarding downstream ecosystems.

The plant discharges into the Rio Bravo (Rio Grande) basin, which flows through Chihuahua and into the Gulf of Mexico. This watershed supports a variety of species, including fish and migratory birds, and is a critical water source for arid regions. Proper treatment helps maintain water quality in this ecologically sensitive area, preventing nutrient pollution and protecting downstream habitats.
