Lampazos de Naranjo Wastewater Treatment Plant, Nuevo León, Mexico

Lampazos de Naranjo is a wastewater treatment plant located in the city of Lampazos de Naranjo, Nuevo León, Mexico. It serves a population of 2,738 people, typical of a small agglomeration in the region. The plant is situated in an inland area, far from the coast, and its operations are part of the municipal infrastructure managed by local authorities. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. With a designed capacity of 1,296 m³/day and an actual discharge volume of 259.20 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a river or stream within the Rio Grande basin, which ultimately drains into the Gulf of Mexico. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's arid and semi-arid environments.

The plant discharges into a local water body within the Rio Grande (Río Bravo) basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic life and is an important water source for agriculture and communities in the arid region of northern Mexico. The secondary treatment helps reduce nutrient and organic pollution, mitigating impacts on downstream ecosystems.
