Abasolo Wastewater Treatment Plant, Abasolo, Nuevo León, Mexico

The Abasolo wastewater treatment plant is located in Abasolo, Nuevo León, Mexico, serving a population of approximately 1,825 residents. The facility provides secondary treatment, which is a standard biological treatment process that removes organic matter and suspended solids. The plant has a designed capacity of 432.00 volume units and currently processes a discharge volume of 172.80 volume units, indicating it operates below its full capacity. Under Mexican regulations, wastewater treatment plants are governed by the National Water Law and NOM-001-SEMARNAT-1996, which sets maximum permissible limits for pollutants in treated wastewater. Secondary treatment is appropriate for communities of this size, ensuring compliance with national standards for discharge into water bodies. The treated effluent from the Abasolo plant is discharged into the local watershed, which ultimately drains into the Gulf of Mexico via the Rio Grande (Río Bravo) basin. The plant plays a crucial role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal environments.

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