Overview
Ramos Arizpe wastewater treatment plant serves 91,273 people in Coahuila, Mexico. The facility operates under Mexico's national water regulations for municipal wastewater management.
The Ramos Arizpe wastewater treatment plant is located in the city of Ramos Arizpe, Coahuila, Mexico. It serves a population of approximately 91,273 residents, placing it in the medium-to-large agglomeration category for Mexican wastewater infrastructure. The plant is situated inland, about 50 km from the coast, and its operations are governed by Mexico's federal water laws administered by CONAGUA (Comisión Nacional del Agua). Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), wastewater treatment plants serving populations over 50,000 are required to achieve secondary treatment levels with specific pollutant removal efficiencies. The regulatory framework mandates that facilities of this scale implement biological treatment to meet discharge standards for biochemical oxygen demand (BOD), total suspended solids (TSS), and other parameters. The plant discharges treated effluent into local watercourses that ultimately drain into the Rio Grande basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is an important water resource for agriculture and communities in the region. Proper treatment at this facility helps protect downstream water quality and ecological health in the semi-arid landscape of northern Mexico.
Environmental context
The Ramos Arizpe plant discharges into the Rio Grande basin, which flows through Coahuila and into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for irrigation and municipal use in a semi-arid region. The plant's treatment performance is critical for maintaining water quality in downstream ecosystems, including wetlands and coastal habitats along the Gulf coast.
Frequently asked questions
The plant is located at Calle General Hipólito Charles in Ramos Arizpe, Coahuila, Mexico, serving the local population.
The plant serves approximately 91,273 people, classifying it as a medium-to-large agglomeration under Mexican wastewater regulations.
The treated effluent is discharged into local watercourses that are part of the Rio Grande basin, ultimately flowing into the Gulf of Mexico.
The plant operates under Mexico's NOM-001-SEMARNAT standards, which set discharge limits for BOD, TSS, and other pollutants. CONAGUA oversees compliance for facilities serving over 50,000 people.
Mexican regulations require secondary treatment for agglomerations of this size, typically involving biological processes to reduce organic matter and suspended solids before discharge.
