Fraccionamiento Buenavista Wastewater Treatment Plant, Antón Lizardo, Veracruz

Fraccionamiento Buenavista is a secondary wastewater treatment plant located in Antón Lizardo, within the municipality of Alvarado in the state of Veracruz, Mexico. The plant serves a population of 2,738 people and has a designed capacity of 259.20 m³/day, with a reported discharge volume matching that capacity. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets maximum permissible limits for pollutants in wastewater discharges into national waters. Plants of this scale are expected to meet secondary treatment standards to protect receiving water bodies. The plant is situated less than 10 km from the Gulf of Mexico coast, making its discharge potentially influential on coastal water quality. The treated effluent likely drains into nearby coastal lagoons or directly into the Gulf, affecting marine ecosystems. The region's hydrology is characterized by rivers and estuaries that support diverse aquatic life and are important for local fisheries.

The plant discharges into the coastal zone of the Gulf of Mexico near Antón Lizardo, Veracruz. The area is part of the Papaloapan River basin, which drains into the Alvarado Lagoon system, a large estuarine complex that supports mangroves, seagrasses, and diverse fish and bird species. The lagoon ultimately connects to the Gulf of Mexico, making the plant's effluent a factor in coastal water quality and marine ecosystem health.
