Unidad Habitacional Andres Togores Wastewater Treatment Plant, Poza Rica, Veracruz

Unidad Habitacional Andres Togores is a municipal wastewater treatment plant located in the Chapultepec neighborhood of Poza Rica, Veracruz, Mexico. The facility serves a small population of 274 residents, reflecting its role in a localized residential area within the larger urban context of Poza Rica de Hidalgo. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 30.24 m³/day and an actual discharge volume of 25.92 m³/day, the plant operates at approximately 86% capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is required for discharges into national waters, and this facility meets that standard. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Cazones River basin. The region's tropical climate and proximity to the coast make proper wastewater treatment essential for protecting downstream aquatic ecosystems and coastal water quality.

The plant discharges into the Cazones River basin, which flows eastward into the Gulf of Mexico near the city of Tuxpan. This coastal watershed supports diverse aquatic life, including mangrove ecosystems and estuarine habitats that are important for fish and bird species. The secondary treatment provided helps reduce organic pollution and nutrient loading, mitigating the risk of eutrophication in the receiving waters.
