Unidad Habitacional Alejandro Mondragon Wastewater Treatment Plant, Poza Rica, Veracruz

Unidad Habitacional Alejandro Mondragon is a wastewater treatment plant located in the city of Poza Rica, within the state of Veracruz, Mexico. The facility serves a small population of 274 residents, reflecting its role as a local community treatment system. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 30.24 m³/day and a current discharge volume of 25.92 m³/day, the plant operates within its capacity. Mexican wastewater regulations (NOM-001-SEMARNAT-1996) set discharge standards for pollutants, and secondary treatment typically meets these requirements for small communities. The treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Mexico via the Cazones River or nearby coastal systems. The region's tropical climate and proximity to the coast make proper wastewater treatment essential for protecting downstream aquatic ecosystems and public health.

The plant discharges into the Cazones River basin, which flows eastward into the Gulf of Mexico. This coastal watershed supports diverse aquatic life and is important for local fisheries. The secondary treatment process reduces organic load and pathogens, helping to maintain water quality in the river and downstream marine environment.
