Francisco I Madero Dos Wastewater Treatment Plant - Tamaulipas, Mexico

Francisco I Madero Dos is a municipal wastewater treatment plant located in Francisco I. Madero 2, a locality in the municipality of González, Tamaulipas, Mexico. The plant serves a population of approximately 1,450 residents, reflecting its role in managing domestic wastewater for a small community in the northeastern region of the country. The facility operates at the secondary treatment level, which is the standard required by Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater before discharge into water bodies. With a designed capacity of 157.25 units and an actual discharge volume of 252.29 units, the plant handles flows typical for a small agglomeration. The plant's performance is subject to federal environmental standards that set limits on pollutants such as biochemical oxygen demand and total suspended solids. The treated effluent is discharged into local watercourses that ultimately drain into the Gulf of Mexico via the Pánuco River system or adjacent coastal basins. This discharge contributes to the hydrological balance of the region, which supports agricultural activities and diverse aquatic habitats. The plant's inland location reduces direct marine impact, but its effluent quality is critical for protecting downstream freshwater ecosystems.

The plant's treated wastewater enters local streams that flow toward the Gulf of Mexico, likely through the Pánuco River basin or nearby coastal lagoons. This region supports a mix of agricultural and natural landscapes, with water quality directly affecting downstream fisheries and estuarine habitats. The discharge must comply with Mexican standards to prevent nutrient enrichment and protect aquatic life in receiving waters.
