Ejido Gonzalez Wastewater Treatment Plant, Tamaulipas, Mexico

Ejido Gonzalez is a wastewater treatment plant located in the town of Ejido González, within the municipality of González, Tamaulipas, Mexico. The plant serves a small population of approximately 1,369 residents, reflecting its role in managing domestic wastewater for this rural community. The facility operates with secondary treatment, which is appropriate for its scale and typical for small agglomerations in Mexico. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharges into national waters to meet quality standards. The plant's designed capacity is 140.83 m³/day, and it currently treats 129.60 m³/day, indicating it is operating below its full capacity. The treated effluent is discharged into local water bodies, contributing to the protection of the surrounding environment. The plant is located inland, more than 50 km from the coast, so its discharge does not directly impact marine ecosystems. Instead, it supports the health of local rivers and groundwater, which are vital for agriculture and biodiversity in the region.

The plant discharges into local water bodies within the Soto La Marina River basin, which flows eastward into the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional agriculture. The secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream ecosystems from nutrient enrichment and oxygen depletion.
