The plant's treated effluent flows into local streams and rivers that are part of the Pánuco River basin, which ultimately drains into the Gulf of Mexico. This watershed supports a variety of aquatic species and provides water for irrigation and domestic use in the region. The Gulf of Mexico is a major marine ecosystem that sustains fisheries and biodiversity, making effective wastewater treatment critical to preventing nutrient pollution and protecting coastal habitats.
