The plant provides secondary treatment, a standard level for small to medium agglomerations in Mexico. It has a designed capacity of 864.00 m³/day and a current discharge volume of 345.60 m³/day, indicating operational capacity below design. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required for discharge into national waters, ensuring compliance with basic pollutant removal standards. The plant's treated effluent likely discharges into local water bodies that drain toward the Gulf of Mexico, given the region's coastal proximity. The facility plays a role in protecting downstream ecosystems, including rivers and coastal zones, from untreated wastewater impacts. Its operation supports the environmental health of the surrounding watershed.

The plant is located inland in Veracruz, within a watershed that drains toward the Gulf of Mexico. The region's hydrology includes rivers such as the Cazones and Tecolutla, which flow into the Gulf. The plant's secondary treatment helps reduce organic load and suspended solids, protecting downstream aquatic habitats and coastal ecosystems from eutrophication and contamination.
