Ignacio Zaragoza Wastewater Treatment Plant, Tecolutilla, Tabasco, Mexico

Ignacio Zaragoza is a wastewater treatment plant located in Tecolutilla, within the municipality of Comalcalco, Tabasco, Mexico. It serves a small population of 183 people, reflecting its role in a rural or peri-urban setting. The plant is situated near the Gulf of Mexico coast, less than 10 km from the shoreline. The plant provides secondary treatment, a standard level for municipal wastewater in Mexico under the national water quality regulations (NOM-001-SEMARNAT). Its designed capacity is 259.20 m³/day, though current discharge volume is 17.28 m³/day, indicating operation well below capacity. As a small facility, it contributes to local sanitation and environmental protection in the region. The treated effluent likely discharges into local waterways that drain into the Gulf of Mexico, part of the Grijalva-Usumacinta basin system. This coastal area supports diverse aquatic life and is ecologically sensitive due to its mangrove ecosystems and fisheries. Proper treatment helps reduce nutrient and pathogen loads, protecting downstream coastal waters and marine habitats.

The plant is located in the Grijalva-Usumacinta basin, one of Mexico's largest river systems, which drains into the Gulf of Mexico. The receiving waters support mangrove forests, estuaries, and important fisheries. As a coastal facility, its secondary treatment helps mitigate impacts on sensitive marine ecosystems, including seagrass beds and coral reefs in the broader Gulf region.
