Ixmatlahuacan Wastewater Treatment Plant, Veracruz, Mexico

The Ixmatlahuacan wastewater treatment plant is located in the city of Ixmatlahuacan, Veracruz, Mexico. It serves a population of 2,929 people, making it a small-scale municipal facility. The plant is situated inland, more than 10 km from the coast, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological treatment required for municipal wastewater in Mexico. It has a designed capacity of 432.00 m³/day and currently discharges 302.40 m³/day of treated effluent. The facility is part of the local sanitation infrastructure managed by the state water authority. The treated effluent is discharged into a local water body that eventually drains into the Gulf of Mexico. The plant plays a key role in protecting downstream ecosystems, including coastal lagoons and estuaries that support diverse aquatic life and fisheries.

The plant discharges into a local watercourse that flows through the Papaloapan River basin, eventually reaching the Gulf of Mexico. This coastal region supports mangrove forests and estuarine habitats that are critical for fish spawning and migratory birds. Proper wastewater treatment helps reduce nutrient loading and protects these sensitive ecosystems from eutrophication.
