Ixtepec Wastewater Treatment Plant, Ciudad Ixtepec, Oaxaca, Mexico

The Ixtepec wastewater treatment plant is located in Ciudad Ixtepec, Oaxaca, Mexico, serving a population of approximately 2,738 residents. The facility provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids from wastewater before discharge. With a designed capacity of 432 m³/day and an average discharge volume of 259.20 m³/day, the plant operates at about 60% capacity. As a small-scale municipal facility in Mexico, it falls under the national water quality regulations administered by CONAGUA (Comisión Nacional del Agua), which sets discharge standards for treated wastewater. The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the Tehuantepec River basin. The region is ecologically significant, supporting diverse aquatic life and providing water for agricultural and domestic use downstream. Proper treatment helps protect these water resources from pollution.

The plant discharges into the Tehuantepec River basin, which flows into the Pacific Ocean via the Gulf of Tehuantepec. This coastal watershed supports important mangrove ecosystems and fisheries. Secondary treatment reduces organic load and suspended solids, helping to maintain water quality in the receiving waters and protect downstream aquatic habitats.
