Ixtlan de Juarez Wastewater Treatment Plant, Oaxaca, Mexico

The Ixtlan de Juarez wastewater treatment plant is located in the town of Ixtlan de Juarez, Oaxaca, Mexico. It serves a population of approximately 1,982 residents, making it a small-scale municipal facility in the Sierra Norte region. The plant is situated in a mountainous area with a temperate climate. The plant provides secondary treatment, which is the standard biological treatment process for organic matter removal. With a designed capacity of 345.60 cubic meters per day and an average discharge volume of 259.20 cubic meters per day, it operates below its design capacity. Mexican wastewater treatment plants are regulated under NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent is discharged into local water bodies that ultimately drain into the Papaloapan River basin, which flows into the Gulf of Mexico. The surrounding ecosystem includes cloud forests and diverse wildlife, making proper wastewater treatment essential for protecting downstream water quality and aquatic habitats.

The plant discharges into local streams that are part of the Papaloapan River basin, which drains into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for communities downstream. The mountainous terrain and high rainfall in the region make the area ecologically sensitive to pollution, as contaminants can quickly affect downstream ecosystems.
