San Luis Temalacayuca Wastewater Treatment Plant, Puebla, Mexico

San Luis Temalacayuca is a wastewater treatment plant located in the municipality of Tepanco de López, Puebla, Mexico. It serves a small population of 2,464 residents, reflecting its role in managing domestic wastewater for this rural community. The plant operates at a designed capacity of 233.28 units, with a corresponding discharge volume, indicating consistent operation within its infrastructure limits. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is typically required for discharges into national waters, ensuring compliance with environmental standards for small agglomerations. The treated effluent is discharged into local water bodies that ultimately drain into the Papaloapan River basin, which flows into the Gulf of Mexico. This region supports diverse aquatic ecosystems and agricultural activities, making proper wastewater management critical for protecting downstream water quality and community health.

The plant discharges into local streams that are part of the Papaloapan River basin, one of Mexico's major river systems flowing into the Gulf of Mexico. This watershed supports a variety of aquatic life and provides water for irrigation and domestic use. Proper treatment helps prevent nutrient pollution and pathogen contamination in downstream ecosystems, which are important for biodiversity and local livelihoods.
