Santa María Aticpac Sur Wastewater Treatment Plant, Santa María Aticpac, Estado de México

Santa María Aticpac Sur is a wastewater treatment plant located in the town of Santa María Aticpac, within the municipality of Axapusco in Estado de México, Mexico. The plant serves a population of approximately 3,651 people, reflecting its role in managing domestic wastewater for this small community. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 432.00 volume units and a current discharge volume of 345.60 volume units, the plant operates below its full capacity. Mexican wastewater treatment plants are regulated under the national water law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT standards, which set discharge limits for pollutants. The treated effluent from the plant is discharged into the local environment, contributing to the protection of water resources in the region. The plant's location inland, away from coastal areas, means its discharge affects local rivers and groundwater, which are part of the broader hydrological system of the Estado de México.

The plant discharges into the local watershed within the Estado de México, which ultimately drains into the Gulf of Mexico via the Pánuco River system. The region supports agricultural activities and local ecosystems that depend on water quality. Proper treatment helps prevent nutrient pollution and protects downstream aquatic habitats.
