Santo Domingo Azteca Wastewater Treatment Plant, Axapusco, Estado de México

Santo Domingo Azteca is a wastewater treatment plant located in the community of Santo Domingo Aztacameca, within the municipality of Axapusco in Estado de México, Mexico. The plant serves a population of approximately 4,564 residents, making it a small-scale facility focused on local wastewater management. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Mexico under the national water law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996. With a designed capacity of 691.20 m³/day and a discharge volume of 432.00 m³/day, the facility operates at about 62.5% of its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local water bodies that ultimately drain into the Gulf of Mexico via the Pánuco River basin. The plant plays a key role in protecting downstream ecosystems and water quality in this semi-arid region of central Mexico.

The plant discharges into local streams that are part of the Pánuco River basin, which flows northeast to the Gulf of Mexico. This region supports diverse aquatic life and is important for migratory birds. Proper treatment helps prevent nutrient pollution and protects downstream water resources used for agriculture and human consumption.
