Ampliacion Actopan Wastewater Treatment Plant, Actopan, Hidalgo, Mexico

Ampliacion Actopan is a wastewater treatment plant located in Actopan, within the state of Hidalgo, Mexico. The facility serves a population of around 13,691 residents, classifying it as a medium-sized agglomeration under Mexican wastewater management frameworks. The plant is situated inland, away from coastal areas, and its operations are subject to national environmental standards. The plant is designed with a capacity of 1.00 cubic meter per second (or equivalent unit). Mexican regulations for wastewater treatment, such as NOM-001-SEMARNAT-1996, set discharge limits for pollutants based on the receiving water body type. Plants serving populations of this scale are typically expected to provide secondary treatment or equivalent to meet these standards. The treated effluent from Ampliacion Actopan is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Pánuco River system. This watershed supports diverse aquatic life and is important for regional agriculture and water supply. The plant plays a key role in protecting downstream water quality and public health in the Actopan area.

The plant discharges into the Actopan River, a tributary of the Tula River, which flows into the Moctezuma River and ultimately the Pánuco River, reaching the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is used for irrigation and municipal water supply downstream. The region's semi-arid climate makes water quality management critical for maintaining ecological balance and human use.
