PTAR Tepehuacan de Guerrero - Secondary Wastewater Treatment in Tepehuacán de Guerrero, Hidalgo

PTAR Tepehuacan de Guerrero is a municipal wastewater treatment facility located in Tepehuacán de Guerrero, a town in the state of Hidalgo, Mexico. The plant serves a population of 1,825, classifying it as a small-scale treatment facility within the region's water infrastructure. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 172.80 m³/day and a discharge volume matching that figure, the facility operates at full capacity. As a Mexican plant, it falls under the national water quality regulations (NOM-001-SEMARNAT-1996) that set discharge limits for municipal wastewater. The treated effluent is discharged into local surface waters, ultimately draining into the Pánuco River basin and flowing toward the Gulf of Mexico. This small plant plays a vital role in protecting downstream water quality and public health in the Sierra Madre Oriental region.

The plant discharges into the Pánuco River basin, which flows northeast through Hidalgo and Veracruz before emptying into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The secondary treatment helps reduce nutrient and organic loads, mitigating eutrophication risks in the river system and coastal zone.
