PTAR Ixtlahuac Wastewater Treatment Plant, Huautla, Hidalgo, Mexico

PTAR Ixtlahuac is a municipal wastewater treatment plant located in the community of Ixtlahuac, within the municipality of Huautla, Hidalgo, Mexico. The plant serves a small population of 456 residents, reflecting its role in a rural or peri-urban setting. It is situated inland, more than 10 km from the coast, but within 50 km of the Gulf of Mexico coastline. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. With a designed capacity of 43.20 volume units and a corresponding discharge volume, the plant operates at full capacity based on available data. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent from PTAR Ixtlahuac ultimately drains into the Panuco River basin, one of Mexico's major hydrological systems, which flows into the Gulf of Mexico. This basin supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment helps protect water quality in this ecologically important region.

PTAR Ixtlahuac discharges into local streams that are part of the Panuco River basin, which drains into the Gulf of Mexico. The Panuco River system supports a variety of freshwater species and provides critical habitat for migratory birds. Downstream waters are used for irrigation and fishing, making effective wastewater treatment essential for maintaining water quality and ecosystem health in this tropical region.
