Landa de Matamoros Wastewater Treatment Plant, Querétaro, Mexico

The Landa de Matamoros wastewater treatment plant is located in the town of Landa de Matamoros, in the state of Querétaro, Mexico. It serves a population of 1,725 people, making it a small-scale municipal facility. The plant is situated inland, away from coastal areas, and its operations are part of the local water infrastructure. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 216.00 cubic meters per day and an actual discharge volume of 163.30 cubic meters per day, the facility operates below its capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and must comply with official standards (NOM-001-SEMARNAT) for discharge quality. The treated effluent is discharged into a local water body, likely a river or stream within the Pánuco River basin, which ultimately drains into the Gulf of Mexico. The plant plays a key role in protecting local water quality and downstream ecosystems, including the diverse aquatic life in the region's rivers and estuaries.

The plant discharges into a local watercourse that is part of the Pánuco River basin, one of Mexico's major river systems. The Pánuco River flows eastward into the Gulf of Mexico, supporting a variety of freshwater and estuarine habitats. Downstream areas include ecologically sensitive zones that provide habitat for fish, birds, and other wildlife. Proper treatment helps reduce nutrient and pollutant loads, protecting water quality in the basin and the coastal environment.
