Villa de La Paz Wastewater Treatment Plant, Ixmiquilpan, Hidalgo, Mexico

Villa de La Paz is a wastewater treatment plant located in Ixmiquilpan, Hidalgo, Mexico. It serves a small community of 1,369 people, providing essential sanitation infrastructure for the region. The plant operates with secondary treatment, which is appropriate for its scale and typical for smaller agglomerations in Mexico. The plant has a designed capacity of 172.80 m³/day and currently discharges 129.60 m³/day of treated wastewater. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is required to meet discharge standards for biochemical oxygen demand and total suspended solids. The plant's capacity utilization suggests it operates below its design load, allowing room for future growth. The treated effluent is discharged into the local watershed, which ultimately drains into the Pánuco River basin and then to the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in this semi-arid region of Hidalgo, where water resources are critical for agriculture and local ecosystems.

The plant discharges into the Pánuco River basin, which flows through central Mexico to the Gulf of Mexico. The region's semi-arid climate makes water quality management crucial for supporting local agriculture and aquatic habitats. Downstream ecosystems benefit from reduced pollutant loads, helping maintain biodiversity in the riverine and coastal environments.
