Ignacio Zaragoza Wastewater Treatment Plant, Pánuco de Coronado, Durango, Mexico

Ignacio Zaragoza is a wastewater treatment plant located in Pánuco de Coronado, Durango, Mexico. It serves a small community of 790 people, providing secondary treatment to municipal wastewater. The plant is situated inland, more than 10 km from the coast, and operates within the regulatory framework of Mexico's national water laws. The plant has a designed capacity of 103.68 cubic meters per day and currently discharges 86.40 cubic meters per day of treated wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting Mexican standards for discharge into inland waters. The plant's operations are subject to oversight by Mexico's National Water Commission (CONAGUA), which issues permits and ensures compliance with environmental regulations. The treated effluent from Ignacio Zaragoza is discharged into local water bodies that eventually drain into the Pacific Ocean via the Nazas River basin. The surrounding region is semi-arid, and the plant plays a crucial role in protecting local water quality and supporting downstream ecosystems, including agricultural areas and wildlife habitats.

The plant discharges into the Nazas River basin, which flows through Durango and eventually reaches the Pacific Ocean via the Laguna de Mayran and the Rio Grande de Santiago. The semi-arid climate makes water resources scarce, and the plant's secondary treatment helps maintain water quality for downstream agricultural and ecological uses. The region supports diverse aquatic life and migratory birds, making effective wastewater treatment essential for environmental health.
