Ignacio Zaragoza Wastewater Treatment Plant, Durango, Mexico

Ignacio Zaragoza is a wastewater treatment plant located in the town of Ignacio Zaragoza, within the municipality of Coneto de Comonfort, Durango, Mexico. The plant serves a small population of 333 residents, reflecting its role in a rural or small community setting. It is part of Mexico's decentralized wastewater infrastructure, which aims to improve sanitation and water quality across the country. The plant provides secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. With a designed capacity of 129.60 m³/day and an actual discharge volume of 118.37 m³/day, the plant operates near its design capacity. Under Mexico's national water regulations (Ley de Aguas Nacionales), treatment plants of this scale are required to meet effluent standards for discharge into water bodies, ensuring environmental protection. The treated effluent is likely discharged into a local stream or arroyo that drains into the broader hydrological system of the Nazas River basin, which flows into the Laguna de Mayran and eventually the Gulf of Mexico. The plant's operation helps protect local water resources and supports the ecological health of the region's semi-arid watershed.

The plant discharges into the Nazas River basin, a critical water source in the semi-arid region of Durango. The Nazas River flows into the Laguna de Mayran, an important wetland that supports diverse aquatic life and migratory birds. Proper treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive area.
