Nuevo Francisco de Ibarra Wastewater Treatment Plant, Durango, Mexico

Nuevo Francisco de Ibarra is a wastewater treatment plant located in Nuevo Poblado Francisco de Ibarra, San Juan del Río, Durango, Mexico. It serves a small population of 383 residents, providing secondary treatment to municipal wastewater. The plant operates as part of the local water infrastructure in this semi-arid region of northern Mexico. The plant has a design capacity of 69.12 m³/day and currently treats an average daily flow of 36.29 m³/day. As a secondary treatment facility, it meets the standard requirements for organic matter and suspended solids removal. In Mexico, wastewater treatment plants are regulated under NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Nazas River basin. The region's water resources are critical for agriculture and ecosystem health, making proper treatment essential for protecting downstream water quality and aquatic life.

The plant discharges into the Nazas River basin, which flows through the arid landscapes of Durango and eventually reaches the Pacific Ocean. This watershed supports limited but ecologically important riparian habitats and provides water for irrigation. The semi-arid climate means that maintaining water quality in the receiving water bodies is crucial for both human use and the survival of native species.
