Ignacio Ramirez Wastewater Treatment Plant, Durango, Mexico

The Ignacio Ramirez wastewater treatment plant is located in the town of Ignacio Ramirez, within the municipality of Guadalupe Victoria, Durango, Mexico. This facility serves a population of 1,460 residents, reflecting its role as a small-scale municipal treatment plant in a semi-arid region of northern Mexico. The plant provides secondary treatment, a standard level for small communities under Mexican water quality regulations (NOM-001-SEMARNAT). With a designed capacity of 326.59 cubic meters per day and an average discharge volume of 138.24 cubic meters per day, the plant operates below its capacity, indicating potential for future growth or seasonal variability. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies, contributing to the protection of the Nazas River basin, which drains into the Laguna de Mayran and ultimately the endorheic basin of the Bolson de Mapimi. The plant's operation helps safeguard downstream water quality and supports the region's agricultural and ecological water needs.

The plant discharges into the Nazas River basin, a vital water system in the semi-arid Durango region. The Nazas River flows into the Laguna de Mayran, a shallow lake that supports local agriculture and wildlife. Downstream, the basin ends in the Bolson de Mapimi, an endorheic basin with unique desert ecosystems. The plant's secondary treatment reduces organic pollutants, protecting these water bodies from eutrophication and maintaining habitat for aquatic species.
