Inde Wastewater Treatment Plant, Indé, Durango, Mexico

The Inde wastewater treatment plant is located in the town of Indé, Durango, Mexico, serving a small population of 639 residents. It provides secondary treatment, which is the standard level for municipal wastewater in Mexico under NOM-001-SEMARNAT-1996 regulations. With a designed capacity of 691.20 m³/day and an actual discharge volume of 60.48 m³/day, the plant operates well below its capacity. This suggests the facility is sized for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Nazas River basin. This region is part of the arid to semi-arid climate of northern Mexico, where water resources are scarce and treated wastewater reuse is increasingly important for agriculture and ecosystem maintenance.

The plant discharges into the Nazas River basin, a critical water source in the arid Durango region. The Nazas River flows into the Laguna District, an important agricultural area, and eventually reaches the Mayrán Basin, an endorheic basin. The local watershed supports diverse aquatic life and provides irrigation water, making treated effluent quality essential for downstream ecosystems and human use.
