San Francisco de Asis Wastewater Treatment Plant, Indé, Durango, Mexico

San Francisco de Asis is a wastewater treatment plant located in Indé, within the state of Durango, Mexico. It serves a small population of 301 people, reflecting its role in a rural or small community setting. The plant is situated inland, far from coastal areas, and operates under Mexico's national water regulations. The plant provides secondary treatment, a standard level for small communities in Mexico. With a designed capacity of 41.47 units and a current discharge volume of 34.56 units, it operates below its capacity, indicating room for future growth or seasonal variations. As a secondary treatment facility, it removes organic matter and suspended solids, meeting basic environmental standards for inland discharge. The treated effluent is likely discharged into a local watercourse that drains into the broader hydrological network of the region. Durango's watersheds ultimately flow towards the Pacific Ocean or inland basins, supporting local ecosystems and agricultural activities. The plant's operation helps protect downstream water quality in this semi-arid region.

The plant discharges into a local watercourse within the Nazas-Aguanaval basin, which drains into the Laguna de Mayrán, an endorheic basin in northern Mexico. This region experiences semi-arid conditions, making water quality crucial for local agriculture and wildlife. The secondary treatment reduces organic pollutants, supporting the ecological health of the downstream environment.
