The facility's capacity utilization appears to be at 100%, indicating it operates at full design capacity. The treated effluent is discharged into local water bodies within the Nazas River basin, which drains into the Laguna de Mayrán, an endorheic basin in northern Mexico. The plant plays a key role in protecting local water resources and supporting the region's semi-arid environment.

The plant discharges into the Nazas River basin, which flows into the Laguna de Mayrán, a closed basin that supports local agriculture and wildlife in the semi-arid region of Durango. The area is ecologically sensitive due to limited water resources, and the treatment plant helps reduce pollution loads that could affect downstream ecosystems and groundwater recharge.
