The facility serves a population of approximately 14,089 residents, placing it in the small to medium agglomeration category for Mexican wastewater infrastructure. As a Mexican wastewater facility, the plant operates under the national regulatory framework established by the Comisión Nacional del Agua (CONAGUA), which sets discharge standards under NOM-001-SEMARNAT. For communities of this scale, secondary treatment is typically required to meet water quality objectives for receiving water bodies. The plant's treated effluent ultimately drains into the local hydrological network within the Lerma-Santiago-Pacifico basin, which flows toward the Pacific Ocean. This watershed supports agricultural activities and provides water for communities downstream, making proper treatment essential for protecting both human health and aquatic ecosystems.

The plant discharges into the Lerma-Santiago-Pacifico basin, which drains through the Santiago River and eventually reaches the Pacific Ocean. This watershed supports diverse aquatic life and is important for regional water supply. Proper treatment helps protect downstream communities and ecosystems from nutrient pollution and pathogens.
