The plant serves a small population of 639 people, reflecting its role in a rural or semi-urban community. As part of Mexico's wastewater infrastructure, it contributes to local sanitation and environmental protection. The plant provides secondary treatment, which is the standard biological treatment level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. With a designed capacity of 69.12 m³/day and an actual discharge volume of 60.48 m³/day, the plant operates at approximately 87% capacity. This indicates consistent operation within its design parameters. The treated effluent is discharged into the local environment, likely into a nearby watercourse or drainage system that flows into the Pacific Ocean via the Sinaloa River basin. The plant's operation helps protect downstream water quality and supports the ecological health of the region's coastal and freshwater ecosystems.

The plant discharges into the Sinaloa River basin, which drains into the Pacific Ocean. This coastal watershed supports diverse aquatic life and is important for local fisheries and agriculture. The secondary treatment reduces organic pollutants and suspended solids, mitigating impacts on downstream water quality and the marine environment.
