With a population served of 183, it is a small-scale facility designed to handle local domestic wastewater. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater. Its designed capacity is 34.56 m³/day, and it currently discharges 17.28 m³/day, indicating it operates below capacity. The treated effluent is discharged into the local environment, likely into a nearby watercourse that drains into the Pacific Ocean via the Gulf of California. The region's agricultural and coastal ecosystems depend on proper wastewater management to prevent nutrient pollution and protect water quality.

The plant is located within 50 km of the coast, in the state of Sinaloa, which borders the Gulf of California. The receiving water body is likely a small stream or arroyo that flows into the Pacific Ocean. The Gulf of California is a biodiverse marine ecosystem supporting fisheries and migratory species. Proper treatment helps reduce nutrient loading and protects coastal water quality.
