The facility serves a population of approximately 2,923 residents, classifying it as a small-scale treatment operation in a coastal community. The plant provides secondary treatment, a standard level for municipal wastewater in Mexico under NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. With a designed capacity of 432 m³/day and a discharge volume matching that figure, the plant operates at full capacity, treating the community's wastewater before release. The treated effluent is discharged into the Pacific Ocean, as the plant lies within 10 km of the coast. This coastal discharge requires careful management to protect marine ecosystems, including nearby beaches and coastal waters that support local fisheries and tourism. The plant plays a key role in preventing untreated sewage from reaching the ocean.

The plant discharges into the Pacific Ocean near Tomatlán, Jalisco, a region characterized by coastal lagoons and mangrove ecosystems that provide critical habitat for migratory birds and marine species. The area's watershed drains from the Sierra Madre Occidental to the coast, and the discharge point influences nearshore water quality. Proper treatment is essential to protect the sensitive coastal environment, which supports local fishing communities and biodiversity.
