The plant serves a small population of 1,299 residents, reflecting its role in a rural or semi-urban setting. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 777.60 cubic meters per day and currently treats 345.60 cubic meters daily, indicating it operates below its full capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is the standard for municipal wastewater, ensuring compliance with discharge limits for BOD, TSS, and other parameters. The plant's operation is part of Mexico's broader efforts to improve water quality and public health. The treated effluent is discharged into local water bodies, likely tributaries of the Rio Grande de Santiago or the Rio Ameca, which flow into the Pacific Ocean. The region's watershed supports diverse aquatic life and is important for local agriculture and ecosystems. Proper treatment helps protect downstream water quality and reduces environmental impact on the Pacific coastal zone.

The plant discharges into the local watershed, which drains into the Rio Grande de Santiago basin and ultimately reaches the Pacific Ocean. The area supports diverse aquatic habitats and is important for migratory birds and fish species. Effective wastewater treatment is crucial to prevent nutrient loading and protect downstream ecosystems, including coastal lagoons and estuaries.
