The facility serves a small population of 944 residents, reflecting its role in managing local domestic wastewater in a rural or peri-urban setting. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 172.80 thousand cubic meters per year and an annual discharge volume of 95.04 thousand cubic meters, the plant operates below its full capacity. In Mexico, wastewater treatment plants of this scale are regulated under the Ley de Aguas Nacionales and Normas Oficiales Mexicanas (NOMs), which set effluent quality standards for discharge into water bodies. The treated effluent is discharged into local waterways that drain toward the Pacific Ocean, contributing to the protection of downstream aquatic ecosystems. The plant's operation helps reduce pollution loads in the region's rivers and supports water quality in the Colima coastal area.

The plant discharges into local streams that flow toward the Pacific coast of Colima. The region's watershed supports diverse aquatic life and is important for local agriculture and fisheries. Proper treatment helps prevent nutrient enrichment and pathogen contamination in downstream water bodies, safeguarding both ecological health and human uses.
