Lo de Villa Wastewater Treatment Plant, Colima, Mexico

Lo de Villa is a municipal wastewater treatment plant located in Colima, the capital city of the state of Colima, Mexico. The plant serves a population of about 9,127 residents, making it a small-scale facility within the urban infrastructure of the region. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. With a designed capacity of 864 cubic meters per day and a discharge volume matching that figure, the plant operates at full capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT standards, which set discharge limits for pollutants. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Armería River basin. The region's hydrology supports agricultural activities and diverse ecosystems, making proper treatment essential for protecting downstream water quality and aquatic life.

Lo de Villa discharges into the Armería River basin, which flows through the state of Colima and empties into the Pacific Ocean. This coastal watershed supports a variety of aquatic habitats and is important for local agriculture and fisheries. Proper secondary treatment helps reduce nutrient and organic loads, protecting downstream ecosystems from eutrophication and maintaining water quality for both human and ecological use.
