Tepames Wastewater Treatment Plant, Colima, Mexico

The Tepames wastewater treatment plant is located in the town of Tepames, within the municipality of Colima, Colima, Mexico. It serves a population of approximately 1,701 people, making it a small-scale municipal facility. The plant is situated inland, more than 10 km from the coast, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological treatment required for municipal wastewater in Mexico. It has a design capacity of 2,246.40 m³/day and currently treats a discharge volume of 302.40 m³/day. This capacity utilization suggests the plant has room for future growth or seasonal variations in flow. The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the Armería River basin. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal areas.

The plant discharges into the Armería River basin, which flows westward to the Pacific Ocean. This watershed supports diverse aquatic life and is important for local agriculture and fisheries. The secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream coastal waters.
