Queseria Wastewater Treatment Plant, Quesería, Colima, Mexico

The Queseria wastewater treatment plant is located in the town of Quesería, within the municipality of Cuauhtémoc, Colima, Mexico. The facility serves a population of approximately 14,193 residents, placing it in the medium agglomeration category for Mexican wastewater infrastructure. As a Mexican wastewater treatment plant, Queseria operates under the national regulatory framework established by the Comisión Nacional del Agua (CONAGUA) and the Ley de Aguas Nacionales. For plants serving populations between 10,000 and 100,000, Mexican regulations typically require secondary treatment to meet discharge standards for organic matter and suspended solids. The plant discharges treated wastewater into the local watershed, which ultimately drains toward the Pacific Ocean via the Armería River basin. This region of Colima features a tropical climate with seasonal rainfall, making proper wastewater treatment important for protecting downstream water quality and aquatic ecosystems.

The Queseria plant discharges into the Armería River basin, which flows through the state of Colima and empties into the Pacific Ocean near the town of Boca de Apiza. This coastal watershed supports diverse aquatic life and is important for local fisheries and agriculture. The tropical climate with distinct wet and dry seasons means that treatment plant performance during heavy rainfall events is critical for preventing untreated overflows into the river system.
