Cofradía de Morelos Wastewater Treatment Plant, Colima, Mexico

Cofradía de Morelos is a wastewater treatment plant located in the town of Cofradía de Morelos, within the municipality of Tecomán, Colima, Mexico. The plant serves a population of approximately 2,921 residents, making it a small-scale facility in a rural coastal setting. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 259.20 m³/day and an actual discharge volume of 276.48 m³/day, the plant operates slightly above its design capacity, indicating potential stress on the system. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean. The plant's proximity to the coast (within 10 km) means that its discharge can directly affect coastal water quality and marine ecosystems in the region.

The plant discharges into the Pacific coastal watershed of Colima, a region characterized by tropical dry forests and important coastal lagoons. The receiving waters support diverse aquatic life and are part of a migratory corridor for marine species. The plant's coastal location means that any nutrient or pathogen load from its discharge can impact nearshore water quality, affecting both ecological health and local communities that rely on fishing and tourism.
