Agua Salada Wastewater Treatment Plant, Colima, Mexico

The Agua Salada wastewater treatment plant is located in the town of Agua Salada, within the municipality of Minatitlán, Colima, Mexico. It serves a small population of approximately 456 residents, reflecting its role as a local facility for a rural community. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. With a designed capacity of 129.60 volume units and an actual discharge volume of 43.20, the plant operates below its capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and overseen by the National Water Commission (CONAGUA), which sets discharge standards to protect water quality. The treated effluent from the plant is discharged into the local environment, contributing to the protection of nearby water bodies. The plant's location inland, away from the coast, means its discharge affects freshwater systems rather than marine environments. The surrounding region is part of the Pacific watershed, with rivers flowing towards the Pacific Ocean.

The plant discharges into local freshwater systems that drain into the Pacific Ocean via rivers in the Colima region. The area supports diverse aquatic life and is important for maintaining water quality in downstream ecosystems. Protecting these waters helps sustain local biodiversity and agricultural activities that depend on clean water sources.
