Jala Wastewater Treatment Plant, Colima, Mexico

The Jala wastewater treatment plant is located in the municipality of Jala, within the state of Colima, Mexico. It serves a small population of around 1,027 residents, reflecting its role as a local facility for a rural community. The plant operates under Mexico's national water regulations, which require secondary treatment for municipal wastewater to protect public health and the environment. The plant employs secondary treatment processes, which typically involve biological treatment to remove organic matter and suspended solids. With a designed capacity of 864.00 cubic meters per day and an actual discharge volume of 112.32 cubic meters per day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The plant's treatment level aligns with standards set by Mexico's National Water Commission (CONAGUA) for small to medium agglomerations. The treated effluent is discharged into local water bodies within the Colima region, which ultimately drain into the Pacific Ocean via the Armería River basin. This watershed supports diverse aquatic life and agricultural activities downstream. Proper wastewater treatment at Jala helps reduce nutrient and pathogen loads, contributing to the ecological health of the coastal environment and protecting water quality for communities and ecosystems downstream.

The Jala plant discharges into the Armería River basin, which flows through Colima state and empties into the Pacific Ocean near the town of Armería. This coastal watershed supports mangrove ecosystems and estuarine habitats that are important for fish and bird species. The region's tropical climate and agricultural land use mean that nutrient management from wastewater is critical to prevent eutrophication in downstream coastal waters.
