Tumbiscatio Wastewater Treatment Plant, Tumbiscatío de Ruíz, Michoacán

The Tumbiscatio wastewater treatment plant is located in Tumbiscatío de Ruíz, within the municipality of Tumbiscatío in the state of Michoacán, Mexico. The plant serves a population of approximately 2,734 people, reflecting its role in managing domestic wastewater for this small community. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 864 cubic meters per day and an actual discharge volume of 691.2 cubic meters per day, the plant operates below its maximum capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is required for discharges into national waters, ensuring compliance with federal water quality standards. The treated effluent is discharged into local water bodies that ultimately drain into the Pacific Ocean via the Balsas River basin. This region is ecologically significant, supporting diverse aquatic life and providing water for agricultural and domestic use downstream. Proper treatment helps protect the health of these water systems and the communities that depend on them.

The plant discharges into the Balsas River basin, which flows into the Pacific Ocean. This watershed supports a variety of aquatic species and is important for local agriculture and fisheries. The region's tropical climate and seasonal rainfall patterns influence water availability and treatment needs, making consistent wastewater management critical for maintaining downstream water quality and ecosystem health.
