Overview
ETE Mesópolis is a secondary wastewater treatment plant serving 1,471 people in Mesópolis, São Paulo, Brazil. It discharges treated effluent near the coast, with a daily volume of 212.92 m³.
ETE Mesópolis is a municipal wastewater treatment plant located in Mesópolis, a small town in the state of São Paulo, Brazil. Serving a population of approximately 1,471 residents, the plant is part of the local sanitation infrastructure managed under Brazilian environmental regulations. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. The plant's discharge volume of 212.92 m³ per day reflects the scale of a small community. Brazilian regulations, such as CONAMA Resolution 430/2011, set effluent quality standards for secondary treatment plants. The treated wastewater is discharged into local water bodies that eventually drain into the Paraná River basin, a major hydrological system in South America. The plant's proximity to the coast (within 10 km) means its discharge can influence downstream aquatic ecosystems, including estuarine and marine environments.
Environmental context
The plant discharges into the Paraná River basin, which flows into the Río de la Plata estuary and ultimately the Atlantic Ocean. The receiving waters support diverse aquatic life and are important for regional biodiversity. The plant's coastal proximity means that nutrients and pollutants from treated effluent could affect sensitive estuarine habitats, requiring careful monitoring to prevent eutrophication.
