Overview
ETE Duartina is a wastewater treatment plant serving Cabrália Paulista, São Paulo, Brazil. It handles a population of approximately 10,650 people as part of the region's sanitation infrastructure.
ETE Duartina is a wastewater treatment plant located in Cabrália Paulista, within the state of São Paulo, Brazil. The facility serves a population of around 10,650 residents, placing it in the small-to-medium agglomeration category for Brazilian sanitation systems. It operates under Brazil's national environmental regulations, which require adequate treatment for municipal wastewater to protect water resources. Brazilian wastewater treatment plants are regulated by federal laws such as the National Environmental Policy and the Water Resources Law, with oversight from state environmental agencies. For plants serving populations of this scale, secondary treatment is typically expected to reduce organic load and suspended solids. The plant's location in the interior of São Paulo state places it within a region where agricultural and urban runoff can influence water quality. The treated effluent from ETE Duartina likely discharges into a local watercourse that flows into the Tietê River basin, a major river system in São Paulo state. The Tietê River ultimately drains into the Paraná River, which is part of the larger Río de la Plata Basin. This downstream connectivity underscores the plant's role in protecting both local streams and the broader aquatic ecosystem.
Environmental context
The plant's receiving water body is likely a tributary of the Tietê River, which flows through the interior of São Paulo state. The Tietê River is a vital waterway for the region, supporting agriculture, industry, and biodiversity. Downstream, the river joins the Paraná River, which feeds into the Río de la Plata estuary. The watershed is ecologically sensitive, hosting diverse aquatic species and serving as a migratory corridor for fish. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this interconnected system.
