Overview
ETE Cruzeiro Sao Bento do Sul is a secondary treatment plant serving 4,046 people in São Bento do Sul, Santa Catarina, Brazil. It discharges 483.84 m³/day of treated wastewater into local waterways.
ETE Cruzeiro Sao Bento do Sul is a municipal wastewater treatment plant located in the Cruzeiro neighborhood of São Bento do Sul, a city in the state of Santa Catarina, Brazil. The plant serves a population of approximately 4,046 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required by Brazilian regulations (CONAMA Resolution 430/2011) for most inland wastewater discharges. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring the effluent meets quality standards before release. The plant treats an average daily flow of 483.84 cubic meters. The treated effluent is discharged into local water bodies that ultimately drain into the Rio Negro basin, a tributary of the Iguaçu River. This river system flows through the Atlantic Forest biome, supporting diverse aquatic life and providing water for downstream communities. Proper treatment at this plant helps protect water quality in the region's sensitive watershed.
Environmental context
The plant discharges into local streams that feed the Rio Negro, part of the Iguaçu River basin. This watershed drains the Atlantic Forest, a biodiversity hotspot with high endemism. The river system supports fish populations and provides water for agriculture and urban use downstream. Effective secondary treatment reduces organic pollution and nutrient loading, helping maintain ecological balance in this sensitive subtropical ecosystem.
