ETE SUD MENNUCCI - Secondary Wastewater Treatment Plant in Sud Mennucci, São Paulo

ETE SUD MENNUCCI is a municipal wastewater treatment plant located in Sud Mennucci, a municipality in the state of São Paulo, Brazil. The plant serves a population of approximately 6,564 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 under Brazilian regulations for communities of this size. Brazilian environmental legislation, through CONAMA resolutions and state-level permits, mandates secondary treatment to reduce organic load and suspended solids before discharge. The plant's discharge volume is 736.19 m³ per day, reflecting the scale of the community it serves. The treated effluent is discharged into local water bodies that eventually drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water downstream. Proper treatment at ETE SUD MENNUCCI helps protect water quality in this ecologically significant watershed.

The plant discharges into local streams that flow into the Tietê River, a major tributary of the Paraná River basin. The Paraná River system supports extensive biodiversity, including migratory fish species and riparian forests. The region's tropical climate and agricultural land use make nutrient management critical to prevent eutrophication in downstream reservoirs and wetlands.
