It is situated in the southeastern region of the country, an area characterized by a mix of urban and agricultural land uses. The plant provides secondary treatment, which is the standard biological treatment process required for municipal wastewater in Brazil under national regulations. For small agglomerations like Quadra, secondary treatment effectively reduces organic pollutants and suspended solids before discharge. The plant treats an average daily flow of 121.34 cubic meters, indicating a modest scale appropriate for the local population. The treated effluent from ETE QUADRA is discharged into local water bodies that ultimately 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 plants like ETE QUADRA helps protect water quality in the region's rivers and reservoirs.
Environmental context
The treated effluent from ETE QUADRA enters local streams that flow into the Sorocaba River, a tributary of the Tietê River, which is part of the broader Paraná River basin. This basin drains into the Río de la Plata estuary. The region's aquatic ecosystems support diverse fish species and are important for migratory birds. Maintaining secondary treatment standards helps prevent nutrient enrichment and oxygen depletion in downstream waters.
