Overview
ETE ALIANCA is a secondary treatment plant in Cerquilho, São Paulo, Brazil, serving approximately 2,793 people. It discharges 363.73 cubic meters of treated wastewater daily.
ETE ALIANCA is a wastewater treatment plant located in the Jardim Sapucaia neighborhood of Cerquilho, within the Sorocaba metropolitan region of São Paulo, Brazil. The facility serves a population of about 2,793 residents, classifying it as a small-scale municipal treatment operation. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA Resolutions), secondary treatment is typically required for urban wastewater to protect receiving water bodies. The treated effluent is discharged into local waterways that ultimately drain into the Sorocaba River basin, a tributary of the Tietê River. The Tietê River flows through São Paulo state and empties into the Paraná River basin, which is part of the larger Río de la Plata drainage system. The plant plays a role in protecting downstream water quality in this ecologically important region.
Environmental context
The plant discharges into the Sorocaba River watershed, which flows into the Tietê River, a major waterway in São Paulo state. The Tietê River eventually joins the Paraná River, forming part of the La Plata Basin, one of South America's largest river systems. This basin supports diverse aquatic life and provides water for millions of people. The region's subtropical climate and agricultural activities make proper wastewater treatment essential for preventing eutrophication and maintaining water quality in downstream reservoirs and rivers.
