ETE IPANEMINHA Wastewater Treatment Plant, Sorocaba, São Paulo, Brazil

ETE IPANEMINHA is a wastewater treatment plant located in the Residencial Saint Patrick II neighborhood of Sorocaba, in the state of São Paulo, Brazil. The plant serves a small population of 232 residents, reflecting its role in a localized community within the broader Sorocaba metropolitan region. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations for municipal wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges 52.70 cubic meters of treated wastewater daily. The treated effluent is released into local water bodies that ultimately drain into the Sorocaba River basin, part of the larger Tietê River watershed. The Tietê River flows through São Paulo state and eventually reaches the Paraná River basin. The plant's operation helps protect downstream water quality in this densely populated and industrialized region.

The plant discharges into the Sorocaba River basin, which flows into the Tietê River, a major waterway in São Paulo state. The Tietê River is ecologically significant, supporting diverse aquatic life and providing water for millions of people. The region faces challenges from urbanization and industrial activity, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
