ETE CAMPOS DE BOITUVA - Secondary Wastewater Treatment Plant in Boituva, São Paulo

ETE CAMPOS DE BOITUVA is a wastewater treatment plant located in Boituva, within the state of São Paulo, Brazil. It serves a population of 5,570 people, classifying it as a small-scale municipal facility. The plant is situated in the interior of São Paulo state, an area characterized by a mix of urban and agricultural land use. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Brazilian environmental legislation, such as CONAMA 430/2011, sets effluent quality standards for discharge into receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Sorocaba River basin, a tributary of the Tietê River. The Tietê River flows through São Paulo state and ultimately reaches the Paraná River system, which empties into the Río de la Plata estuary. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this densely populated region.

The plant discharges into the Sorocaba River basin, part of the larger Tietê River watershed. The Tietê River is a major waterway in São Paulo state, flowing through the metropolitan region and eventually joining the Paraná River. Downstream, the Paraná River feeds the Río de la Plata estuary, which supports diverse aquatic life and is an important ecological and economic resource. The region's subtropical climate and agricultural activity mean that nutrient loading from wastewater can contribute to eutrophication if not properly managed. Secondary treatment helps mitigate this risk by reducing biochemical oxygen demand and nutrient levels.
