ETE Campo Florido Wastewater Treatment Plant, Campinas, São Paulo

ETE Campo Florido is a municipal wastewater treatment plant located in the Campo Florido neighborhood of Campinas, in the state of São Paulo, Brazil. The facility serves a population of 1,803 people, making it a small-scale treatment operation within the broader Campinas metropolitan region. The plant provides primary treatment, which involves physical processes such as sedimentation to remove settleable solids. Under Brazilian regulations (CONAMA resolutions and state-level environmental licensing), small plants like this are typically required to meet basic effluent standards. The plant discharges an average of 248.83 m³/day of treated wastewater. The treated effluent from ETE Campo Florido flows into local watercourses that are part of the Piracicaba River basin, which drains into the Tietê River and ultimately reaches the Paraná River basin. This watershed supports diverse aquatic life and provides water for agricultural and urban uses downstream. Proper treatment is essential to protect water quality in this ecologically and economically important region.

The plant discharges into the Piracicaba River basin, a tributary of the Tietê River, which flows into the Paraná River and eventually to the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems and is a critical water source for the Campinas region. Primary treatment reduces suspended solids but does not remove nutrients, so downstream water bodies may be sensitive to nutrient loading, requiring careful management to prevent eutrophication.
