ETE GUAICARA Wastewater Treatment Plant, Guaiçara, São Paulo

ETE GUAICARA is a wastewater treatment plant located in Guaiçara, within the state of São Paulo, Brazil. The facility serves a population of about 9,098 people, reflecting its role in managing municipal wastewater for this inland community. As part of Brazil's expanding sanitation infrastructure, the plant contributes to public health and environmental protection in the region. Brazilian wastewater treatment plants typically employ technologies such as activated sludge, stabilization ponds, or anaerobic systems, depending on local requirements. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating its scale relative to the population served. Brazil's regulatory framework, including CONAMA resolutions and state-level environmental agencies, sets standards for effluent quality and treatment performance. The plant discharges treated wastewater into local water bodies that drain into the Tietê River basin, a major hydrological system in São Paulo state. The Tietê River flows through the interior of the state before reaching the Paraná River, which ultimately drains into the Río de la Plata estuary. This downstream connection underscores the plant's role in protecting water quality in a region that supports agriculture, industry, and aquatic ecosystems.

ETE GUAICARA discharges into local streams that are part of the Tietê River basin. The Tietê River flows westward across São Paulo state, joining the Paraná River, which forms part of the La Plata Basin. This watershed supports diverse aquatic life and is important for regional water supply and irrigation. The plant's treatment helps reduce nutrient and pathogen loads, protecting downstream ecosystems and human uses.
