ETE Flores Wastewater Treatment Plant, Rio Claro, São Paulo, Brazil

ETE Flores is a wastewater treatment plant located in Rio Claro, in the state of São Paulo, Brazil. The plant serves a population of approximately 29,981 people, making it a medium-sized facility within the region's sanitation network. Rio Claro is part of the Piracicaba metropolitan region, an area with significant urban and agricultural activity. As a Brazilian wastewater treatment plant, ETE Flores operates under the national regulatory framework established by the National Environmental Council (CONAMA) and the Ministry of Cities. For a plant serving around 30,000 people, secondary treatment is typically required to meet effluent standards before discharge. The plant's design and operation align with Brazil's goals for expanding sanitation coverage and improving water quality in urban areas. The treated effluent from ETE Flores likely discharges into a local watercourse that flows into the Corumbataí River, a tributary of the Piracicaba River. The Piracicaba River basin is an important water source for the region, supporting drinking water supply, agriculture, and industry. Downstream, the waters eventually reach the Tietê River and flow into the Paraná River basin, ultimately draining into the Río de la Plata estuary. Protecting this watershed is critical for maintaining aquatic ecosystems and water quality for multiple uses.

The plant's receiving waters are part of the Corumbataí River basin, which flows into the Piracicaba River. This river system is vital for the region's water supply and supports diverse aquatic life. The Piracicaba River is a tributary of the Tietê River, which eventually joins the Paraná River and drains into the Río de la Plata estuary. The watershed faces pressures from urbanization and agriculture, making effective wastewater treatment essential for preserving downstream water quality and ecological health.
