The treated effluent from ETE Castelani likely discharges into a local watercourse within the Piracicaba River basin, which flows into the Tietê River and eventually reaches the Paraná River system. This watershed supports diverse aquatic life and provides water for agriculture and urban use downstream. Proper treatment helps protect water quality in this ecologically and economically important region.
Environmental context
ETE Castelani discharges into a tributary of the Piracicaba River, part of the broader Tietê-Paraná watershed. The Piracicaba River flows into the Tietê River, which eventually joins the Paraná River and drains into the Río de la Plata estuary. This basin supports diverse aquatic ecosystems and is vital for regional water supply, agriculture, and industry. Protecting water quality through effective wastewater treatment is essential to prevent eutrophication and safeguard downstream habitats.
