ETE MACATUBA Wastewater Treatment Plant, Macatuba, São Paulo, Brazil

ETE MACATUBA is a municipal wastewater treatment plant located in Macatuba, within the state of São Paulo, Brazil. The facility serves a population of approximately 16,292 residents, making it a medium-sized treatment plant for the region. Its location in the southeastern interior of Brazil places it within a network of water infrastructure that supports both urban and agricultural areas. As a plant in Brazil, ETE MACATUBA operates under the national regulatory framework established by the National Environment Council (CONAMA) and the Ministry of Cities. For a plant serving around 16,000 people, secondary treatment is typically required to meet effluent standards. Brazilian regulations mandate adequate treatment to protect water quality in receiving bodies. The plant discharges treated wastewater into local watercourses that ultimately drain into the Tietê River basin, a major river system in São Paulo state. The Tietê River flows westward across the state and eventually joins the Paraná River, which empties into the Río de la Plata estuary. This downstream connection highlights the plant's role in protecting aquatic ecosystems and water resources used for agriculture and drinking water.

The plant's treated effluent enters local streams that are part of the Tietê River basin, a vital water system in São Paulo. The Tietê River flows through urban and agricultural areas before joining the Paraná River, which drains into the Río de la Plata estuary. This watershed supports diverse aquatic life and provides water for millions of people. Proper treatment at ETE MACATUBA helps prevent nutrient pollution and pathogen contamination, safeguarding downstream ecosystems and water quality.
