ETE Porto Novo is a municipal wastewater treatment plant located in the Porto Novo district of Caraguatatuba, São Paulo, Brazil. The plant serves an estimated population of 38,088 people, placing it in the medium-agglomeration category under Brazilian wastewater management frameworks. It operates within the Região Metropolitana do Vale do Paraíba e Litoral Norte, a coastal metropolitan region in Southeast Brazil. As a plant serving a medium-sized population, ETE Porto Novo is subject to Brazilian federal regulations on wastewater treatment, which generally require secondary treatment for discharges into sensitive water bodies. Brazilian environmental agencies, such as CETESB in São Paulo state, oversee compliance with discharge standards. The plant's treated effluent ultimately drains into the Atlantic Ocean via local watercourses in the Litoral Norte region. This coastal area supports diverse marine ecosystems, including mangroves and estuaries, which are sensitive to nutrient loading and require effective treatment to prevent eutrophication. The plant plays a key role in protecting downstream water quality and public health in the Caraguatatuba area.
Environmental context
The plant discharges into local water bodies that flow into the Atlantic Ocean along the northern coast of São Paulo state. This coastal region features ecologically sensitive environments such as mangroves and estuaries that support diverse aquatic life and serve as important nursery habitats for fish and crustaceans. Proper wastewater treatment is critical to prevent nutrient pollution and protect these downstream ecosystems.
