ETE Ipiranguinha is a municipal wastewater treatment plant located in the Ipiranguinha neighborhood of Ubatuba, São Paulo, Brazil. The plant serves an estimated population of 13,370, placing it in the small to medium agglomeration category. Ubatuba is a coastal city in the Região Metropolitana do Vale do Paraíba e Litoral Norte, known for its beaches and Atlantic Forest surroundings. Under Brazilian regulations, wastewater treatment plants are governed by CONAMA resolutions and state-level environmental agencies. For plants of this scale, secondary treatment is typically required to protect receiving water bodies. The facility is part of the municipal sanitation infrastructure managed by the local water utility. The treated effluent from ETE Ipiranguinha ultimately discharges into the Atlantic Ocean via local watercourses. The region's coastal waters support diverse marine life, including fish, crustaceans, and sea turtles, and are important for tourism and fishing. Proper treatment is essential to prevent nutrient pollution and protect the sensitive coastal ecosystem of the Northern Coast of São Paulo.
Environmental context
The plant's discharge enters the Atlantic Ocean along the northern coast of São Paulo, a region characterized by the Serra do Mar mountain range and extensive Atlantic Forest remnants. The coastal waters are part of a productive marine ecosystem that supports artisanal fisheries and tourism. Nutrient loading from untreated or inadequately treated wastewater could lead to eutrophication and harm coral reefs and seagrass beds in the area.
