Overview
ETE TRES FRONTEIRAS is a secondary wastewater treatment plant in Três Fronteiras, São Paulo, Brazil, serving 4,325 people. It discharges 715.18 m³/day of treated effluent and is located within 10 km of the coast.
ETE TRES FRONTEIRAS is a municipal wastewater treatment plant located in Três Fronteiras, a city in the state of São Paulo, Brazil. The plant serves a population of 4,325 and operates with secondary treatment, which is the standard level required for urban wastewater in Brazil under federal regulations. The plant discharges an average of 715.18 m³ of treated effluent per day. Brazil's wastewater treatment regulations, established by CONAMA resolutions and the National Sanitation Plan (PLANSAB), mandate secondary treatment for urban agglomerations to protect water quality. For a plant of this scale, secondary treatment is appropriate to reduce organic load and suspended solids before discharge. The plant's proximity to the coast (within 10 km) means its effluent may eventually reach coastal waters, requiring careful management to avoid nutrient enrichment. The treated wastewater from ETE TRES FRONTEIRAS likely discharges into a local watercourse that flows toward the Atlantic Ocean, contributing to the broader drainage basin of the Paraná River system. The region's aquatic ecosystems depend on maintaining low nutrient levels to prevent eutrophication and support biodiversity. The plant's secondary treatment helps mitigate these risks.
Environmental context
The plant's effluent enters a local stream that is part of the Paraná River basin, which ultimately drains into the Rio de la Plata estuary and the Atlantic Ocean. The coastal proximity (within 10 km) means that nutrients and pollutants from the discharge could affect sensitive coastal ecosystems, including mangroves and estuarine habitats that support diverse aquatic life. Maintaining secondary treatment is crucial to minimize ecological impacts.
