Overview
ETE Rubineia is a secondary wastewater treatment plant serving 1,962 people in Rubineia, Sao Paulo, Brazil. It discharges 337.82 m3/day of treated effluent near the coast.
ETE Rubineia is a municipal wastewater treatment plant located in Rubineia, a city in the state of Sao Paulo, Brazil. The plant serves a population of approximately 1,962 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process required for most municipal wastewater in Brazil. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant discharges an average of 337.82 cubic meters of treated wastewater per day. The treated effluent from ETE Rubineia is discharged into local water bodies that ultimately drain into the Parana River basin, one of South America's major river systems. The plant's proximity to the coast (within 10 km) means its discharge can influence coastal water quality, making proper treatment essential for protecting downstream aquatic ecosystems and supporting regional water resource management.
Environmental context
The plant discharges into the Parana River basin, which flows through southeastern Brazil and eventually reaches the Rio de la Plata estuary. The coastal proximity means treated effluent can affect nearshore marine environments, including areas that support diverse aquatic life and local fisheries. Proper secondary treatment helps reduce nutrient loading and organic pollution, which is critical for maintaining water quality in this ecologically sensitive region.
