ETE Florinia Wastewater Treatment Plant, Florínea, São Paulo, Brazil

ETE Florinia is a municipal wastewater treatment plant located in Florínea, a city in the state of São Paulo, Brazil. The plant serves a population of about 2,081 people, reflecting its role in a small community within the Região Imediata de Assis. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under Brazil's national environmental regulations, which set standards for wastewater treatment and discharge. For small agglomerations like Florínea, secondary treatment is the typical requirement to protect water quality. The plant's discharge volume is recorded at 324.97 cubic meters, indicating its operational scale. The treated effluent is released into local water bodies that drain into the Paraná River basin, a major hydrological system in South America. This basin supports diverse aquatic ecosystems and is important for regional water supply and agriculture. The plant's operation helps maintain the ecological health of downstream waters by reducing pollutant loads.

The plant's discharge enters local streams that flow into the Paranapanema River, a tributary of the Paraná River. The Paraná River basin is one of the largest in South America, hosting rich biodiversity including migratory fish species. The surrounding region is primarily agricultural, with sugarcane and grains, making nutrient management critical to prevent eutrophication in downstream reservoirs and wetlands.
