ETE Itapirapua Paulista - Secondary Wastewater Treatment Plant in Itapirapuã Paulista, São Paulo

ETE Itapirapua Paulista is a municipal wastewater treatment plant located in Itapirapuã Paulista, a small town in the state of São Paulo, Brazil. The plant serves a population of 1,343 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required for most urban wastewater in Brazil under federal regulations (CONAMA resolutions). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant discharges approximately 147.89 m³/day of treated effluent. The treated effluent is released into local water bodies that drain into the Paraná River basin, one of the most important river systems in South America. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region's rivers and streams.

The plant discharges into local streams that are part of the Paraná River basin, which flows through southeastern Brazil and eventually reaches the Río de la Plata estuary. The region's watershed supports diverse aquatic life and is important for local agriculture and water supply. Proper treatment helps prevent nutrient pollution and maintains ecological balance in these sensitive freshwater systems.
