ETE 2 Cambara Wastewater Treatment Plant, São Pedro do Ivaí, Paraná, Brazil

ETE 2 Cambara is a municipal wastewater treatment facility located in São Pedro do Ivaí, within the state of Paraná, Brazil. The plant serves a population of around 4,500 residents, reflecting its role in managing domestic wastewater for a small community in the southern region of the country. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for inland water bodies. This process typically involves biological treatment to reduce organic matter and suspended solids, ensuring the effluent meets quality standards before discharge. The plant handles an average daily flow of 367.20 cubic meters. The treated effluent is released into a local watercourse that eventually drains into the Ivaí River basin, a tributary of the Paraná River. The Paraná River flows into the Río de la Plata estuary, making the plant's operations important for downstream water quality in one of South America's major river systems.

The plant discharges into a small watercourse that feeds into the Ivaí River, which flows through the Paraná state and joins the Paraná River. The Paraná River is a major waterway that ultimately reaches the Río de la Plata estuary. The local watershed supports diverse aquatic life and is used for agriculture and water supply. Proper treatment helps protect downstream ecosystems from nutrient pollution and pathogens.
