ETE Catanduva Wastewater Treatment Plant, Catanduva, São Paulo, Brazil

ETE Catanduva is a wastewater treatment plant located in Catanduva, São Paulo, Brazil, serving a population of around 109,908. Situated in the southeastern region of the country, the plant is a key component of the local sanitation infrastructure. As a facility serving a population of this scale, ETE Catanduva is expected to comply with Brazilian federal regulations, including CONAMA resolutions and the National Basic Sanitation Plan (PLANSAB). These regulations typically require secondary treatment for urban wastewater, with potential for advanced treatment if the receiving water body is sensitive. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a substantial treatment capability. The treated effluent from ETE Catanduva is discharged into local water bodies that ultimately drain into the Paraná River basin, one of the most important river systems in South America. The downstream environment supports diverse aquatic life and is used for water supply, agriculture, and recreation. Proper treatment is essential to protect water quality in this ecologically and economically significant watershed.

The plant discharges into the Paraná River basin, which flows through southeastern Brazil and into the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems and is a critical water resource for millions of people. Downstream environments include wetlands and floodplains that provide habitat for fish and migratory birds, making effective wastewater treatment vital for maintaining ecological balance.
