ETE NOVAIS Wastewater Treatment Plant, Novais, São Paulo

ETE NOVAIS is a municipal wastewater treatment plant located in Novais, a city in the state of São Paulo, Brazil. The plant serves a population of around 4,130 residents, providing essential sanitation services for this small community in the southeastern region of the country. The plant operates at the secondary treatment level, which is the standard required by Brazilian regulations (CONAMA resolutions) for urban wastewater treatment. This level of treatment effectively removes organic matter and suspended solids, ensuring that the effluent meets basic quality standards before discharge. The plant handles an average daily flow of approximately 793 cubic meters. The treated effluent is discharged into local water bodies, contributing to the protection of the Rio Preto basin and downstream ecosystems. By treating wastewater to secondary standards, ETE NOVAIS helps maintain water quality in the region, supporting aquatic life and reducing pollution loads that would otherwise impact the broader Paraná River system.

The plant discharges into the Rio Preto watershed, which flows into the Grande River and eventually the Paraná River basin. This region supports diverse aquatic habitats and is important for local agriculture and water supply. Secondary treatment reduces organic pollution, helping to maintain ecological balance in these downstream water bodies.
