ETE Divinolândia - Secondary Wastewater Treatment Plant in Divinolândia, São Paulo

ETE Divinolândia is a municipal wastewater treatment plant located in Divinolândia, São Paulo, Brazil. The plant serves a population of approximately 5,883 residents, classifying it as a small agglomeration under Brazilian wastewater management frameworks. It is situated inland, away from coastal areas, and operates within the state's regulatory environment. The plant provides secondary treatment, which is the standard biological treatment level required for municipal wastewater in Brazil. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant discharges an average of 851.57 m³ of treated effluent per day. The treated effluent from ETE Divinolândia is released into a local watercourse that ultimately drains into the Rio Pardo basin, part of the larger Paraná River system. This river network supports diverse aquatic life and provides water for downstream communities and agriculture. Proper treatment helps protect water quality and ecological balance in the region.

The plant discharges into a tributary of the Rio Pardo, which flows into the Rio Grande and eventually the Paraná River, one of South America's major river systems. The downstream environment includes agricultural areas and small communities that rely on these waters. Effective secondary treatment reduces organic load and pathogens, safeguarding aquatic habitats and human uses.
