ETE Campina do Monte Alegre - Secondary Wastewater Treatment Plant in Buri, São Paulo

ETE Campina do Monte Alegre is a wastewater treatment plant located in the rural area of Buri, in the state of São Paulo, Brazil. The plant serves a population of 3,545 people, reflecting a small-scale municipal facility typical of smaller communities in the region. It is situated near the Rodovia Engenheiro Lauri Simões de Barros in the Aracaçu district. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland wastewater discharges. Secondary treatment effectively removes organic matter and suspended solids, reducing the environmental impact on receiving water bodies. The plant's discharge volume is 444.62 m³/day, indicating a modest flow consistent with the population served. The treated effluent is discharged into local watercourses that are part of the Paraná River basin, one of the largest and most ecologically significant river systems in South America. The plant's inland location, far from the coast, means its discharge contributes to freshwater ecosystems rather than marine environments. Proper treatment helps protect downstream water quality and aquatic life in the region's rivers and streams.

The plant discharges into local streams that flow into the Paranapanema River, a major tributary of the Paraná River. The Paraná River basin supports diverse aquatic ecosystems, including floodplain wetlands and riparian forests, and is an important corridor for migratory fish species. The region's subtropical climate and agricultural land use make effective wastewater treatment crucial for preventing nutrient pollution and maintaining water quality in downstream reservoirs and rivers.
