ETE Caracol Wastewater Treatment Plant - Caracol, Mato Grosso do Sul, Brazil

ETE Caracol is a municipal wastewater treatment plant located in Caracol, a town in the state of Mato Grosso do Sul, Brazil. The plant serves a small population of 371 residents, reflecting its role in a rural or small urban community. As part of Brazil's wastewater infrastructure, it contributes to public health and environmental protection in the region. The plant provides secondary treatment, which is the standard biological process required for most municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological degradation of organic matter, reducing biochemical oxygen demand and suspended solids. The plant discharges approximately 40.67 m³/day of treated effluent, indicating a modest scale consistent with the small population served. The treated effluent from ETE Caracol is discharged into a local watercourse, ultimately draining into the Paraguay River basin, part of the larger Paraná River system. This inland watershed supports diverse aquatic life and is important for regional agriculture and water supply. The plant's operation helps protect downstream water quality in this ecologically sensitive basin.

ETE Caracol discharges into a tributary of the Paraguay River basin, which flows through the Pantanal region, one of the world's largest tropical wetlands. The Pantanal supports a rich diversity of flora and fauna, including migratory birds and aquatic species. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding this critical ecosystem from eutrophication and habitat degradation.
