ETE Carneirinho Sede - Secondary Wastewater Treatment in Carneirinho, Minas Gerais

ETE Carneirinho Sede is a municipal wastewater treatment facility located in Carneirinho, a city in the state of Minas Gerais, Brazil. The plant serves a population of about 6,900 residents, classifying it as a small agglomeration under Brazilian wastewater management frameworks. It is situated in the southeastern region of the country, near the border with the state of Mato Grosso do Sul. The plant provides secondary treatment, which is the standard level required by Brazilian regulations (CONAMA Resolution 430/2011) for inland water bodies. As a secondary treatment plant, it typically uses biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into a local water body, likely a tributary of the Paraná River basin, which ultimately flows into the Río de la Plata estuary. The plant's proximity to the coast (within 10 km) means its discharge may influence downstream aquatic ecosystems, including sensitive wetlands and coastal zones that support diverse fish and bird species.

The plant discharges into a water body within the Paraná River basin, one of South America's largest drainage systems. The basin supports extensive wetlands, floodplains, and riparian forests that provide critical habitat for migratory birds and aquatic species. Downstream, the river system feeds the Río de la Plata estuary, a highly productive ecosystem that sustains fisheries and biodiversity. The plant's secondary treatment helps protect these environments from excessive nutrient loading and organic pollution.
