ETE Centralina Wastewater Treatment Plant - Centralina, Minas Gerais, Brazil

ETE Centralina is a municipal wastewater treatment plant located in Centralina, within the state of Minas Gerais, Brazil. Serving a population of 979, the plant is part of the local sanitation network that manages domestic wastewater for this small community in the southeastern region of the country. As a secondary treatment facility, ETE Centralina provides biological treatment to reduce organic matter and suspended solids before discharge. Under Brazil's national environmental regulations, such plants must comply with CONAMA standards for effluent quality, ensuring treated water meets permissible limits for receiving water bodies. The plant's treated effluent is discharged into local streams that drain into the Paranaíba River basin, a major tributary of the Paraná River system. This waterway ultimately flows into the Río de la Plata estuary, supporting diverse aquatic ecosystems and agricultural water use downstream.

The Paranaíba River basin, part of the larger Paraná River system, receives treated effluent from ETE Centralina. This basin supports important aquatic habitats and is a key water source for agriculture and communities in the region. The Paraná River flows into the Río de la Plata, an ecologically sensitive estuary that sustains fisheries and migratory species.
