ETE LABOREAUX Wastewater Treatment Plant, Itabira, Minas Gerais, Brazil

ETE LABOREAUX is a wastewater treatment plant located in Itabira, a city in the state of Minas Gerais, Brazil. The plant serves a population of around 42,647 residents, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. Itabira is situated in the southeastern region of Brazil, an area characterized by its mountainous terrain and historical mining activities. Brazil's wastewater treatment facilities are regulated under the National Water Resources Policy (Law 9.433/1997) and the National Environmental Council (CONAMA) resolutions, which set discharge standards for treated effluent. For agglomerations of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant's operational details, including treatment process and capacity, are part of the municipal sanitation framework managed by local authorities. The treated effluent from ETE LABOREAUX is discharged into local water bodies that ultimately drain into the Doce River basin. The Doce River flows eastward to the Atlantic Ocean, passing through ecologically sensitive areas that support diverse aquatic life. Proper treatment at this plant helps protect downstream water quality and the health of the riverine ecosystem.

ETE LABOREAUX discharges into tributaries of the Doce River basin, which flows into the Atlantic Ocean. The Doce River watershed supports a variety of fish species and is an important water resource for communities and industries in Minas Gerais and Espirito Santo. The region's aquatic ecosystems benefit from effective wastewater treatment that reduces nutrient and pollutant loads.
