ETE PRIMAVERA DO LESTE - Wastewater Treatment Plant in Primavera do Leste, Mato Grosso, Brazil

ETE PRIMAVERA DO LESTE is a wastewater treatment plant located in Primavera do Leste, a city in the state of Mato Grosso, Brazil. The plant serves a population of approximately 27,074 people, placing it in the medium-agglomeration category for Brazilian wastewater infrastructure. It is situated in the Central-West region, an area characterized by tropical climate and agricultural activity. Brazil's wastewater treatment facilities are regulated under the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy (Law 9.433/1997). For agglomerations of this scale, secondary treatment is typically required to reduce organic load and protect water quality. It operates within this regulatory framework. The plant discharges treated effluent into local water bodies that drain into the Paraná River basin, eventually reaching the Rio de la Plata estuary. The surrounding region includes the Cerrado biome, a biodiversity hotspot, and the plant's operations are important for protecting downstream aquatic ecosystems and water resources used for agriculture and human consumption.

The plant's treated effluent flows into local streams that are part of the Paraná River basin, one of South America's major river systems. The Paraná River ultimately discharges into the Rio de la Plata estuary, which supports diverse aquatic life and is an important ecological and economic resource. The Cerrado biome surrounding Primavera do Leste is a critical watershed area, and proper wastewater treatment helps prevent nutrient pollution and protect downstream water quality.
