ETE WALITA Wastewater Treatment Plant, Varginha, Minas Gerais, Brazil

ETE WALITA is a municipal wastewater treatment plant located in the industrial district of Varginha, in the state of Minas Gerais, Brazil. The plant serves a small population of 814 people, reflecting its role in a localized community within the broader Varginha region. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for most urban wastewater. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant discharges 103.68 m³/day of treated effluent. The treated effluent from ETE WALITA is released into local water bodies that drain into the Rio Grande basin, a major tributary of the Paraná River system. This river network flows through southeastern Brazil and ultimately reaches the Río de la Plata estuary. The plant's operation helps protect downstream water quality in a region characterized by agricultural and industrial activity.

ETE WALITA discharges into local streams that feed the Rio Grande, a key river in the Paraná basin. The Rio Grande flows into the Paraná River, which empties into the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The plant's secondary treatment reduces organic pollution, helping to maintain ecological balance in the downstream environment.
