ETE PEDRALVA Wastewater Treatment Plant, Pedralva, Minas Gerais

ETE PEDRALVA is a municipal wastewater treatment plant located in Pedralva, a city in the state of Minas Gerais, Brazil. The plant serves a population of about 5,251 people, reflecting its role in managing domestic wastewater for this small agglomeration in the southeastern region of the country. The plant provides secondary treatment, which is the standard biological process required under Brazilian regulations for communities of this size. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The plant discharges approximately 604.80 cubic meters of treated wastewater daily. The treated effluent from ETE PEDRALVA is discharged into local water bodies that ultimately drain into the Rio Grande basin, part of the larger Paraná River system. This river network supports diverse aquatic life and provides water for agricultural and urban uses downstream. Proper treatment at this plant helps protect water quality in the region's freshwater ecosystems.

The plant discharges into local streams that flow into the Rio Grande, a major tributary of the Paraná River basin. This watershed supports diverse aquatic habitats and is important for regional water supply and agriculture. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain the ecological health of downstream water bodies.
