ETE 2 LAGOA FORMOSA - Secondary Wastewater Treatment Plant in Lagoa Formosa, Minas Gerais

ETE 2 LAGOA FORMOSA is a wastewater treatment plant located in Lagoa Formosa, a municipality in the state of Minas Gerais, Brazil. The plant serves a population of approximately 3,191 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations, including CONAMA resolutions, secondary treatment is typically required for urban wastewater to protect receiving water bodies. The plant discharges an average of 402.55 cubic meters of treated effluent per day. The treated effluent from ETE 2 LAGOA FORMOSA is released into local watercourses that drain into the Paranaíba River basin, part of the larger Paraná River system. This river network supports diverse aquatic ecosystems and provides water for downstream communities and agriculture in southeastern Brazil.

The plant's discharge enters local streams that flow into the Paranaíba River, a major tributary of the Paraná River system. This watershed supports diverse freshwater habitats and is important for regional water supply and irrigation. The area's tropical climate and agricultural land use mean that nutrient loading from wastewater can affect downstream water quality, making secondary treatment essential for protecting aquatic life and preventing eutrophication.
