ETE VILA OASIS Wastewater Treatment Plant, Cariacica, Espírito Santo

ETE VILA OASIS is a wastewater treatment plant located in the Tucum neighborhood of Cariacica, within the Greater Vitória metropolitan region of Espírito Santo, Brazil. The plant serves a small population of 435 residents and operates with secondary treatment, which is the standard level for municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. With a discharge volume of 60.48 m³/day, the plant is designed for a small community. Brazilian environmental regulations, such as CONAMA Resolution 430/2011, set effluent standards for such facilities. The treated effluent is discharged into local water bodies that drain into the Atlantic Ocean, given the plant's proximity to the coast. The region's watershed includes the Santa Maria da Vitória River and other streams that flow into Vitória Bay, an ecologically important estuary supporting mangroves and diverse aquatic life.

The plant discharges into the Vitória Bay watershed, which drains into the Atlantic Ocean. Vitória Bay is a coastal estuary that supports mangroves, fish nurseries, and migratory birds. The region's tropical climate and urban development make proper wastewater treatment critical to prevent nutrient pollution and protect marine biodiversity.
