ETE SOTECO Wastewater Treatment Plant, Viana, Espirito Santo, Brazil

ETE SOTECO is a municipal wastewater treatment plant located in the Soteco neighborhood of Viana, within the Greater Vitoria metropolitan region of Espirito Santo, Brazil. The plant serves a population of 1,779 and operates at a secondary treatment level, which is appropriate for small agglomerations under Brazilian regulatory standards. The plant discharges an average of 235.01 cubic meters of treated wastewater per day. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the basic requirements for inland and coastal discharge set by Brazil's National Environmental Council (CONAMA) resolutions. The plant's coastal proximity subjects it to additional environmental oversight. The treated effluent from ETE SOTECO ultimately drains into the Atlantic Ocean via local watercourses in the Vitoria estuarine system. This coastal region supports diverse marine life and is an important ecological and economic zone for Espirito Santo. Proper treatment helps protect water quality in the receiving bays and beaches.

ETE SOTECO discharges into the coastal watershed of Espirito Santo, with treated effluent flowing through local streams into the Vitoria Bay estuary and eventually the South Atlantic Ocean. The region's coastal ecosystems, including mangroves and sandy beaches, are sensitive to nutrient pollution and require effective wastewater treatment to maintain water quality and support fisheries and tourism.
