Overview
ETE Mirante BA is a secondary treatment plant serving Mirante, Bahia, Brazil. It discharges 14.03 MLD of treated wastewater, supporting local sanitation needs.
ETE Mirante BA is a municipal wastewater treatment plant located in Mirante, a municipality in the state of Bahia, Brazil. The plant serves a population of approximately 1,030 people, providing secondary treatment to manage domestic wastewater from the community. It is situated in the northeastern region of Brazil, an area characterized by a semi-arid climate and seasonal rainfall patterns. The plant operates with secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and the National Water Resources Policy), treatment plants of this scale are expected to meet effluent quality standards for discharge into water bodies. The plant's discharge volume is 14.03 megaliters per day, indicating a consistent flow from the served population. The treated effluent is discharged into local watercourses that eventually drain into the Atlantic Ocean via the Contas River basin or adjacent coastal basins. The receiving environment supports aquatic life and is part of the broader watershed that sustains local agriculture and biodiversity. Proper treatment helps protect downstream water quality and public health in the region.
Environmental context
The plant discharges into local streams that flow into the Contas River basin, which ultimately reaches the Atlantic Ocean near the coast of Bahia. The region's semi-arid climate means water resources are limited, making effluent quality crucial for maintaining aquatic ecosystems and supporting downstream uses such as irrigation and livestock watering.
