ETE PRAIA BELLA Wastewater Treatment Plant, Mata de São João, Bahia

ETE PRAIA BELLA is a wastewater treatment plant located in Açu da Torre, Mata de São João, in the state of Bahia, Brazil. Situated within the Metropolitan Region of Salvador, this facility serves a small population of 691 residents, reflecting its role in a coastal community. The plant operates under Brazil's national environmental regulations, which set standards for wastewater treatment and discharge to protect water quality. The plant provides secondary treatment, a standard level that removes organic matter and suspended solids. The plant's discharge volume of 20.87 indicates its operational scale. As a facility in a coastal area, it is subject to stringent requirements to prevent marine pollution, aligning with Brazil's CONAMA resolutions that govern effluent discharge into sensitive environments. The treated effluent from ETE PRAIA BELLA is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The coastal waters near Mata de São João support diverse marine life and are important for local fisheries and tourism. Proper treatment at this plant helps protect the ecological health of the region's beaches and coastal ecosystems, which are vital for both biodiversity and the local economy.

The plant discharges into the coastal watershed of Bahia, with the treated effluent eventually reaching the Atlantic Ocean. This coastal region supports mangroves, coral reefs, and seagrass beds, which are sensitive to nutrient pollution. Effective secondary treatment reduces the risk of eutrophication and protects the ecological integrity of the nearshore marine environment, which is important for local biodiversity and tourism.
