ETE Livramento de Nossa Senhora is a wastewater treatment facility located in Livramento de Nossa Senhora, a municipality in the state of Bahia, Brazil. The plant serves a population of approximately 10,891 residents, classifying it as a small to medium agglomeration under Brazilian sanitation standards. It operates secondary treatment, which is the minimum required for most urban areas under Brazil's national environmental regulations. The plant's treatment process is secondary, typically involving biological treatment to reduce organic matter and suspended solids. The reported discharge volume of 855.62 cubic meters per day suggests a scale consistent with the population served. In Brazil, wastewater treatment plants of this size are regulated by state environmental agencies, such as the Instituto do Meio Ambiente e Recursos Hídricos (INEMA) in Bahia, and must comply with federal CONAMA resolutions on effluent quality. The treated effluent is discharged into a local watercourse, likely a tributary of the Rio de Contas basin, which flows through the semi-arid region of Bahia. This river system is ecologically important for local biodiversity and supports downstream communities. Proper treatment helps protect water quality in a region where water resources are often scarce and sensitive to pollution.
Environmental context
The plant discharges into a local watercourse within the Rio de Contas basin, which drains into the Atlantic Ocean near the city of Itacaré. This basin supports diverse aquatic life and is an important water source for agriculture and human consumption in the semi-arid region of Bahia. Secondary treatment reduces organic pollutants, helping to maintain water quality in a watershed that faces pressures from drought and land use changes.
