Overview
ETE Adolfo Viana is a secondary treatment plant serving Curaçá, Bahia, Brazil. It discharges 730.61 m³/day of treated wastewater, protecting local water resources in the semi-arid Nordeste region.
ETE Adolfo Viana is a municipal wastewater treatment plant located in Curaçá, a city in the state of Bahia, Brazil. The plant serves a population of approximately 8,464 residents, making it a small-scale facility within the regional sanitation infrastructure of the Nordeste region. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. Secondary treatment aligns with Brazilian regulatory standards (CONAMA resolutions) for inland discharge. The plant operates under Brazil's national water quality framework, which requires adequate treatment to protect receiving water bodies. The treated effluent volume is 730.61 m³/day. The plant's discharge contributes to the local watershed, which ultimately drains into the São Francisco River basin, a major river system in northeastern Brazil. Proper treatment is essential to safeguard water quality in this semi-arid region, where water resources are critical for agriculture, drinking water, and ecosystem health.
Environmental context
The plant discharges into the São Francisco River basin, one of Brazil's most important river systems, flowing through the semi-arid Caatinga biome. The river supports diverse aquatic life, including endemic fish species, and provides water for irrigation and human consumption. Downstream, the São Francisco River reaches the Atlantic Ocean, making the plant's secondary treatment crucial for preventing nutrient pollution and maintaining ecological balance in this water-stressed region.
