ETE Santa Ines Wastewater Treatment Plant, Santa Ines, Bahia, Brazil

ETE Santa Ines is a wastewater treatment plant located in Santa Ines, Bahia, Brazil, serving a population of around 6,150. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids from wastewater before discharge. As a secondary treatment facility, ETE Santa Ines meets the basic requirements for municipal wastewater treatment in Brazil, where national regulations set effluent standards for organic load and solids. The plant's discharge volume is approximately 416 cubic meters per day, indicating a scale consistent with a small community. The treated effluent from ETE Santa Ines is discharged into local water bodies, likely tributaries of the Jequiriça River, which flows through the region. This river system drains into the Atlantic Ocean, supporting aquatic ecosystems and downstream communities. Proper treatment helps protect water quality in this ecologically sensitive area.

The plant discharges into the Jequiriça River basin, which flows through Bahia's coastal lowlands before reaching the Atlantic Ocean. This watershed supports diverse aquatic life and provides water for local agriculture and communities. The region's tropical climate and seasonal rainfall patterns influence river flow and dilution capacity, making consistent treatment important for maintaining downstream water quality.
