ETE CRAVOLANDIA Wastewater Treatment Plant, Santa Inês, Bahia

ETE CRAVOLANDIA is a wastewater treatment plant located in Santa Inês, Bahia, Brazil. It serves a population of approximately 2,198 people, making it a small-scale facility in the northeastern region of the country. The plant is situated inland, away from coastal areas, and plays a key role in managing municipal wastewater for the local community. The plant provides secondary treatment, which is the standard level required for most urban wastewater in Brazil under the National Environmental Council (CONAMA) resolutions. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Brazilian regulations for small agglomerations often mandate secondary treatment to protect water quality in receiving bodies. The treated effluent from ETE CRAVOLANDIA is discharged into a local watercourse, which eventually drains into the Atlantic Ocean via the broader river network of Bahia. The region's watershed supports diverse aquatic life and is important for local agriculture and communities. Proper treatment helps prevent eutrophication and maintains the ecological health of downstream environments.

The plant discharges into a local river system that flows through the Bahia interior before reaching the Atlantic Ocean. This watershed supports diverse aquatic species and provides water for irrigation and domestic use. Effective secondary treatment reduces organic pollution and nutrient loading, safeguarding downstream ecosystems and water quality for communities.
