Overview
ETE Jaguarari is a secondary treatment plant serving about 11,000 people in Jaguarari, Bahia, Brazil. It discharges approximately 760 m³/day of treated wastewater into the local watershed.
ETE Jaguarari is a municipal wastewater treatment plant located in Jaguarari, a city in the state of Bahia, northeastern Brazil. The plant serves a population of approximately 11,000 residents, placing it in the small-to-medium agglomeration category for the region. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for most urban wastewater. With a discharge volume of about 760 cubic meters per day, the facility operates within the typical scale for a community of this size. Brazilian environmental law mandates that treated effluent must meet quality standards before release into water bodies. The treated effluent from ETE Jaguarari is discharged into a local watercourse that eventually drains into the São Francisco River basin, one of Brazil's most important river systems. The São Francisco River flows northward through the semi-arid Sertão region and empties into the Atlantic Ocean. The plant plays a key role in protecting downstream water quality and public health in this ecologically sensitive area.
Environmental context
The plant discharges into a tributary of the São Francisco River basin, which is the fourth-largest river system in South America and a critical water source for northeastern Brazil. The downstream environment includes the semi-arid Caatinga biome, where water resources are scarce and aquatic ecosystems are highly dependent on consistent flow and water quality. The São Francisco River supports diverse fish species and provides irrigation, drinking water, and hydropower for millions of people before reaching the Atlantic Ocean.
