ETE SEDE ALFREDO CHAVES - Secondary Wastewater Treatment Plant in Anchieta, Brazil

ETE SEDE ALFREDO CHAVES is a municipal wastewater treatment facility located in Anchieta, in the state of Espírito Santo, Brazil. The plant serves a small community of 448 residents, providing secondary treatment to domestic wastewater. It is situated inland, more than 10 km from the coast, but within 50 km of the Atlantic Ocean. The plant operates with secondary treatment, which is appropriate for its small scale. Under Brazilian regulations, wastewater treatment plants are subject to CONAMA resolutions and state-level environmental permits. For a plant of this size, secondary treatment meets the typical requirements for organic matter and solids removal before discharge. The treated effluent is discharged into local water bodies that eventually drain into the Atlantic Ocean. The region's watershed supports diverse aquatic life and contributes to the coastal ecosystem of southeastern Brazil. Proper treatment helps protect downstream water quality and public health.

The plant discharges into local streams that flow toward the Atlantic Ocean, part of the coastal watershed of Espírito Santo. The receiving waters support aquatic biodiversity and are important for local fisheries and recreation. The region's tropical climate and proximity to the coast make water quality management critical for maintaining healthy ecosystems.
