ETE ITAJU DO COLONIA is a municipal wastewater treatment plant located in Itaju do Colônia, a municipality in the state of Bahia, Brazil. The plant serves a population of approximately 4,838 residents, placing it in the small agglomeration category under Brazilian wastewater management frameworks. It operates in the Nordeste region, an area characterized by tropical climate and seasonal rainfall patterns. The plant provides secondary treatment, which is the standard level required for urban wastewater in Brazil under the National Environmental Council (CONAMA) resolutions and the National Basic Sanitation Law (Law 11.445/2007). Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is likely discharged into a local watercourse within the drainage basin of the Atlantic coast, as the plant is located about 15 km inland from the coast. The region's rivers flow eastward into the Atlantic Ocean, supporting diverse aquatic ecosystems. The plant plays a key role in protecting downstream water quality and public health in the Ilhéus-Itabuna region.
Environmental context
The plant is situated in the watershed of the Atlantic coast of Bahia, approximately 15 km from the ocean. Treated effluent likely enters a tributary of the Rio de Contas or a smaller coastal river system, eventually reaching the Atlantic Ocean. The downstream environment includes coastal ecosystems such as mangroves and estuaries, which are ecologically sensitive and support diverse marine life. Proper treatment helps prevent nutrient pollution and protects these habitats.
