Aquafin was established in 1990 by the government of Flanders. Its mission is to design, finance, build and operate all supramunicipal infrastructure needed to treat domestic wastewater and to optimise all main sewers and wastewater treatment plants taken over from the Flemish Environmental Agency.
The Flemish Environmental Holding is the sole shareholder in Aquafin.
Besides its extensive supramunicipal task, Aquafin also offers its services to the Flemish municipalities, the industry in Flanders and abroad.
