 This method of filtration is still being used today for the treatment of a large part of the raw material, now water from the Albert Canal.In 1930, the concession came to an end, as no agreement could be reached with the English owners concerning a new construction in which the municipalities surrounding Antwerp would be included.The city of Antwerp took over the company and founded a mixed intermunicipal company (private and public participation) in which the English Waterworks kept a minority participation.
