Riverbank filtration (RBF) is a well proven treatment which, at numerous sites, is part of a multi barrier concept in drinking water supply. In Düsseldorf, for instance, bank filtrate has been discharged from wells close to the bank of the Rhine since 1870. RBF is a process during which surface water is subjected to subsurface flow prior to extraction from vertical or horizontal wells. From a water resources perspective, RBF is characterised by an improvement in water quality, which in general is based on a combination sorptive‐filtration and biodegradation.
