  Drinking water supply and distribution systems are critical infrastructure
that has to be well maintained for the safety of the public. One important tool
in the maintenance of water distribution systems (WDS) is flushing. Flushing is
a process carried out in a periodic fashion to clean sediments and other
contaminants in the water pipes. Given the different topographies, water
composition and supply demand between WDS no single flushing strategy is
suitable for all of them. In this report a non-exhaustive overview of
optimization methods for flushing in WDS is given. Implementation of
optimization methods for the flushing procedure and the flushing planing are
presented. Suggestions are given as a possible option to optimise existing
flushing planing frameworks.
