Optimisation toolbox for placement of isolation valves in a water distribution network.

Abstract

In a water distribution system, valves are essential for flow control and subsystem isolation. To repair one of them, subsystem isolation is necessary, which can be accomplished by shutting down nearby valves. The idea of “Segment” is required to assess the function of valves. When a pipe fails, nearby valves are closed to isolate the nodes and pipes that make up a segment from one another. The identification of segments in a water distribution system using an effective algorithm is suggested. Additionally, isolating a segment may result in the segment isolation cutting off another subsystem from water sources. It is an unintentional topological separation. A water distribution system’s dependability is increased by strategically placing valves Keywords: Water Distribution Network (WDN); valves; segments; pipes
