Richmond Skeleton Network

Network description

The Richmond skeleton network is a reduced network of the Richmond network used in a wide range of papers. The network is equipped with seven fixed speed pumps and six storage tanks. The network has no loops that allow bidirectional flow, but five loops with pumps or control valves. There are eight control valves. The netwrok is available here: Exeter uni .inp file
