Abstract: A method is disclosed for use in the design of a water distribution by determining whether to locate a pressure reducing valve (PRV) in a given location comprising the steps of: (a) determining the benefit arising from reduced water leakage achieved by locating a PRV in that location; (b) determining the benefit arising from reduced pipe burst frequency achieved by locating a PRV in that location; (c) determining the benefit arising from at least one other parameter achieved by locating a PRV in that location; (d) determining the cost associated with locating a PRV at that location; (e) calculating a net benefit value using the benefits and costs determined in steps (a) to (d); and (f) locating a PRV in that location if the calculated net benefit value exceeds a predetermined value. Also disclosed is a control method for use in the evaluation of faults, the method comprising the steps of: (a) receiving a fault notification; (b) determining from the fault notification a series of potential causes of the notified fault; (c) determining, for each potential cause, an impact evaluation; (d) aggregating the impact evaluations for each potential cause to derive an importance indication for the notified fault.
