ABSTRACT
ABSTRACT: Kunming is menaced by raw water shortage due to serious drought for several years. The hydraulic model is applied to multiple water reduction dispatch schemes comparison in order to resolve water shortage threat and provide basic supply service at the same time. The trials were carried out in a normal scheme, district turns water supply, and period water reduction by monitoring the flow and pressure of network. The research showed, period water reduction scheme is the best plan for considering the elements of water saving, pressure and flow stability, operability, and supply service guarantee. The scheme made a significant effort when it was implemented, the error of simulated pressure from real time pressure was neglectable and the result was high correlative. The successful case was a good reference for other regions facing raw water shortage crisis. The hydraulic model is worked as a fundamental tool for water supply dispatch supporting.
