This study provides the economical plan of transmission and distribution line in order to make the most effect investment to the waterworks for the stabilized water supply. When it come down to the planning of pipeline, it is profitable that the pipe line is located on-the center of the demand area with considering surveying of roads. And the result of the evaluation indicates that high-impact pipe, ductile cast iron pipe and steel pipe are the most desirable pipes. In the designing of the pipeline, the diameter should be selected with considering of the regional condition and water consumption. It was found that the variation of maintenance-cost with increasing of pumping and electric supply is more important factor of the total-cost that the variation of construction-cost. The strategy of system for the stabilized water supply must be based on the double conveying pipe line, the searching for the headwaters, the use of recycling water at wastewater treatment plant, the improvement of the decrepit waterworks and system development and automation plan.
