Abstract
Water utilities are reaching a stage of improvement and renewal of aging facilities and pipelines. In addition, improving the quality of water services, such as gaining adequate water pressure, maintaining water quality in distributed water and establishing of countermeasures against an earthquake disaster or a drought etc., is also required. In order to meet these needs of improving water supply system with limited financial resources, it is necessary to rationally evaluate the functions of the water system and establish the project priorities, considering present and future conditions.
This paper proposed a methodology to evaluate the functions of the distribution water mains to help with the planning of the improvement and renewal of water supply networks, and showed a case study applying this methodology.
