Many water suppliers in Japan are required to renew aged waterworks facilities systematically in spite of the decline in revenues due to the decrease in the population. Moreover, they are needed to build waterworks facilities with high earthquake resistance. Therefore, it is necessary for water suppliers to manage waterworks effectively and efficiently in order to build sustainable waterworks. In this paper, to support sound business management, a method of water asset management is arranged systematically. And also an actual example with this systematic method in a water supplier is introduced in which reduction of renewal costs by optimization of ability of the waterworks facilities and setting renewal cycle standards is explained. Furthermore, a perspective of renewal costs taking into account the acceleration of earthquake-resistance strengthening plan and equalization of renewal demands is shown.
