Asset Management of Sewerage Business


What is asset management?

Asset management is the process of planning, managing and implementing construction and maintenance operations to gain the maximum effect from assets (facilities) that are owned by organizations. When creating this scheme, an understanding of the present status of service and an estimate of potential operational risks are required. This is then followed by determining the standards for establishing the target objective and priorities of operations. The final step is implementation of continued improvements.


Japan’s first ISO 55001 asset management system certification

The pipeline division of Sendai City’s sewerage department received Japan’s first international standard ISO 55001 Asset Management System Certification in FY 2013. Improvement of most of the sewage facilities in Sendai had been completed by FY 2008. In future, it will be necessary to promote measures against disasters such as earthquakes and inundation in addition to facility maintenance and renovation. In spite of limitations to budgets and personnel resources, by utilizing asset management we prioritize the most important projects and estimate cost over the long term. By doing this we run projects steadily and efficiently, and ensure the safety of the facilities.

Investigations so far indicate that sewage pipes can be used for about 1.5 times their standard service life and sewage facilities about 1.5-2 times theirs. We predict that reducing the number of renewals will lead to a reduction in costs. Immediately after the disaster, we were able to efficiently survey the damage using the asset management system.


Conveying experiences and lessons learned to the world
