Ⅰ. Research Background and Objectives
ㅇ The waterworks and sewerage structures, which have been extensively constructed since the 1970s and the 1990s, respectively, in Korea, will reach the end of their design life in the near future. The management of old and tired structures has become a significant concern in other social overhead capitals such as railroad, highway, and power plants. The aging issue is still to come in the water sector, but the water infrastructures, especially the ones managed by local governments (municipalities), are less prepared for tackling aging problems.
ㅇ In order to bring attention to the aging water infrastructures, authors have assessed the sustainability of the water services and water infrastructures in each municipality since 2014. The assessment results are provided on the Web site (http://wwrd.kei.re.kr/) and is accessible by the public. New water policy strategies or directions such as asset management systems or customers’(residents’) experience management are also reviewed.

Ⅱ. Assessment Results of the Sustainability of Water Services and Water Infrastructures
o The Framework of Sustainability Assessment
ㅇ In 2017, a framework to assess the sustainability of water services and water infrastructures for each municipality was established. The framework includes three pillars - economic, social, and environmental sustainability. For economic sustainability, financial sustainability, cost allocation, and level of assessment management of water services and its management were evaluated. For social sustainability, the fairness of the w
