Abstract

Under depopulation, a policy shift is required for efficient operation of the water distribution system. In particular, issues regarding the sustainability of local water distribution systems are being raised, and this mainly deals with issues of rates and costs. Local governments that are experiencing problems such as decreased tax revenue due to depopulation are in a situation where it is difficult to fulfill the responsibility of local water distribution systems in the era of local decentralization. Compared to regions that directly benefit from wide-area water distribution systems such as dams, other local cities are experiencing problems of high rates and low realization rates. This phenomenon accelerates the deterioration of financial soundness, making local water supply responsibility more difficult. Therefore, this study quantified the relationship between hydraulic and water quality factors and depopulation in local water distribution systems and analyzed this to examine the appropriateness of potential disruption of infrastructure availability to increase user usability and resolve inequality in local water distribution systems.

최근 인구 감소 시대를 맞이하여 물 분배 시스템의 효율적 운영을 위한 정책 전환이 요구되고 있다. 특히 지방상수도의 지속가능성에 대한 문제점이 제시되고 있으며, 이는 요금 및 비용 문제를 다루게 된다. 인구가 감소함에 따라 세입 감소 등의 문제를 겪고 있는 지자체는 지방분권 시대에 지방상수도 운영 책무를 다하기 어려운 상황에 처해 있다. 댐 등 광역상수도의 혜택을 직접적으로 받는 지역에 비해, 타 지방도시에서는 높은 요금과 낮은 현실화율 문제가 발생한다. 이러한 현상은 재정 건전성 악화를 가속화시키고, 이로 인해 지방상수도 공급 책무를 더욱 어렵게 만든다. 따라서 본 연구에서는 지방상수도 이용자의 인구감소에 따른 수리 및 수질 인자와 인구감소 간의 관계를 정량화하였으며, 이를 분석하여 지방상수도의 사용성 증대 및 불평등 해소를 위해 인프라의 잠재적 가용중단의 적정성을 검토하였다.
