Waterworks facilities inevitably experience some amount of leakage even if there is a lot of investment or state-of-the-arttechnology that is applied such as DMA(District Metered Area) system construction, leakage detection, repair, piperehabilitation, etc. The primary reason is the leakage is naturally restored over time. In the UK, this restoration characteristicis defined as NRR(Natural rate of rise of leakage) and used to decision making for prioritizing active leakage controlof DMAs. However, this restoration characteristic is well recognized, but researches on NRR in the water distribution system are insufficient in Korea. In this study, the estimation method of NRR was developed suitable for applicating in Korea considering of SCADA data, water infrastructure, and water usage patterns by modification of the UK's NRR method. The proposed method was applied to 9 DMAs and verified it's applicability by comparing with the other water loss performance indicators. It is expected that the proposed method can be used to support decision making for sustainable NRW(Nor-revenue water) management in the water distribution system. |
