Abstract

Leakage of waterworks pipe line net cause loss of water resources, additional foundation of pressurization facilities from pressure loss and soil weakening near leaked pipe line, etc.. This makes it difficult to maintain and manage waterworks pipe line net and so cause serious economic loss. The rate of accounted water can be improved by monitoring always water pressure and flux, and so on. from isolated region, preparing positively against leakage accident and preventing leakage from occurring. Actually after isolating region, average rate of accounted water in this region went up 88.94% by continuously monitoring control of water pressure and inflow rate. It is about 9.44% higher than that of Busan metropolitan city in 2003, 79.5%.
