Water loss management: A case study in Korea. Water Practice & Technology

J. Y. Mun, D. G. Kim, B. J. Kang, Y. H. Park, and H. W. Ahn, 2008

A case of water loss management on a small city whose water supply is approximately 34,000 ?/day is examined. Revenue water ratio was just 55% mostly because of water loss caused by old pipes and difficulties in pipeline management in the beginning 2004. From 2005 to 2006, 50 km of pipe was replaced due to leaks, poor resultant water quality, blockage or corrosion. In all the new pipes, water meters and valves were replaced as well. This has already led to water savings, and the city plans to continue maintaining and replacing pipes as needed. Overall, through systematic management and rehabilitation/replacement of pipelines, water leakage has decreased dramatically, and the revenue water ratio has increased from 55% to 70% in just 2 years.
