Efficient Management, Benefits to Citizens

World’s Highest Revenue Water Ratio

The Seoul Metropolitan Government has reduced the water leak and achieved the same revenue water ratio as that of advanced countries by continuously introducing advanced water leak detection equipment and replacing old water pipes. As of the end of 2017, the revenue water rate is 95.7%, a 23.7% increase compared to 2000 (72%).

  • Revenue Water Ratios in Major Cities around the World(2016): New York, U.S. – 85.8%, Tokyo, Japan – 96.0%, Osaka, Japan – 92.2%
  • Average Revenue Water Ratio in Seven Metropolitan Cities in Korea (20 17): Incheon 89.8%, Busan 92.5%, Daegu 92.3%, Gwangju 86.7%, Daeje on 93.6%, Ulsan 88.5%

Revenue Water Ratio

This is the ratio of the amount of water generating revenues to the total amount of water produced in purification plants. If the ratio is high, it means that the loss from tap water leaks, etc., is small; thus, production volume can be reduced, which can lower the direct costs such as cost of purchasing raw water, chemicals, and power. This in turn means high efficiency of waterworks management, with the cost burden on citizens lowered accordingly (Example : 0.7% rise in the ratio (94.4% in 2013 → 95.1% in 2014) leading to budget saving of KRW 5 billion).


Efforts for Management Improvement, such as Organizational Restructuring

Since the launch of the Office of Waterworks, the number of employees, which peaked at 4,300, has been trimmed to the current 2,200. The Office of Waterworks computerized and automated various processes such as billing and adopted a new waterworks management system (GIS) and a waterworks customer inquiry satisfaction system (UMS). Through efficient management and system improvement, the Office of Waterworks has now become a more streamlined but stronger organization.
