Abstract
In this study, It is considered systematically how to increase revenue water ratio.
The various operating methods are applied to increase revenue water ratio in the Naju city, such as building block system, water pressure management. As a result of increasing revenue water ratio since 2009, revenue water ratio was improved as 83.5% in 2012, but the ratio was 64.5% in 2008. It means that annually water production of 1.3million㎥ and cost of 2.4billion won are reduced. Revenue water ratio which has been achieved high level is not easily decrease. And it makes less manpower and time investment to maintain efficient distribution network system.
In order to increase revenue water ratio, it is essential to build block system and pressure management. In addition, it is more economic to determine proper level of revenue water ratio than to determine excessive level, because amounts of investment are required to achieve the excessive level

Keywords: revenue water ratio, block system, pressure control of water pipe, operation method of pipe network, water loss
