The study was aimed to extract the improvement measures for the problem on GIS application GIS for water supply and sewerage pipeline facility management in the Jechon city. For this, it performed of analysis of their working and modeling with other relational contents of the water and sewer facility management. As the results, the implementation of water and sewer facility management system by use of GIS has to applying development through relational analysis not only pipeline facility and leaking water protection, pipeline network analysis but also digital topography, drawing data, water user's information.

Sewerage is the system that improves the quality of human life and prevents many disasters such as floods. However the investigators in Korea only have been concerned about the sewer system, so the sewage treatment plant stays in the basic level like mapping. For example, only one attribute can be recognized in the linear object. Because of this limitation, it makes difficult to manage the linear attribute regarding to the sewage pipe plan. And it is impossible to control a partial (point type, line type) attribute changes of the linear object. We will therefore present the applicable method for the attribute changes of the linear object like the sewage pipe plans. For this reason, this paper is designed on the basis of Dynamic Segmentation(DS). DS has the advantage of giving the attribute value to the exact place in the linear object. As a result of using DS, the variety environment changes around the sewage pipes are applied to the building sewerage data. This also makes it possible to get a precise estimation for the maximum dirty water amount.
