Abstract
Due to the fast industrial growth and unplanned urban underground
development in Korea systematic management for underground utilities
could not have been accomplished. Unsystematic underground utilities
management has resulted in difficulty of finding exact location and
the age of it, which has potential of leading it to a disastrous
situation.
Objective of this study is on the development of deterioration
estimation and management system for water lines using GIS. This
system is constructed to estimate easily water lines deterioration by
the establishment of the geographic output system on it, search
damaged objectives near surrounding area in a situation of
destruction, and offer the information by which one can take quickly
emergency. And also, it is constructed to prevent from accident
occurring under work by presenting underground utilities and states of
work.
This system has largely two parts, deterioration estimation and
efficient management of water lines. Deterioration estimation system
evaluates its safety according to water lines deterioration and
management system offers general information required for water lines
management. Deterioration estimation model selected in this study is
Numerical Weighting System developed by KOWACO (Korean Water Resources
Corporation), which estimates quantitatively pipeline deterioration
using factors such as year laid, materials, diameter, etc.
Deterioration index tables were generated for the effective
estimation, and they were applied on each water lines. DB for system
application was designed by analyzing the task of water supply control
center and deterioration estimation. This system is developed by using
ARC/INFO of ESRI Company.
