Abstract

In this study, the risk of red water and turbid water occurrence was analyzed by classifying it into detachment risk and deposition risk. First, risk factors for red water and turbid water were determined, and hydraulic analysis was conducted considering seasonal water consumption. The applied area was Cheongju City, and the risk analysis was conducted across 13 areas, and the areas with high deposition risk and high detachment risk were selected. The high risk of both detachment and deposition can be judged as an area with a very high probability of causing water quality problems. The areas with the highest deposition risk and detachment risk are the old towns of Nae deok1-dong and Yul1yang-dong, which are the oldest areas in Cheongju City with an age of more than 30 service years of pipe installation. By analyzing the risk of deposition and detachment, it will be possible to strengthen the maintenance function of the water supply network to provide the safe water to citizens and increase their confidence for tap water.

본 연구에서는 박리위험도와 퇴적위험도로 분류하여 적수와 탁수발생 위험도를 분석하였다. 먼저, 적수 및 탁수를 발생시키는 위험 인자들을 도출 하였고 계절별 수도사용량을 고려하여 수리해석을 진행하였다. 적용 지역은 청주시로 13개 동에 걸쳐서 위험도 분석을 진행하였고 퇴적위험도가 높은 지역과 박리위험도가 높은 지역을 선정할 수 있었다. 박리와 퇴적위험도가 모두 높다는 것은 수질문제를 일으킬 가능성이 매우 높은 지역으로 판단할 수 있다. 퇴적위험도와 박리위험도가 가장 높은 지역은 내덕1동과 율량동 구시가지로 경과년수는 30년 이상으로 청주시에서 가장 오래된 지역 이다. 퇴직위험도와 박리위험도 분석을 통해 상수관망의 유지관리 기능을 강화하여 시민들에게 안전한 물 공급을 통해 수돗물에 대한 신뢰도를 높일 수 있을 것이다.
