Decision of water quality measurement locations for the identification of water quality problems under emergency link pipe operation

Abstract

This study suggests a methodology for the decision of water quality measurement locations in order to identify water quality problems within a pipe network system under abnormal conditions. A water supply system conversion due to the occurrence of tank or pump problems between water supply zones was set as a possible abnormal scenario and the water flow direction sensitivity of the pipeline was quantified to estimate the water quality monitoring priority. The proposed methodology was applied to a new city, A, in South Korea, and the results are analyzed in detail and presented. The proposed methodology can be used as a method to select water quality monitoring points when establishing an operation plan for emergency link pipes. It is also expected that it can be applied in the evaluation of the adequacy of the previously established emergency link pipe operation plan.
