LEAKAGE RISK ASSESSMENT IN WATER DISTRIBUTION SYSTEM

Abstract

This paper presents the most recent achievements in Water leakage assessment by different methodology evaluated to determine their efficacy. Hydraulic model build and simulation model is successfully running for 24hrs.Water leakage quantity calculated by two methods that are constant leakage method and dynamic leakage method for several district metered areas(DMA).To know how the hydraulic model is behaving in perspective of disaster. This paper describes a real-time water supply system hydraulic modelling using the software Synergi Water 4.9.4. Hydraulic simulation models for water distribution networks are commonly used for operational investigations and network design. However, their full potential is frequently unrealized because, in the vast majority of cases, they were calibrated using data obtained manually from the field over a specific historical time period and, as a result, accurately reflect network operational circumstances at the time. To use a hydraulic model to enhance proactive distribution network management, it must have up-to-date element asset information and be able to access current network data to run simulations. The collecting of data from a growing number of sensors in water supply systems, as well as the automatic transfer of the data to the point of use, are the consequence of recent data transfer innovation and cost reductions. This implies engineers may have constant access to actual network data, ushering in a new era of "on-line" modelling that can be used to continuously check pressure service compliance standards and lessen the impact of network events on customers, including as leakage and mains bursts. Several water companies have adopted online modelling for their respective CGs (Control Groups) that contain numerous DMAs (District Metered Areas) and are monitoring it as it is simulated with real-time data in order to improve customer satisfaction. The approach has shifted from reactive to proactive.
