In order to study how information and technology can be used to improve water management, smart grid technologies were introduced into the water industry. This paper describes a project to integrate GIS, SCADA and online hydraulic model to assist water engineers in assessing the water distribution system. The integrated system simulates the flow and concentration of chemical contaminants online in municipality's water distribution system. The integrated system is a powerful tool for routine planning and emergency response and also for remote leakage detection and prediction of pipe burst. The capabilities of the integrated system can greatly assist in the decision making processes for network asset inventory, rehabilitation requirements, and financial planning.

This paper describes a project to integrate EPANET, Giris and SCADA to assist water engineers in assessing the water distribution system in city S. The integrated system simulates the flow and concentration of chemical contaminants in municipality's water distribution system. The integrated model is a powerful tool for routine planning and emergency response. The capabilities of the model can greatly assist in the decision making processes for network asset inventory, rehabilitation requirements, and financial planning. The system was tested using the S City database composed of approximately 13219 junctions and 14832 pipes whose diameter not less than 300 mm.

Theory Of Evidence

This paper presents a decision support methodology aimed at assisting Water Distribution System (WDS) operators in the timely location of pipe bursts. This will enable them to react more systematically and promptly. The information gathered from various data sources to help locate where a pipe burst might have occurred is frequently conflicting and imperfect. The methodology developed in this paper deals effectively with such information sources. The raw data collected in the field is first processed by means of several models, namely the pipe burst prediction model, the hydraulic model and the customer contacts model. The Dempster–Shafer Theory of Evidence is then used to combine the outputs of these models with the aim of increasing the certainty of determining the location of a pipe burst within a WDS. This new methodology has been applied to several semi-real case studies. The results obtained demonstrate that the method shows potential for locating the area of a pipe burst by capturing the varying credibility of the individual models based on their historical performance.

Abstract Understanding water distribution system hydraulic performance is crucial for a water supply system management. A case study was conducted evaluating the hydraulic performance of water distribution system of Tulu Bolo town. The hydraulic model of water distribution network was developed using GIS integrated with WaterGEMS hydraulic model. The implementation of the integrated system verified that water to regulate the pressure and velocity in order to sustain. According to the analysis, about 92.6% of nodes have optimized pressure ranged between 15m to 70m and about 1.27% is under permissible pressure. Model calibration was performed by comparing simulated data with field data, the result of pressure calibration has a linear correlation coefficient of 0.93 and the hydraulic model in WaterGEMS was calibrated and optimized with a field data.
