Abstract/Description: Due to the continuous need to improve water supply sources, water operators are looking towards ways to conserve water and protect water quality through leakage protection. Currently computer generated models have been used to try to identify leakage areas and develop a relationship between leakage and pressure variations in water systems. The method of the leakage prediction has used both transient analysis and inverse transient analysis to determine the relationship between leakage and pressure variations. Currently there has been limited success in both these methods. The experiment expressed in this research will explore the accuracy of the WaterCAD software to develop a relationship between pressure variations and leakage quantities and leakage locations. Engineers and owners of water systems use the WaterCAD software to develop models of both proposed and existing water distribution systems. If these same models could be calibrated using post-condition pressure values and using system parameters (roughness coefficients, etc.) pressure differences in the system which do not match the calibrated computer generated model could be identified thereby indicating a leakage and possibly suggest a location for the leakage. Using a previous transient experiment for both reference and calibration, the effects of leakage on pressure variations within a distribution system were explored. The results found within this experiment suggest that there is a relationship between pressure variations and leakage quantities. The location of leakage areas also affects the pressures within the distribution system. By examining the results of this experiment, both engineers and water operators can learn how leakage affects pressure within a water system and become more aware of these symptoms for leakage prevention.
