Research and Apply Methods to Calculate Water Loss Rates for Distribution Networks

The rate of water loss per hour is determined based on the pressure of the water supply pipeline, through the leakage water flow estimate table of Thu Duc WASUCO J.S.C, combined with linear interpolation formula and percentage calculation, applying calculations based on data collected from DMA Metro An Phu area, City Thu Duc. Calculation results show that the average water leakage rate of the area is 29.91%, a difference of 0.09%; the leakage of water flow is 1740.07 (m3/h), a difference of 5.45 (m3/h), equivalent to 0.31% compared to the collected data. With calculation results close to reality in the DMA Metro An Phu area, the author proposes to use this method to determine the rate of water leakage in each hour, thereby determining the amount of water lost and its owner active in the management of water supply networks for areas with similar operating characteristics.
