| Abstract | ||
| Since particle accumulation in the pipes is conditioned by the usual daily flow patterns, it is assumed a velocity greater than daily peak value is needed to resuspend. The EPANET software was used to simulate the effect of six hypothetical burst flow (5, 10, 15, 20, 25, and 30) L/s in the pipe of 90 mm diameter in a part of the distribution system in Western Australia and the total number of affected pipes that expose to exceed its maximum conditioning velocity were analysed. Results showed that 15 L/s can adopting as the best flow in controlling the discoloration phenomenon when water companies maintain their distribution systems by carrying out water releases from time to time to minimise the build-up of deposits in the mains and get rid of the sediment in the pipe before it becomes serious problem. | ||
