Laboratory Experiments on Efficiency of Foul Flush Diversion Systems

Laboratory experiments on the efficiency of foul flush diversion systems to be used in roof catchment rainwater supplies were carried out at Dundee University in 1985. Devices that collect the initial rainwater flush, and once are full act on the principle of overflow were tested: their efficiency in not allowing the suspended matter of the initial flush to enter reservoir storage was examined. The diverters used were full-scale models of three box-shaped and three pipe diverters. Assuming that (a) the first flush in a rainfall event is foul and is equal to the capacity of a diverter, and that (b) the subsequent flow is clean water, then it was proved that one of the pipe diverters is the most efficient design.
