4.8       FLOWS MIGITATED

The outflow from the storage system determined utilising the XP-SWMM software is shown below for a range of
storm events. The system was analysed as a single 40m2 tank with a maximum depth of 1.5m. The outlet from
the analysed tank consists of two staged outlets:


      •    2 x 1500 pipes at the invert of the tank (110 - 110 L/sec Q100 flow, 2.59m/s velocity)
      •    2 x 1500 pipes at 0.7m above the invert of the tank (70 - 80 L/sec Q100 flow, 1.79m/s velocity)
