            The proposed treatment train has been modelled as shown in Figure 4.3 - MUSIC
            Stormwater Treatment Train. The details of the treatments are described in the following
            sections

                        4.2.1.1.       Rainwater Tanks

            The rainwater tanks collecting roof water are connected to the source nodes representing
            their drained catchments. Each of the tanks to be provided is modelled as a 5kL storage
            volume, with 2.5kL allocated for re-use (assumed to be full at beginning of the modelling)
            and the remaining portion being for attenuation purposes.
