                                              Figure 4.4 – Typical Tank node configuration

            Each tank is to be fitted with a first flush diverter to prevent potential sediments from
            entering the tanks. This is modelled by assuming the first 25L of rainfall falling over the roof
            area is diverted to the first flush diverter and discharged to irrigate vegetated areas on site,
            equating to a 0.12mm increase to the rainfall threshold on the upstream roof source node.

            The tanks will be plumbed for internal and external reuse which has been modelled in
            accordance with the Water by Design MUSIC Modelling guidelines. The reuse demands
            have been determined as follows:

                    -   Internal Reuse

                           o     All homes are assumed to be fitted with full water saving devices,

                                      ▪     26L/Person/day for laundry

                                      ▪     21L/Person/day for toilets

                           o     ½ Pod C roof run-off:

                                      ▪     2x2 bed = 3.2 persons

                                      ▪     3.2 * 47L = 150.4L/day
