            The tanks will be plumbed for internal 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     3-bedroom townhouses:

                                           2.3 persons per unit

                                           2.3 * 47L = 108.1L/day/unit

            4.2.1.1. Pit Inserts

            The grated inlet pits in the driveway are to be fitted with Ocean Protect Ocean Guard Litter
            baskets (or approved equivalent). The inserts are modelled using generic treatment nodes,
            with a high flow bypass of 20L/s per insert and concentration-based capture efficiency set
            in accordance with the manufacturers specifications shown below in Figure 4.5 to Figure
            4.8. Refer to Appendix B Ocean Protect Ocean Guard Litter Basket for further details on
            the devices.
