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 assuming the
caretaker facility would share similar characteristics to a 1 bedroom detached dwelling as follows:

     -    Internal Reuse

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

                          ▪    21L/Person/day for toilets

               o    1-bedroom detached dwelling:

                          ▪    1.6 persons per dwelling

                          ▪    1.6 * 21L = 33.6L/day/unit


               4.2.1.2. Bioretention Areas
A 5m² bioretention areas is to be provided within the property to capture and treat surface run-off
from the driveways as well as overflows from attenuation tanks. The bioretention areas are
modelled in accordance with the Water by Design MUSIC Guidelines 2018 with the node
configuration for one of the areas shown below in Figure 4.5 – Bioretention Node details.

Table 4.2 – Indicative Bioretention Area Plantings below (based on the Brisbane City Council Water
Sensitive Urban Design Engineering Guidelines) presents a sample of suitable plants that shall be
used to ensure the garden delivers effective nutrient removal in the bioretention areas.
