3.3.5 MUSIC Treatment Node Parameters

Bioretention Basin

Figure 3-2 shows the parameters used for the bioretention basin node. The basin has been
sized to fit within the available space at the southeast corner of the site, resulting in a filter
area of 210m². It features an extended detention depth of 300mm and has no saturated zone.
This basin is to be constructed as a part of Stage 1 and is design to treat catchment from the
whole site.

Note: *Healthy Waterways recommends using MUSIC version 6 to ensure compliance with stormwater pollutant load reduction
objectives, with the following parameters adopted when modelling bioretention filter media:
• Minimum 30 mg/kg Orthophosphate (OP)
• Minimum 400 mg/kg Total Nitrogen (TN)
