Additional modelling during the construction documentation stage will help refine this
retention storage volume, regardless of the result a minimum 40 kL of retention rainwater
storage volume will be provided.
4.3. OVERALL DEVELOPED SITE MUSIC MODEL
The overall proposed preliminary stormwater design for the site has been conducted in
accordance with the Noosa Plan 2020, Part 9.4.8 Water Quality and Drainage Code. The resultant
treatment train is shown in Figure 5 below. This MUSIC (Model for Urban Stormwater
Improvement Conceptualisation) Model below only shows one (1) No. 20kL Retention rainwater
tank, where it is proposed to install two (2) No. 20kL Retention tanks.
Figure 5; MUSIC Stormwater Treatment Train and Effectiveness Model
This MUSIC model, the Proposed Preliminary Stormwater Site Layout Plan and this report shows
compliance (meets or betters the minimum design requirements) with the required
Performance Outcomes of the Stormwater Drainage Design P01 – P05, the requirements of the
Stormwater Quality and Protection of Receiving Waters P06-P09, and also Hydrology and waterway
stability PO10 – PO13 (Note: that some areas/requirements are not applicable or relevant to the
proposed works).
