Attachment I - Updated Engineering Report & SWMP

              The efficiency of the proposed treatment train has been identified by
              the Model for Urban Stormwater Improvement Conceptualisation
              (MUSIC) developed by Monash University.

              A conceptual layout of the treatment train for the site, as input to the
              MUSIC Model, is shown in Figure 6.3.




                         Figure 6.3: MUSIC Model Layout

              The location and details of the water quality treatment device is
              shown on the preliminary engineering drawings contained in
              appendix B.



              6.3.2 MUSIC Model Input

              The Rainfall Runoff Parameters for the source catchments have been
              taken from Water By Design’s – MUSIC Modelling Guidelines,
              Version 1.0 2010 and are shown in Table 6.3.2.
