Concept design

• Summary of MUSIC modelling (or alternative method or models) including:
• version of MUSIC
• meteorological data used
• map outlining catchment areas and direction of flows
• calculations and justification for choice of source node impervious percentage
• any routing used and calculations
• treatment node parameters
• any modelling parameters that are not in accordance with this document and Melbourne Water’s MUSIC Modelling Guidelines with justification for variations
• pollutant removal results
• A copy of the MUSIC model
• A report from the MUSIC Auditor tool
• Drawings of the treatment system including placements which match the model.

Functional/detail design

All of the above and the following:

• A description of the updated MUSIC model including matching:
• the inlet pond volume in MUSIC to the sediment pond volume shown on plans (from halfway up the sediment accumulation zone).
• the permanent pool volume to the proposed bathymetry (using the user defined stage-storage relationship).
• the high flow bypass configuration to the design.
• the extended detention controlled outlet configuration to the design (using the user defined stage-storage relationship).
• An inundation frequency analysis of water levels in the macrophyte zone and the 90th percentile residence time in the macrophyte zone (Report form Wetland Analysis Tool or equivalent).
