The parameters used as the MUSIC Rainfall-Runoff Parameters are shown below in Table 5.4, and
were derived from Table 3.7 of the MUSIC Modelling Guidelines prepared by Water by Design
(2010).

Treatment parameters for the in-ground proprietary systems have been provided by the
manufacturer. Refer to Appendix F for the Stormwater360 Operations and Maintenance
Manual.

    Alternative In-Ground Proprietary System
The proposed in-ground proprietary system documented within this report is the
Stormwater360 Stormfilter cartridge system. At the time of preparing this report the
Stormwater360 Stormfilter system was the only system that is approved for use by Noosa
Council. However discussions with council have indicated that an alternative product may be
used if the alternative product does become approved for use. Based on these discussions it is
assumed that subject to their approval, council may accept a change in the proprietary
product used.
