5.8   MUSIC RAINFALL PARAMETERS

Nambour meteorological data was utilised for the MUSIC analysis. Modelling of the site was analysed for a period
of 10 years (1989 - 1998) using a 6 minute time-step period. Average potential evapo-transpiration data has been
taken from the MUSIC software package.



5.9   MUSIC TREATMENT NODE PARAMETERS

Rainwater Tanks:


Rainwater tanks with a total capacity of 20kL are to be installed within the development site. Water from the
rainwater tanks will be utilised for outdoor irrigation and wash down re-use and potentially toilet flush.

Bio-Retention System / Rain Gardens:


Details of the proposed bio-retention systems are shown in Table 16. Appendix A provides a typical detail for a
bio-retention system.
