     Table 5.7:   Water Quality Treatment Bioretention Node

To assist with the removal of the gross pollutants, it is proposed that Enviropod baskets be
installed in all stormwater gullies and inlets. The treatment node for these baskets has been
provided by SPEL.

Refer to Appendix F for the SPEL Enviropod Operations and Maintenance Manual.

The rainwater tank treatment node parameters used in the MUSIC model are shown in the
table below.
