                 The treatment train includes the following stormwater quality measures (refer Figure
                 3.2):
                      All flows from the site will be directed to field inlet pits containing gross
                       pollutant traps/filter bags (EnviroPod 200 or similar);
                      Flows from all catchments, will discharge to the end of line underground
                       stormwater detention/filtration system (ZPG Stormfilter or similar) through a
                       piped network before discharging to the external stormwater system.
                 Preliminary assessment has indicated that water quality treatment utilising the
                 filtration devices can be provided in one location on the site (refer to drawing no. 205-
                 002-C10.01 in Appendix A) with further consideration given to appropriate final
                 locations to be undertaken at detailed design stage.
                 Specific aspects of the treatment train are discussed in further detail in the sections
                 below.


        3.5.1 Stormwater Detention with Filtration

                 Stormwater from all site catchments (refer to drawing no. 205-002-C13.01 in
                 Appendix A) is proposed to be treated by a Stormwater360 detention system (or
                 approved equivalent) with a 4 cartridge ZPG Stormfilter system (Stormfilter
                 requirements determined in accordance with Stormwater360 product information -
                 refer product information provided by Stormwater 360 in Appendix B).
                 Maintenance frequency of the system is determined by the pollutant loading and in
                 this case, the system is expected to require annual maintenance.
                 Access will need to be provided for the maintenance and cleaning of the stormwater
                 filters due to their location within the product. Refer to product brochures in Appendix
