                               Table 8.2 Treatment Train Effectiveness



                     Inspection of Table 8.2 shows that the target pollutant load reductions will be
                     achieved for the developed site.




                     9.0 SYSTEM MAINTENANCE

                     RIPs/RICs, bioretention basins and the rainwater harvesting tank will be
                     subject to routine inspection and maintenance by the hotel’s maintenance
                     team and such maintenance is critical to their ongoing function.

                     Failure to carry out such maintenance could result in system failures,
                     environmental harm and surcharge of infiltration pits and culverts.

                     A recommended maintenance schedule for elements of the water quality
                     treatment and train and infiltration devices appears at Appendix F.
