1890 Effluent Disposal Review · MCU20/0022

       If the following parameter values are input into the formula:
                   t      =     22;
                   K      =     0.12 (representative)
                   I      =     0.025 (1:40);
                          =     0.2;

       an indicative setback distance (D) of less than one metre results. This is less than
       the 10 metres horizontal setback distance adopted. Further, there are no dams, and/or
       watercourses within 10 metres from the proposed effluent land application area



5      Conclusion
5.1    Soil absorption properties and site features are adequate for on-site effluent disposal
       provided the recommendations made herein are followed and/or amended by a
       licensed plumber or suitably qualified-system designer.

5.2    The homeowner should fully inform themselves about the on-site wastewater system
       on their property and its operation and maintenance. The supplier and/or installer
       of the treatment system will supply their operation and maintenance guideline.

5.3    Attached as APPENDIX B is a generic operation and maintenance guideline relevant
       to secondary and advanced secondary effluent qualities.



Yours faithfully
