                            PROPOSED RECONFIGURATION OF A LOT
                            216 BLACK MOUNTAIN ROAD, BLACK MOUNTAIN

       To evenly distribute wastewater throughout the irrigation area, a pressure equalisation system
        should be installed.
       Construct irrigation laterals parallel with the natural ground surface contours.
       Erect signage at the boundaries of the area in at least two places in accordance with Council
        requirements to warn people regarding the presence of wastewater pipes (e.g. “Sewage Effluent
        Pipework Installed Below – DO NOT DIG” or “Recycled Water – Avoid Contact - DO NOT DRINK”).
Detailed design of the effluent disposal systems must be carried out by an NC Registered Evaluator to
accompany the plumbing application at the building stage.

8.3.4       Maintenance and Inspection
To comply with NC requirements, the following management and inspection shall be implemented once the
effluent disposal systems are established:

       Continuous monitoring by the property owner for any signs of system failure such as septic odour,
        seepage, soil and/or plant discolouration.
       Should any signs of system failure be observed by the property owner, including the in-built HSTP
        failure alarm, the manufacturer shall be contacted immediately to arrange for the necessary repairs.
       Quarterly inspection, testing and repair (if necessary) to the HSTP and irrigation area by a Licensed
        Inspector (normally a service provided by the HSTP manufacturer).
