Bushfire Hazard Assessment & Management Plan v4 - 7 Triller Court, Pomona

4. Water Supply Specification
    Installed reticulated hydrant systems are to be located on roadways or access ways for all material
    change of use and reconfigured lots for fire fighting purposes as per AS 2419.1 2005 Appendix B that
    provides a minimum standard for hydrant intervals. In a Local Government Authority where a local
    water authority specifies a design and performance criteria above the requirements of AS 2419.1 2005
    Appendix B, the local water authority requirements will be adopted.

    For the installed reticulated hydrant systems the minimum water flow rate and pressure is to be 10
    L/S @ 200 Kpa as per AS 2419.1 2005 Table 2.2 (for building Class 2-9 only). In a Local Government
    Authority where a local water authority specifies a flow rate and pressure above the requirements of AS
    2419.1 2005 Table 2.2, the local water authority requirements will be adopted.

    available, operable hydrants the minimum required performance standard as per AS 2419.1 2005.
    are to be provided.
    Rationale:
    Firefighters use water as a prime extinguishing medium for structure fires. Reticulated water mains have
    hydrants placed at regular intervals to enable firefighters to connect into the reticulated system. The
    water is pressurised by pumps in the fire truck and delivered via hoses to the fire.

    Figure 1 illustrates hydrant locations on reticulated water mains.
