    • An external water spray system (EWSS) is a domestic external fire sprinkler system designed to protect homes from bushfires and wildfires. While external spray systems have long been used in fire protection for buildings and facilities, EWSS refers to domestic bushfire/wildfire systems.


    Usage


    The types of systems vary greatly from a single impact sprinkler placed on a roof, systems installed during construction with sprays on all windows and doors, and small sprays damping gutters. Some are installed using copper piping and sprays while others use common PVC piping.
    Usage depends on type of risk and belief of effectiveness. Copper piping is used to withstand high temperatures that may be experienced during a fire front or for higher reliability for in ceiling installations. External PVC piping is used where failure with exposure to high radiant heat is acceptable, as at the time the system is considered have "done its job". This is a matter of personal judgment.


    Issues


    There is a lack of scientific research regarding EWSS. Other issues that may affect the effectiveness of an EWSS:

    Sprinkler performance in high wind conditions typical in a bushfire
    Home design
    High vulnerability areas. e.g. decking
    Garden beds near walls
    Window sills
    Large windows (heat radiation)
    Internal furnishings (e.g. curtains)
    Home location
    Slope
    Surrounding vegetation
    If defended by occupiers
    Preparation (if prepared for defense)
    If intended for remote (unattended) defense
    Available water supply
    Ember attack
    Fire front (radiant heat)
    Adjacent building or vegetation fire


    Types


    Roof impact sprinkler
    Gutter sprays
    Window spray / deluge
    Commercial sprays designed for EWSS are available, but most systems use commonly available irrigation sprinklers/sprays.


    Research


    External spray systems for buildings are well documented for protection from fires in adjacent buildings. However, up there is little published scientific research on scientific information pertaining to the effectiveness of EWSS under varying wildfire conditions.
