    DRAINAGE CONTROL
                                                       on your building site



    Where practicable, or where stormwater run-off from more than 0.5 ha feeds into the work site, divert
    up-slope water around the soil disturbance. Stormwater can be diverted with the use of small catch drains
    or perimeter banks (refer Fact Sheet 3). Line all high flow velocity drains with turf or a geotextile fabric to
    avoid unnecessary soil erosion
    (refer Figure 5.1).
                                                                                            3cOmm (n.r) depta
    Diverted stormwater should
    be discharged onto stable
    areas and should not be
    diverted into neighbouring
    properties, unless written
    permission is obtained from
    the land owner(s). Avoid
