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).

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
directing stormwater towards
the site's entry/exit point
(refer Figure 5.2).
