            DRAINAGE CONTROL
                                                                   on your building site


            Soil erosion in unlined diversion drains can be controlled with the use of check dams constructed from
            sand or gravel filled bags. Space the check dams so the crest of the down-slope dam is level with the base
            of the up-slope dam (refer Figure 5.3).




            Check dams




           The early connection of roof water to the stormwater
           system will reduce site wetness and the generation of
           on-site mud. Temporary or permanent downpipes
           should be installed prior to frame inspection and as
           soon as practicable after the roof is laid.

           This practice has been shown to reduce downtime
           following storm events and decrease the average
            building construction time.
