                DRAINAGE CONTROL
                                                                  on your buildinigsite


                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).

                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.
