Drainage System
A drainage system is a system of gully inlets, pipes, overland flow paths, open channels, culverts and detention basins used to convey stormwater runoff to its receiving waters. In urban areas stormwater runoff volumes are typically greater than they were prior to urbanisation because of increased impervious areas within catchments. Drainage systems are designed to reduce the risk of council, community and private assets being damaged by localised flooding as a result of these increased runoff volumes.
