Storage varies with different configurations of controls and Stormwater Controls (SWC). InfoDrainage will look at two extreme cases to provide an estimate of the range of storage required for the site. This estimate may be used as a starting point for detailed design but it must never be used as a final design as the variables it assumes are significant. In certain circumstances, it is also possible to achieve a final design outside the range shown.
