Application depth — design: Stormwater drainage

Stormwater systems collect and convey rainfall runoff to safe discharge points. Design is driven by catchment hydrology, allowable surcharge, and structural loading on buried conduits.

Size for the design storm hydrograph and freeboard policy of the authority. Select stiffness class for cover depth and traffic. Consider access for cleaning and grit chambers where sediments are expected.

Urban flash rainfall in Saudi cities creates short, intense peaks. Conveyance must handle debris, occasional standing water, and aggressive soils without rapid corrosion.
