Stormwater management status quo• Why stormwater management?
• Current practice

Interventions
• Impermeable roads• Kerbs, inlets, and storm sewers• High energy outlets onto floodplanes, wetlands, and
estuaries• Channelisation of natural waterways

Effects of urbanization
• Increased run-off volumes• Increased run-off concentrations• Flooding and damage to property• Decreased natural infiltration• Lower water table• Increased temperature in natural streams• Increased pollution
