Changing weather patterns and increasing urbanisation have led to a realisation that conventional approaches to solving stormwater problems are not sustainable.

Traditional techniques used to address stormwater runoff often include the construction of larger interceptor drainage systems to cope with higher flow rates and run off volumes. Increasing conveyance capacity is very costly and transfers flows further downstream, creating the potential for flooding and erosion. Surface water detention ponds can sterilise valuable building land and may create a health and safety hazard.

Key features of Sustainable Drainage Systems:
. Manage stormwater runoff rates.
. Reduce adverse impacts of urbanisation.
. Protect and enhance water quality.
. Sympathetic to the natural environment and local community.
. Encourage natural groundwater recharge.

. Allow reuse of stormwater to ease load on resources.
