WSUD reflects a new paradigm in the planning and design of urban environments that is ‘sensitive’ to the issues of water sustainability and environmental protection.
As defined by Wong (2006a), WSUD is focused on the synergies within and between the urban built form and landscape, and the urban water cycle, recognising that community values and aspirations play an important role in urban design decisions and water management practices. Therefore it challenges conventional urban water servicing by inter-linking the management of urban water streams (potable supply, wastewater and stormwater) with the goals of minimising and treating pollution discharges, reducing potable water use, and efficiently matching different water sources
(such as recycled water and treated stormwater) to ‘fit-for-purpose’ uses.
These aims are met through the urban design process (the planning and architectural design of urban environments) by: the provision of integrated urban water management infrastructure; reintroducing the aesthetic and intrinsic values of waterways back into the urban landscape; and promoting new forms of urban design and architecture within the built environment (Wong, 2006b).

Council adopted DCP 25 (Sustainable Water) in 2004. For full guidelines on roof stormwater and site drainage issues please refer to the DCP.
For disposal of stormwater overflows from rainwater tank storage, on-site detention, driveways and paved areas or private property generally, gravity drainage is required where possible in combination with an easement over downstream properties if necessary. Pump out systems will only be allowed for basement or ramp waters. 'Charged systems' or absorption trenches are permissible for properties sloping down from the street to the rear, so long as they adhere to concept guidelines in the Sustainable Water DCP No.25
All stormwater connections to Council systems are to be done under Council supervision following payments of fees and charges.
