What type of development can be assessed using the Tool?

The InSite Water Tool can be applied to small-scale development sites (less than 5,000 m2) in South Australia. Note: For sites larger the 5000 m2, or very complex developments, the eWater MUSIC software or other equivalent stormwater design package can be used for stormwater design to demonstrate compliance with performance criteria for stormwater runoff quality1.

The Tool is suitable for the design of stormwater management solutions for:

  • additions
  • single dwellings
  • dual occupancies
  • townhouses
  • apartments
  • commercial, retail and light industrial developments.

Across Australia, Councils are contending with the stormwater management challenges associated with the cumulative impacts of small-scale developments within highly urbanised areas. Increasing urban density intensifies stormwater impacts of flooding, scouring downstream creeks and rivers. Increasing impervious areas overwhelm existing pipes and infrastructure, and accelerates destruction of aquatic and riparian habitat through changing the flow regimes in waterways. They also prevent infiltration of water that would otherwise help sustain deep rooted vegetation, such as trees.
