# Stormwater 1.1 Stormwater Treatment

# Applies to

All development, including residential and non-residential development

# Objective

To minimise negative environmental impacts of stormwater runoff and maximise onsite re-use of stormwater

# Summary

Points are awarded when a STORM rating of at least 100% or equivalent modelling results (e.g. MUSIC *) has been achieved.

*Consult with the relevant council to determine which tool is most appropriate for your development.

# Documentation & evidence required

  • Copy of STORM or MUSIC report
  • Drawings indicating catchment areas, slope of paved surfaces to treatment systems, construction details of proposed treatment systems, e.g. raingardens
  • Landscape drawings indicating appropriate planting within and adjacent to treatment systems

# Other Considerations

Applicants are encouraged to consider additional Stormwater Management strategies not currently included within the tool scoring, for example:

  • Installing gross pollutant traps where hardstand paving drains to SW system
  • Installing pervious paving where appropriate
  • For industrial developments - contain polluting activities within the canopy line or within a bunded area
