Repairs to overland flow structures

Overland flow water is water (including floodwater) that flows over land (outside of a watercourse or lake) after having fallen as rain or after rising to the surface naturally from underground. Overland flow structures include gully dams, ring tanks, flow-concentrating channels, and retaining walls that can redirect and take overland flow water.

Works to take overland flow water can be maintained and repaired in regulated areas without further approvals, provided:

  • the works are not altered so they store more water
  • the specifications still meet the details provided in overland flow notifications, certifications or licences.

Contact your local business centre for advice about proposed changes to existing structures or the installation of new structures. You may need approvals under the State Development Assessment Provisions or ensure that works comply with a self-assessable code before starting any work.
