Unblock gutters and drains

Landowners are responsible for keeping gutters and drains clear of debris.

  • Keep your drains clear of litter, debris, leaves and other objects.
  • Check that your roof gutters connect to your downpipes and the water flows out to drains.
  • Avoid planting trees close to pipes. Roots damage or block underground pipes.
  • Contact a plumber or a drainage contractor for private drainage problems. See the Plumbers, Gasfitters and Drainlayers Board website.

Do not block overland flow paths

An overland flow path is a course that surfacewater takes as it flows naturally over land. It is a flood hazard area.

If overland flow paths become blocked, it could result in flooding in your property or your neighbour's property.

Be flood wise - build with nature not against it

Manage flooding on your property by following these guidelines: 

  • Be mindful of how water flows and collects especially when building homes, garages or sheds.
  • Reduce the amount of paved areas on your property. Concrete and asphalt cannot absorb water and can increase flood risk.
  • Keep areas that absorb water. Use permeable paving on your driveways and paths. 
  • Ensure that fences, sheds, permanent structures and plants do not block overland flow paths.
  • Avoid raising the ground level around an identified flow path.
  • Shape your driveway and other paved areas so that water flows away from your house and into a drain.
  • Do not divert flood waters from your property.
  • Build living areas, such as the lounge, kitchen and bedrooms, above the flood level.
  • Install water-resistant doors.
  • Dispose construction waste properly and prevent mud and sediment from ending up in drains.

You are legally required to accept stormwater runoff that naturally flows onto your property. 

Do not obstruct or divert flood waters as this may affect other properties. This applies to all properties regardless of location.
