Flooding from a neighbour's property

You are responsible for flooding and blockages on your property.

If you're experiencing regular, minor flooding due to a problem on your neighbour's property, talk to your neighbour about how to resolve the issue.

Flooding from your neighbour's property can be caused by:

• blockages (including fences blocking overland flow paths)
• broken pipes or guttering
• construction
• heavy rain
• flooded waterways
• landscaping
• damage to property.
