Prevent flooding and blockages on your property

​Keep drains clear

Keep drains clear of litter, debris, leaves and rubbish.

Avoid planting near pipes. Roots may damage or block underground pipes.

If you are building or renovating, keep sediment and construction waste away from drains.

Our tip

Check GIS viewer first to find out where stormwater pipes are located.

To get assistance, look for a registered plumber or drainage contractor. See the Plumbers, Gasfitters and Drainlayers Board website.

Add permeable areas

If you plan to landscape or build, consider adding more permeable areas [glossary term].

Besides lawns and grassy patches, there are pavements that absorb water. Permeable pavements have a porous surface that allows stormwater to soak through. This minimises runoff going into drains.

Porous concrete and asphalt are good permeable paving for car parks, driveways and paths.

Manage water flow

Be mindful of how water flows and collects on your property. Take a note of low areas where water may pool.

Shape your driveway and other paved areas so that water flows away from your house and into a drain.

If the ground level outside your house is the same as the inside floor level you are more likely to be flooded.  Maintain a step up between the outside and inside of your house.

Do not block overland flow paths

An overland flow path is a route that rain takes to reach waterways during heavy rainfall. When blocked, it can cause flooding in your property or onto neighbouring properties.

Do not build fences, sheds and other structures that block overland flow paths. Raising the ground level around such paths may cause more flooding.

Our tip

Check GIS viewer for an indication of whether your property has an overland flow path.

You have to accept stormwater runoff that naturally flows onto your property. To know more, read the Stormwater Bylaw.

To know more about overland flow paths and how to manage them, see Stormwater forms and guides.
