Protecting your Property from Flooding

Springs and runoff

Landowners are responsible for ensuring that their home and property are landscaped and designed to avoid property damage from springs and runoff. Please view the Stormwater: Protecting your house and property from springs and runoff pamphlet (PDF 423KB) (Word 28KB) for advice on how to ensure the safety of your property and neighbouring properties. It is important that you allow water to flow naturally from your neighbour’s property, and that it continues to flow to neighbouring properties without concentrating.

Please ensure that your gutters and down pipes are clear and without leaks. During a moderate rainfall event it is a good idea to check that your down pipes and gutters are functioning as they should.

Responsibility for blockages in stormwater flow on your property

You are responsible for blockages in the stormwater drainage on your property. If you live in a newer suburb you are probably connected to the municipal stormwater network at a tie point. The property owner is responsible for stormwater blockages up stream of the tie and that Roads ACT is responsible for blockages below the tie point.

If you are experiencing a stormwater drainage blockage you need to contact a plumber to investigate and fix the problem. If the plumber finds that the blockage is outside your property the plumber must expose the tie point and arrange for ActewAGL to examine the tie point to determine where the blockage is located. If the blockage is the responsibility of Roads ACT you will be reimbursed for the expense of having the tie exposed.

Cut off drains

Cut off drains filled with debris, are a potential flood and pollution hazard. Please ensure that any cut off drain behind your house is clear from debris.

Riverine flooding

Some houses in Canberra may be at risk of riverine flooding during or after a major storm event (a 1% EAP event, formerly known as a 1 in 100 year event). Riverine flooding happens when water overflows the banks of rivers and other waterway channels linked to river systems.
