Year-round rainfall

Tanks refill across the seasons, so indoor use for toilets and laundry delivers a steady saving.

Clay base

Reactive clay across much of Canberra needs a compacted pad or slab under the tank.

Frost

Exposed pipes, pumps and first-flush devices can freeze; lagging and sensible placement matter.

Planning rules

ACT rules on tank size, height and setbacks apply, and heritage precincts in the inner suburbs have extra requirements.

FAQ

Frequently asked questions

How much does water tanks & stormwater cost in Canberra?+
Water Tanks & Stormwater in Canberra: $2,790–$13,950. Midpoint estimate $8,370. Modelled estimate; verified submission count unavailable. These figures are not calculated from consumer submissions.
Is a rainwater tank worth it in Canberra?+
More than in most Australian cities. Rain falls through the year rather than in one season, so a plumbed tank keeps supplying toilets and laundry for months at a time, and ACT water is not cheap. A garden-only tank still helps through the dry spells of summer. Size it to your roof and plumb it in; that is the version that pays back.
What size tank suits a Canberra home?+
Match the roof area. With around 600mm a year across a standard family roof, a 5,000 to 10,000 litre tank fills regularly and supports toilets and laundry through most of the year. Bigger is not better if the roof cannot fill it; ask the installer to size it from your roof area and intended use.
How do I stop the tank freezing?+
Tanks themselves rarely freeze, but pumps, exposed pipes and first-flush diverters can in a hard Canberra frost. Place the pump in a housing or a sheltered spot, lag exposed pipework, and drain first-flush devices in winter or use a frost-tolerant model. A local installer will know the tricks.
Do I need approval for a tank in the ACT?+
