Why Concrete Water Tanks Are the Right Choice for Perth Properties
Concrete water tanks offer clear advantages for Perth's climate. Perth endures some of Australia's hottest summers, with temperatures frequently pushing past 40°C across suburbs like Armadale, Serpentine, and Kelmscott. Concrete's thermal mass can help keep stored water cooler than poly or steel alternatives, which may reduce algae growth. Concrete tanks also do not require an internal liner, do not corrode, and can outlast poly and steel tanks by many years. For properties across the Perth metropolitan region, including the Hills districts and southern rural corridors, a concrete tank may prove the most cost-effective choice over its lifetime.
Are There Rebates for Water Tanks in Perth?
Eligible WA residents may be able to access financial support through the Water Corporation's regional rainwater tank rebate programme. The Water Corporation currently runs a regional rainwater tank rebate for eligible towns in the South West and Great Southern regions, open from 1 September 2025 to 31 May 2026, covering new tank purchases, the plumbing-in of existing tanks, and tank replacements. Perth metro properties are not currently part of the regional rebate, but eligibility criteria and offers can change each season.

Which Water Tank Material Suits Perth Homes?
Concrete, poly, and steel each have real strengths, but Perth's long dry summers, high UV intensity, and sandy soils often tip the balance toward concrete for large-capacity and permanent installations.
Concrete tanks are built for longevity. They naturally insulate stored water against Perth's heat, can be installed above or below ground, are unaffected by soil movement across sandy flats and clay-heavy lots, and require no liner. For properties in the Hills or rural blocks between Serpentine and Mundijong, a concrete tank can be constructed on-site to match your exact footprint.
Poly tanks are lightweight and carry a lower upfront cost, suiting smaller suburban blocks with tight access. However, poly tanks are not recommended for prolonged exposure to temperatures above 40 degrees, which is relevant across Perth's inland suburbs and the Armadale corridor during summer.
Steel tanks offer high heat tolerance for large rural storage but may require a liner and periodic maintenance, particularly on coastal or limestone-based properties.
For households needing large-volume, long-service-life storage, concrete remains the preferred choice across much of Perth and the South West.
What Size Water Tank Do I Need for a Perth Home?
Tank sizing depends on household size, intended use, roof catchment area, and how many days of independent supply you want to hold.
Perth receives most rainfall between May and September, with dry summers stretching four to five months. A useful starting point is to estimate daily usage and multiply by the dry days you want to cover. Allow roughly 80 to 150 litres per person per day when rainwater is used indoors.
As a rough guide: family homes wanting rainwater for indoor and outdoor use typically benefit from a 10,000 to 22,500 litre tank, while rural and semi-rural properties around Serpentine-Jarrahdale and Byford, or hobby farms running livestock, often require tanks well above 27,000 litres.
Armadale Concrete Tank Co. constructs tanks from 27,000 litres up to 1,000,000 litres, suiting large residential blocks through to commercial and agricultural sites across WA. Roof area also matters: roughly 1mm of rain on 1 square metre of roof yields approximately 1 litre of water. Request a free site visit for sizing advice matched to your property.

Most Perth homes suit 27,000L to 90,000L. An on-site consultation helps confirm the ideal size for your property.
How Long Do Concrete Water Tanks Last?
Concrete tanks outlast poly and steel alternatives. High-grade construction resists corrosion and requires no liner, supporting a much longer usable lifespan.

Yes. Properly manufactured concrete tanks are safe for drinking water and help regulate temperature and reduce algae growth.
Do You Offer Water Tank Maintenance and Cleaning in Perth?
Yes. Armadale Concrete Tank Co. offers water tank maintenance and repair services, including crack repair, outlet repairs, and tank cleaning.
How Long Do Concrete Water Tanks Last Compared to Other Materials?
Concrete tanks are engineered for strength, require no liner, and keep stored water cooler. With proper construction and routine maintenance, a well-built concrete tank may remain serviceable for several decades.
Can Concrete Water Tanks Be Installed Underground in Perth?
Yes. Underground installation is popular on suburban and rural lots where space is limited or where the tank needs to remain visually unobtrusive.
Do I Need Council Approval to Install a Water Tank in Perth?
Approval requirements vary depending on tank size, placement, and local council rules. Full support for compliance, permits, and engineering approvals can be provided as part of the construction process. Confirm requirements with your local City or Shire before installation begins.
What Maintenance Does a Concrete Water Tank Require?
Concrete tanks are low maintenance, but periodic checks protect water quality and extend service life. Inspecting your tank every six months is recommended, as Perth's hot summers and winter rains cause expansion and contraction that can lead to small cracks. Armadale Concrete Tank Co. offers water tank maintenance and repair services and professional tank cleaning to keep your system in reliable condition.
