Southern Cross® Water Tanks
Australians require water tanks for a wide variety of reasons, from people in the country who need rainwater tanks to ensure reliable water supply for their home, to those in the suburbs installing slimline tanks in the limited space on their properties to water their garden without using mains water supply.
In many commercial and industrial sectors too, water tanks are essential, fulfilling needs like fire protection, water for air conditioning, process water for mine sites, and much more.
While for many backyards around Australia, small plastic tanks like a slimline water tank or underground water tank, or even a larger above ground water tank like poly water tanks will be enough to meet their needs, for many it will not.
This is because you will find that with every litre more water storage you require than poly tanks can hold in one single tank, the more affordable it becomes to buy a steel water tank. Poly rainwater tanks also tend to be much less effective at maintaining their integrity in a fire front, something many rural Australians see as a requirement.
So if you’re in the market for a steel rainwater tank, be it for a domestic setting or a commercial one, you’ve come to the right place, as Southern Cross Water has a water tank that is right for you.
Southern Cross TL range of water tanks are liner tanks designed for the rigors of rural living. Made from Australian BlueScope steel and fitted with a heavy duty one piece food grade tank liner, this is a rainwater tank built for rural Australia.
The TL range is available with an open top, flat roof or conical roof, giving you greater control over your water storage options. These rainwater tanks, designed for potable rainwater storage and non potable water storage are available in a range of sizes, from 26kL up to 600kL.


All Southern Cross liner tanks are made from minimum 1mm galvanised steel sheets, and can be constructed on concrete, compacted gravel, mould ring or ring beam foundations.
These panel tanks, including sheets, ladders and any accessories are completely pre-fabricated for simplified transport and installation.
Southern Cross Water’s Squatter Tanks area a heavily modifiable range of water storage solutions, constructed from galvanised steel, with a bolt together “stripseal” design.
The Southern Cross Squatter Tank was the first circular bolted steel water tank introduced to the Australian market, and has been being produced since the 1960’s. Many of these first generation squatter tanks are still in operation and holding water to this day.
These rugged all-conditions water storage tanks are available in capacities ranging from 9 kilolitres all the way up to 3040 kilolitres in a range of heights and diameters.


Note: kilolitres shown are gross capacities. Where a usable capacity is specified, allowance must be made for air gap and pipework positioning
These bolt together water storage tanks are fully pre-fabricated for easy transportation and installation by our highly experienced water tank installation teams.
Squatter Tanks are available with a range of paint finishes and external coatings for both aesthetic purposes and corrosion resistance, and can be installed with an open top, flat roof or conical roof. Squatter Tanks can be constructed on concrete, compacted gravel, mould ring or ring beam foundations.
The Southern Cross YT Series Water Tanks are fit for purpose in a wide variety of industries and applications, with significant advantages over conventional concrete and welded steel tanks.
These steel bolted panel tanks are installed from the roof down, using specialised hydraulic erection equipment, removing the need to work at heights, and eliminating requirements for on-site rigging, welding, cutting or coating.
The standard size range of YT Series water tanks ranges from 12 kilolitres up to 1900 kilolitres, with storage tanks outside this range available on request.


Note: tanks outside this size range available on request. All tank sizes above listed in m³ or -000 litre
These water tanks are manufactured with an impressive minimum 2mm thick galvanised steel sheets, and can easily be retrofitted with additional panels for increased capacity at a later date.
These tanks come with coatings and liners for specific applications or installation environments, and are designed and
certified for applications including high wind and cyclonic locations as well as specific seismic conditions.
Don’t have the space for a round water tank, or need water storage for a high rise building or an underground tank in a basement system? Then a GRP Series tank – or glass reinforced plastic tank – might be the tank for you.
These square water storage tanks are designed for safe, reliable storage of clean water for building services, and potable water applications. The chemically inert construction material makes these tanks suitable for drinking water, process water or fire protection.

Some people are satisfied with the standard galvanised steel finish on their water tanks, however if you’re looking for something that fits the aesthetic of your water tank location, or is more eye catching than regular steel water tanks, Southern Cross Water Tanks are available in a range of colours sure to meet your needs.

As well as custom paint finishes, Southern Cross Water tanks can also have external coatings added to increase the design life, and additional corrosion resistance, based on your location and the water tank environment.
Water tank prices rely on a variety of factors including the current steel prices, the location of the installation site, and any accessories that may need to be installed on the water tank.
All Southern Cross Steel Water Tanks are manufactured in Murarrie, Queensland which means prices may vary from state to state due to freight costs, and installer arrangements.
Your choice for the foundation of your tank, with concrete, crushed gravel, mould ring or ring beam options, will also affect the price of your water tank.
For rural liner tanks intended for domestic rainwater collection, additional costs may include utilising a qualified plumber to hook the tank up to your rainwater harvesting system and then your rainwater tank back up to your home – and potentially disconnecting your household water from mains water.
If a water pump is required to provide water supply to the home, you may need to employ an electrician to run power down to the rainwater tank and pump for ease of installation.

“It was definitely a career highlight to be able to respond quickly and effectively to meet the needs of our client on this project.
The client had just experienced the catastrophic structural failure of one of the two 2,700,000 litre chiller tanks built on this site by another tank supplier, and we were called in to supply replacement tanks at short notice – tanks which could be relied upon to meet the structural demands of the application.
It was testament to the skill and experience of the entire Southern Cross Water team that we achieved the design, manufacture and construction of the replacement tanks on a very tight schedule.
The memory of the catastrophic failure of the original tank will always remain a timely reminder to everyone involved in the procurement of storage tanks that they must be sure to strike the right balance between price and quality.”
