Have a look through our photo galleries of recent installations and get an idea of what's possible. We supply and install everything from small 720L poly courtyard tanks to large 230,000L steel liner tanks suitable for big rural blocks, so can certainly cover your needs. Most people living in the metro area have limited space and go for something up to 5000L in size, which would be around 1800mm diameter.

You'll pay a similar price for polyethylene ('poly') and steel tanks in a round format, but more care has to be taken with the base on a steel tank to stop it flexing or twisting, so it will cost more to install. If colour's important to you, there's a limited choice in steel - but many people choose the traditional galvanised finish.

A squater version of this standard size available from all manufacturers, and ideal where the inflow is relatively low as on the side of the shed behind.

This rainwater tank is filled by a conventional 'dry' pipe off some 30m of gutters that we installed on an existing shed. It is connected by 70m of underground 'balance' pipe to a second tank so that both rise and fall together. A DAB Euroinox 40/80 surface pump is installed to supply the retic system.

This 22,000L tank with 3450mm diameter and height of 2400mm is around the largest that can be ordered. Coupled to 3 adjacent large slimlines it harvests water through a 'wet' system from the entire house roof and provides water to the whole house. We like how the concrete tank pad is curved around the tank to minimise the area lost to the garden.

The owners wished to collect more rainwater for their home and garden. These new tanks were added in a 2-phase job, where a new underground wet system and connection back to an existing tank and pump was laid before later concreting of this corner followed by connection of the tanks to the prelay. Installation in two or more phases is not unusual

The owner of an older house had downpipes simply draining out onto the ground. Adding a large patio and some paving required a solution to dispose of the water, while the tank also provides a good supply to irrigate part of the garden through a hose. This low profile tank could be moved into place underneath the patio

The perfect classic tank! Custom diameter Aquaplate tank to fit onto an existing limestone plinth and with matching galvanised pipework, this looks the part attached to an old heritage-listed house

This a good sized tank to supply a family home where there's no mains supply. The roof area of the home has to be maximised, and will fill the tank through a well-designed wet system. Heritage Tanks like this include a gutter system to create a valuable extra catchment area.

Whilst large round tanks provide economical water storage they can be difficult to move around. This 14000L tank is too wide to be carried on a ute, and the delivery truck couldn't make it up the narrow Fremantle laneway to the final destination.

No problem! After wrapping the tank in geotextile we simply rolled it several hundred metres along the back lane. Tank delivery drivers are very capable and experienced at getting their load into the right spot.

The 'Suburban' tank from West Coast Poly is a popular choice for collecting water in a larger garden. It looks nice, has a diameter of only 1420mm, and can be squeezed into a lot of spaces. Here it hides all the bins from view. We removed the existing gutter that drained in the opposite direction and rebuilt it to drain into the tank. Because there's heavy tree cover, an additional leaf filter (top left) is useful

We do industrial applications too. An existing off-the-shelf tank on a mezzanine level had split and was replaced by these two interconnected tanks that act as a header tank for a carwash, where the volume of water required can't be met directly off a mains supply. Mains water is supplied via a float valve (top-right) with an external pump. Using a heavier specification wall thickness makes the tank more suited to constant flexing through emptying and filling

AN awkward narrow spot just wide enough for this 800mm diameter tank to be squeezed in and collect water from two downpipes that was flooding the corner

The tank consists of an outer wall constructed of curved steel plates bolted together, with a waterproof liner (seen here folded up in blue) inside. The steel doesn't come in contact with the water, but simply holds up the internal liner. A 150mm thick level bed of sand is necessary to prevent any chance of damage to the liner

This 4500L tank is only 1350mm to the apex of the roof and can be easily concealed behind shrubs or trees. Although this example is obviously above ground, the low height does also make them suitable for use below a patio for example, as long as it can be got into position

Another example of the very popular oval-shaped 1500L tank from West Coast Poly. Attractive minirib design matches with the old weatherboard cottage and corrugated steel extension int he same colour seen at back-left. The oval tank fits well into spaces where a larger tank wouldn't. Here the brick paving was sloping and we had to relay the base to make it level.

A great fit for this small space between the house and garage. The tank takes rainwater into the top from two gutters on the left, and also from a lower gutter on the right into the side of the tank. WaterCraft excel in finding solutions that maximise the benefit of the tank and make it look smart.

These 2200L mini-ribbed tanks from Coerco are only 1200mm diameter. so can be fitted into a small space provided there's sufficient headroom, as there is here under the deck of a house in the hills.

The perfect use for an old swimming pool in the Perth hills! This tank was located in one corner of the filled area and will be used to water a new veggie garden. As the house is raised on stumps there was sufficient headroom to fill this high tank using a 'wet' system to bring rainwater from 8 downpipes.

Later the same day the second set of curved plates have been bolted on top of the first to bring the walls up to a standard full height of 2 metres. The 1mm thick plastic liner has been rolled out and pulled up over the top of the wall, where it'll be secured by the roof. Some of the outlet fittings can be seen here too. The tank is then filled with some water to give it a bit of weight

The client had an unused space along the 'services' side of their home and wanted to save water. This pair of 2500L tanks (in Surfmist) harvest water from 3 downpipes along the side of the house and feed water back to the hot water system. The available space meant that round tanks fitted better than the more normal slimlines.

A small poly tank with attractive minirib detailing to replace an older plain galvanised model. The tank stand provides a little extra height to increae the water pressure. Tank and woodwork colours go nicely together, and we always paint our pipework to match so the whole job looks the part.

The completed tank is then surrounded with stone (bluemetal, coloured stone or even crushed concrete) to prevent erosion of the sand pad. This tank is in Woodland Grey, and the colour is perfect for blending into the jarrah forest background

This weathered tank was recycled from another location. It takes water off a rear extension to the cottage via a wet system, but being slightly uphill the maximum fill level is reduced.

Aquaplate steel has a thin plastic membrane laminated to the inside of the corrugated galvanised steel plate to prevent corrosion.

The RT32000 tank from Coerco is 3950mm diameter and around 2600mm to fill height, so doesn't fit everywhere. Here the house is several metres higher than the tank so a wet system flows well. Tanks are used as a Shire-approved alternative to release of stormwater straight into the ground.

Tanks like this are available from 250L upwards. This one takes rainwater collected by a 'wet' or charged system from four downpipes and a submersible pump then pushes this water to a set of 4500L tanks at the back of the garden. It is then pumped from there back to the house on demand. An overflow dumps excess water into a drain if the pump can't keep up in very heavy rain, or fails.

Such a system is uncommon but comes into its own when the only location for a large tank is uphill from the house thus preventing a natural flow.

Perfect as a source of water for hand watering a beautiful north-facing courtyard
