With three different capacities and the ability to join them together for larger capacities, we can almost suit any requirement.

22,500L is the largest in the range with a size of 2.4 x 4.4 x 2.5m high

11,700L is our mid-sized tank with that is 2.4 x 2.4 x 2.34m high

 6,700L is our small tank that is 1.8 x 2.0 x 2.08m high

All of our tanks can have a reduced height to fit the needs of the project.


Having the ability to be burried unground, sit nicely side by side or end to end, and have cars and trucks driven over the top. Our tanks are really versatile!

How it Works

Once you’ve selected what combination of tanks are required. Place an order with us. We will then send you a diagram for you to mark out any penetrations including a hole in the lid. Once that’s done, we will produce the tank to your specifications and deliver it to site. We will communicate with the crane company of your choosing to ensure that the crane isn’t waiting around.

What is the tank constructed of?

We use a special 50 MPa concrete that allows the tank to be poured in a single go. This means the walls and the base don’t allow any sepage and makes the tanks stronger.

How much do they weigh

The base tank weights are as follows. The total weight will depend on the lid thickness.

Size Maximum Weight
22,500L 12.2t
11,700L 7.1t
6,700L 4t
Where can we install the tanks?

Beneath lawns, gardens, driveways, garages, sheds, above ground and pretty much anywhere else. They can be partially or fully buried.

What can we use the water for?

Drinking, flushing toilets, washing clothes, washing your car, irrigation, filling up pools and pretty much anything else you use water for. We use food grade products to produce the tanks.

Do I need water filters?

It’s recommended. They are useful in removing small particles and prevent discolouration from the rainwater.

Do we need to clean the tanks?

They may need to be periodically cleaned. This will depend on many local factors, but speak to a professional local tank cleaner if your tank requires cleaning.
