Thintanks 3000lt  Slimline Water Tank

Designed to be non-intrusive and aesthetically-pleasing, these tanks can be configured in any quantity to achieve your desired water storage capacity. Moreover, Slimline water tanks are markedly easy to position in virtually any location, including alongside fences, against a house wall, as a landscaping item to form an internal courtyard or to screen a back yard. All Slimline tanks are proudly Made in Australia.

We have included in this guide the instructions for the freestanding as well as the wall mounted water tanks. For those that need a more practical solution we have also provided a PDF download at the bottom of this page.

It is important for all ThinTanks™ being the 1000 litre, 2000 litre and 3000 litre water tanks to stand on a solid base, that will not settle or move when wet.

The water tanks can be laid on sloping ground, along the length of the tank. Surface must be horizontal (LEVEL) across the width of the tank to allow the sides of the tank to be vertical.
