Slimline Water Tanks

About this Tank

Why compromise on your storage capacity with a cookie cutter solution? Tankworks Australia has developed a unique made-to-measure option when the popular sizes don’t fit. You have the freedom to select the width, length and height of your tank to suit. Make the length just right for your space between windows, set the width to ensure you have enough space to walk past... the freedom and choice is yours.

The Slimline range of water tanks is available in popular colours and sizes up to 7000 litres. They are built for narrow spaces, usually to fit along the side of your house. Internal stainless steel cross bracing is engineered into the tank for maximum durability and strength.

Tankworks tanks are made with Bluescope Aquaplate steel, which comes with a 20 year corrosion warranty.  Add to that an industry leading 10 year construction warranty on all water tanks, and you have a long lasting solution that you can rely on. 

Wtih Tankworks, your tank will be made to suit your home, so you can select the location of the fittings to make the plumbing as simple and neat as possible.

Selecting the right Tank

One

Choose the largest tank that will fit into your available area.

Direct as much of your roof area as practical into your tank.

 
Two

Normal garden hosing can use up to 1000 litres per hour of water.

A 5000 litre water tank will therefore provide around 5 hours of watering time. Make sure the capacity of your tank will suit your water use requirements.

 
Three

One square metre of roof area will provide one litre of water for every millimetre of rain.

Maximising the roof area feeding your tank is the best way to ensure you collect as much water as possible.

 
Four

Be aware that every 1000 litres of water in your tank is one tonne of mass.

Considering the location of your tank, be sure not to place the tank in an area with unstable ground or too close to existing house footings. Refer to our data sheet.

 
Five

Remember that you will need to access the leaf strainer to clean out leaves.

This may be a consideration when deciding the height and location of your tank.
