Water Tank Measuring Guide
How to Measure Your Water Tank For a New Tank Liner
Water tanks are generally either round or rectangular in shape. Most often all that is required is to measure the internal dimensions, and it must be the internal dimensions as this is where the liner has to fit.
However if you can’t get access to the inside, you can measure the outside and note the wall thickness.
Round Water Tanks
The most common type of water tank is the round corrugated or concrete water tank. Measuring a circular tank is as simple as measuring the height, and either the diameter or circumerfence of the inside of the tank. Make sure to note which measurement you take.
If you can’t get access to the inside, just measure the outside and either measure or estimate the wall thickness.
We recommend you measure in units of either mm (millimetre) or m (metres).
Rectangular Water Tanks
Another common type of water tank is the rectangular water tank. Measuring a rectangular tank is as simple as measuring the height, width and length of the inside of the tank.
If you can’t get access to the inside, just measure the outside and either measure or estimate the wall thickness.
We recommend you measure in units of either mm (millimetre) or m (metres).
Measuring Your Centre Post Support
If you have a single centre post support, we need to know about that as well. For more than one support post, we can still make a liner, but it must be professionally installed.
When measuring in a water tank with a supporting pole, its important to have a reference point as the pole may not be in the centre and the tank line will have to be installed the right way. We suggest using something obvious like the outlet or inlet pipes.
Round Water Tanks
Remember to check that the two length measurements (L1 + L2) or (L3 + L4) added to the pole thickness is equal to the diameter of the water tank.
We recommend you measure in units of either mm (millimetre) or m (metres).
Rectangular Water Tanks
Remember to check that the two length measurements (L1 + L2) or (L3 + L4) added to the pole thickness is equal to the respective width and length of the inside of the water tank.
We recommend you measure in units of either mm (millimetre) or m (metres).

Can I Install My Tank Liner?
If you are a little handy with tools it is not too difficult to install your own water tank liner. This is possible for most water tanks that are structurally sound, safe to enter and have no internal roof supports. If the water tank has one central internal support, we can make a special tank liner to suit.
To help you have a smooth installation, we have made available a comprehensive step by step tank liner installation instruction guide and video.
If you don’t want to install your own liner, we can help with installation.
