Nominal vs Actual Capacity Explained

In order to get the actual capacity of your water tank, you need to factor in the volume of water lost when an overflow and warning pipe is fitted. This will give you the top water level. If the top level water lost was 200mm, this is deducted from the overall height. A 3m x 2m x 2m sectional tank would have an actual capacity of 10,800 litres because it will be calculated as a 3m x 2m x
