The bund or spill pallet capacity one to four 1,000-litre IBCs need in each country the calculator covers, and the pallets that pass.
One 1,000-litre IBC needs a bund of 1,100 litres under the 110 and 25 per cent rule, and so do two, three and four: the largest container governs until the fifth. Countries that size on the largest container alone ask for 1,000 litres; New Zealand, which sums the store, asks for the lot.

The smallest of our IBC pallets that meets the 110 and 25 per cent figure, with no drain opening.

|---|---|---|
| One IBC | 1,100 L | F21-IB-102, 1,100 L |
| Two IBCs | 1,100 L | F21-IB-201, 1,100 L |

Sized on the capacity the store is designed for, not the stock on the day. In the outer zone of a water protection area, a drum store needs 100% of the total. An IBC store sized for four needs its figure for four, even on a day it holds one.
Not under the 110 and 25 per cent rule used in the UK, Ireland, Australia and as common practice elsewhere. 110 per cent of one 1,000-litre IBC is 1,100 litres, more than a quarter of two (500), so the largest container governs until the fifth IBC, at 1,250 litres.
Under the 110 per cent rule, a sump of at least 1,100 litres for a 1,000-litre IBC. Under rules that size on the largest container alone, such as US SPCC or Germany’s AwSV, 1,000 litres plus any freeboard for rain.
Each country sizes containment on a different basis: 110 per cent of the largest container, 100 per cent of it, a share of the total, or all of it in bands. New Zealand sums every container at the place, which is why its figure grows with each IBC.
