Bund Wall - an overview ScienceDirect Topics

The way the tank failed was explored by placing parts of the base,sidewall and bund wall next to one another in a reconstruction of this crucial part of the tank where the failure started (Fig.4.33).It was immediately apparent that the tank wall was severely distorted outward,especially when the inner tank wall was compared with the flat and unaffected outer or bund wall.Bunds and secondary containment - GPT EnvironmentalThe 110% rule is applicable where there is only 1 container stored inside the bund,in this situation the calculation is simple,the bund needs to have a capacity of at least 110% of the primary containment volume.For example if a tank has a capacity of 10,000 litres the bund
