The difference(s) between floods in the UK and Bangladesh are in Bangladesh, the dirty and clean water mixes together and contributes to the formation of diseases in the water. This also happens in the UK; however, the UK can afford to buy clean water for drinking in these cases.
The principle is 'dilution': with the first addition of clean water to dirty water, the dirty water becomes less dirty because it is diluted by the clean water. With the continued addition of clean water to dirty water, eventually the dirty water will be completely diluted and there will be no dirty water left; it will all be replaced by clean water.
