The rainwater that falls on the roof is pure, but since it comes in contact with various SURFACES on its way to the storage units, some DUST and LEAVES may get carried AWAY with it. This can be reduced if the terrace is swept before the rains. However, even if some dust or leaves go into the sump, they do not cause any harm as long as the WATER is boiled before consumption.

Various filters can be utilised to remove such suspended pollutants from the rainwater collected to make it safer for consumption.
