This filter is constructed using two earthen pots(or any
locally available vessel). A filter candle is fitted in the
base of one vessel that is placed on the top of another vessel.
To increase the pore size of this candle, it has to be boiled
for half an hour in water before fitting it in the base of
the vessel. Water to be purified is poured in the upper vessel
or pot, which slowly filters through this candle and get collected
in the lower pot or the vessel fitted with a tap to use water.
Depending upon the demand the same filter would be provided
to the households and one would be kept at the school in each
village. Such water filters could be made more in number and
provided to the community at genuine rate if demanded.
Besides, the group of unemployed youth of the village could
be identified who would arrange the resources from their local
market and make such water filters to meet the demand by the
community.
This is another method to keep the drinking water purified
in which drops of bleaching liquid with 3% of available chlorine
or chlorine tablets can be used per litre of water.
