Cheapest Material will give you Purest Rainwater


Sand bed filter is the traditional method of water purification Systems.

In a confined masonry structure, coarse riverbed sand, pebbles and aggregates are filled one above the other as layers separated by plastic mesh.

Rainwater is allowed at the top from one end and filtered water is drawn from the bottom at the other end.

Aggregates, sand and plastic mesh need to be taken out of the filter chamber periodically. These are washed in fresh water and sun dried before refilling them back in the filter chamber.
