The 'janta water technology', introduced by Sudesh Gandhi and Manju Mehta, scientists at the department of family resource management, Agriculture University, Hisar, Haryana, is an inexpensive water filtering technique for rural homemakers using locally available materials. It involves placing two earthen pitchers, one on top of the other on a stand. A tap is fixed using a holder in the lower pitcher and a filter candle is fixed in the upper pot. Water is filled in the upper pitcher which then gets filtered through the candle and gradually seeps and accumulates in the lower pitcher. This filtered water can then be taken out through the tap ( Changing Villages , Vol 15, No 3).
