Ranchi, Jan. 3: Kalawati Oraon is still living a dream. She has clean potable water on her doorstep, something she never had for her entire 38-year-old life. Till a few months ago, Kalawati, with other women of hilly Kothi Tola village in Keredari block, some 80 km from Hazaribagh, trekked down hilly pathways in search of water. Today, her trekking days are history. Thanks to a unique hand pump developed by Hazaribagh-based Col (retired) Binay Kumar, which uses hydraulic energy to lift water. In a village where electricity, roads, public transport and other essentials are complete no-shows, the pump is perhaps their greatest miracle in recent times.
