(Phys.org) —For those with running water in their homes, water is light, rolls right through the fingers, easily pours out of the faucet, and gives us hygiene and hydration in minutes so that we go on about our day. For families without such access, water is a different story. Water is heavy. Water collection dominates the time women and their school-age daughters have to spare on any day. They have the role of water-bearers and they walk long distances, hours, back and forth, to rivers and streams, with pails and jugs on their heads. The water they get will be doled out carefully for drinking, cooking and washing that day.
