Sir: This refers to a recent report on social media saying: “When Cynthia Koenig, a young social entrepreneur from New York, learned that millions of girls and women around the world spend hours each day collecting water from distant places, she created an innovative way to help people in poor communities transport water. It’s called the Waterwheel. Koenig’s Waterwheel allows people to carry water in a 50-liter container compared to a five gallon (19 litres) jugs. Koenig estimates that the Waterwheel can save women 35 hours per week in transporting water. It also prevents physical strain that comes from balancing 40 pounds of water on heads for hours each day.” In places like Sindh where thousands of women are bound to spend precious time daily to fetch water from distant areas for drinking and other domestic uses, the Waterwheel would be a blessing. I suggest to the Sindh government to import Waterwheels in large number and distribute them free of cost to the needy women in far-flung areas of Sindh, particularly in Thar.
