We created a portable hand wash kit that reduced the amount of water needed for a hand wash drastically. Normal hand wash consumes 500ml of water per hand, we created a special technique nozzle which could help washing hand with only 70ml of water. Hence saved 430ml of water per hand.

1500 volunteers were stationed near outside lavatories and dining halls, so that we can close the loop on hand hygiene and save water.

Over 30 days, 1500 volunteers, provided 6.7 million hand washes,

and saved 3.3 million liters of water.
