Each Water Wallet Token (WAWA) is a voucher for 20 liters of purified drinking water. WAWAs are sold exclusively here at US$1.00, that is US$0.05 per liter of water. The funds are used to establish water stations wherever people have no safe access to clean drinking water. WAWAs can be donated to schools, to hospitals, to communities, and even to individuals, who will receive 20 liters of purified drinking water per WAWA.
According to the United Nations, about 26% of all human beings have no safe and daily access to clean drinking water.
