More than 5 billion people worldwide will be affected by water shortage by 2050. Two and half billion people live without basic sanitation facilities. Global climate change is affecting many continents. The amount of cyclones are increasing and after floods and cyclones (Zimbabwe cyclone Idai), people drink water from contaminated water sources.
During emergency situations, people transport water over longer distances either from the well to their home, or from a water tanker to their tent. For this type of water transport, many different devices are used. Traditionally jerry cans, plastic containers, collapsible containers and buckets with lids and a faucet. All these devices are voluminous and the type of plastic is not durable. They often break and are affected by weathering deterioration. Buckets and jerry cans are difficult to transport (bulky) and in flooded areas, buckets and jerry cans cannot be dropped by air
The market for a solution in impact space of WASH, can be calculated like this example, if the recommended intake of water is 1.9 liters per day and there are 7.5 billion people in the world. Using an average cost of $1.22 per gallon ($0.32 per liter) and a desired margin of 20%, the TAM for bottled water could theoretically be:
7.5 billion people * 1.9 liters * $0.32 price per liter * 120% margin * 365 days = $2.01 trillion TAM
