The WaterWear backpack is a backpack designed to make the transporting of water an easier task than it currently is. It is made of lightweight polypropylene and it has adjustable straps and can be stood up when filling with water. Additionally there is a protected spout on the bag to make for clean water usage. The positives are that this bag is easy to carry, convenient, and it keeps water clean for drinking use. This bag is also easily transported, making for cheap transportation costs and more effective distribution. However a serious negative is how little water the bag contains. It carries a little more than a fourth of the water that its counterpart does (20 liters while the Hipporoller carries 75.7 liters)
I believe this could be a great technology, but not for places that are too far away from water sources because the trip to and from the water would seem almost futile.
That being said, if I were given $10,000 to spend on addressing the water needs in developing countries, this technology would not be the first thing I would go to. While the product seems safe and reliable, it also appears to be not as effective as some of its counterparts. I would work on making sure that the larger containers were sanitized, and thus there would be larger amounts of clean water. I feel that there are more efficient ways to go about this problem, although the WaterWear backpack seems like a viable option for a more developed country in a crisis.
Hi Alex, I think you make a valid point that WW backpacks would be ineffective in areas where people live far away from the water source -- they will have to make more trips than when they used the tumplines/head carry/Hipporoller methods, and this means more time. In this case, sanitation and comfort is a tradeoff for time.
