Potable water scarcity in developing countries
Problems
Long/dangerous journey to get water
Lack of clean water sources
Poor sanitation

Physical water scarcity (dry climate)
Economic water scarcity - people cannot afford clean water
Example countries
Zimbabwe
Water and sanitation crisis in capital
India
Open sewers
Sewage entering rivers
Bangladesh
Water collected from contaminated surfaces
Mass poisoning due to arsenic in water
Existing products
https://en.wikipedia.org/wiki/Water_issues_in_developing_countries
AQUAtap water stations
Uses solar power to purify water
Modular, so can be scaled for the community
Requires no infrastructure
Is large and expensive. Does not solve water collection issues
Hydropack
Single use pack
Useful in disaster relief
Takes 12 hours to fill
Cleans and filters water
Water Wheel
A large rolling tank for collecting water, reducing the number of trips need
Can contain enough water for an entire family
Sustainable, no energy required, lasts 10 years
Reduces effective weight of water
Does not solve water filtration issues
Cycloclean, a bike which filters water
Provides a more efficient method of transport
Filters water so any source can be used
High cost
Takes many hours of cycling by water source to filter
Solution ideas
Water filters
Pumps, UV
Electric powered
Powered by movement
Improved water transport
Tools to easily and cheaply check for contamination
Filter water using energy from transportation
