Factual information has stated that 3.575 million people plus are dying each year from water-related disease. Which is caused by a majority of our current water crisis. Most suffering people are linked to the limited access to safe drinking water, especially at the hospitals. The primary problems are due unsafe water and unhygienic living conditions, and bad sanitation. This can be prevented by improving water supply, sanitation, and hygiene around the world especially in in the developing world.
Clean water alone can reduce water-related deaths by 21%. Sanitation alone can reduce that by 37.5%, and hand-washing can
Because of this,
There is the 1.Life Straw_, which is a mobile personal tool, used to purify water. That removes 99.9999% of waterborne bacteria through the fine filtration process. The device does not require any electrical power, batteries or replacement parts. It cost $5 to manufacture and it allows one person to make surface water safe to drink for up to one year.
2. The Slingshot, created by Dean Kamen, it can take any bad contaminated water and make 1,000 liters of drinkable water per day. It generates small amounts of electricity, and one-machine costs $2,000. This one uses a miniature Stirling engine to function.
3rd device that is popular for purifying the water in the developing world, is this special machine that has a different approach than the others. The design is created off of the average distance a person in Africa goes to collect water 3.7miles. This internal filter is called the Midomo’s system. Powered off of the rotation of the wheels. One can carry 50 liters of water at a time.
There is the Lifesaver Jerrycan, this one has a ultra filtration purpose that can be portable. It can hold 18.5 liters of water and process up to 20,000 liters of water in its lifetime, which can provide enough safe drinking water for a family of 4 for about 5 years.
Another popular new innovation that is providing clean water for people in remote parts of the world includes the Stellenbosch Univ. Water Institute HOPE Project. It provides a point of use bottle. That is reusable, inexpensive, and includes replaceable water filters. These filers activate carbon and nano fivers to remove any bacteria, and other harmful matter. Leaving untreated water potable.
