In ancient ages, when the world was a giant ball to our saggy forefathers, they were afraid of darkness. It was an aura of unseen peril to them. Therefore, mankind discovered the way of setting fire to flame. When they felt the need of going from place to place faster, they invented wheel. Necessity is the mother of invention. The same thing goes on water also. There was a time when the environment herself was so pure that there was no need of purification of water. The more we started growing civilised, the more contamination in water started to be found.

This region of undeveloped countries uses various kinds of innovative and interesting ways to purify drinking water. You will be amazed to know about some of them:
Solar Ball: Jonathon H. Liow, a graduate from Monash University, Australia, during his trip to Cambodia in 2008, was moved by the poverty and unhygienic use of water and set mind on inventing some cheap and effective device to purify water. The Solar Ball is the fruit of this thought. Solar Ball is transparent in spherical structure. It is cautiously made in a structure with which it can absorb sunray from the entire 360 degrees. It has a tap in the middle of it. A Solar Ball can purify upto3 Litres of drinking water per day.
Ceramic Water Purifier: Ceramic Water Purifier is not only an innovative and simple way of water purifying but also it has a royal history of expansion and development with it. Sir Henry Daulton, an English businessman and inventor of Victorian period was instructed in the year 1835 by Queen Victoria herself to invent a water purifier for her personal use. There are mainly two types of Ceramic Purifier- in the form of pot and candle. Water is poured from one side of the filter and the water blocks the way of any larger contamination to get mixed up. Though bacteria, protozoa like bigger-cell components are barred by this technique, comparatively smaller cell components like viruses cannot be purified.
Life straw: Vestergaard Frandsen of Switzerland is the inventor of this life-saving yet handy ‘single-user’ water purifier, Life Straw. With a Life-Straw, a person can purify up to 1000 litres of water which is sufficient for a single person to consume the amount in an entire year. It is extremely efficient in eliminating mostly all, 99.9% to be specified, of water-based and water-borne bacteria, pesticides and other polluting particles. It is a plastic, cigar-like tube. The entire tube is made with hollo fibres which, while the water is sucked by a person from the water source, purifies the water particles down to 0.2 µm.
Water Purifying Bicycle: Cycloclean or Water Purifying Bicycle is a brilliant way of refining water with paddle-power. You just need to park this bicycle beside any pond, lake or any water source, then press the hose into the water and ride on it. Now, when you start paddling, by the power produced by your paddling force, the water to come up through the pipe, undergo a primary filtering and then be poured to the activated carbon filter. The final step is the purification through “micro-filtration membrane filter” and now you are free to store the purified water in pots of your choice.
Midomo: Can you imagine when we feel lazy to go to the aqua guard to have a glass of water, every single African citizen at an average covers a distance of 3.7 miles daily to quench their thirst? The rotation of wheel inside it produces the power which helps to purify the water. A single Midomo can purify up to 50 litres of water at a time. This process is approved to produce safe water according to the WHO-set standard.
It is pathetic but true fact that every 1 person out of 8 is deprived of getting pure drinking water and the more shocking fact is that 80% of fatal diseases come from water based bacteria. So, before assuring our future generation to gift new electronic gadgets, let’s promise them to provide a clearer source of drinking water.
