Most of us take access to clean water for granted. But for nearly a billion people around the world, clean water is a commodity that’s hard to come by.In
places like Sub-Saharan Africa where diarrheal disease is a major
killer, access to clean water could save hundreds of thousands of
lives. LifeStraw, a portable water filter that you sip from, was donated to nearly amillion households in Kenya last April.
The water filter is easy to use, cheap to make, and adds to the growing
number of technologies developed by wealthy countries to improve the
lives of the people living in impoverished ones.
With a filtering tube nine inches long, one inch in diameter, and
weighing less than two ounces, even children can easily carry the
LifeStraw wherever they go. Just as its name suggests, you simply lower
the end into unfiltered water and drink through the mouthpiece at the
top. Unfiltered water goes in one end, clean water out the other. It
doesn’t need batteries and needs no extra parts. At least 99.9999% of
all waterborne bacteria and 99.9% of waterborne parasites are
eliminated. It doesn’t remove heavy metals, but it will reduce the
murkiness of the water by removing particles larger than 0.2
micrometers. The simple filter is good enough to pass US EPA water
filtration standards. And if used properly, a single LifeStraw can
filter at least 1,000 liters (about 264 gallons), or about what a person
drinks in a year. The water flow rate is high too, so you don’t have to
struggle to quench your thirst.
Worldwide, 884 million people don’t have access to clean water and
have no choice but to drink from local water sources contaminated with
bacteria and parasites. Each year 1.8 million people die due to
diarrheal disease, 200,000 from typhoid fever. Of those 884 million
without clean water, 37 percent are living in Sub-Saharan Africa. Only
about ten percent of Kenyans have access to clean water. The other 90
percent will either boil unfiltered water or, because building fires
requires firewood that must be bought, drink contaminated water. The
nearly 900,000 LifeStraws donated means 90 percent of all Kenyan
households will have easy access to clean water. Because they’re using
less firewood it will also cut down on local deforestation. The filters
are expected to last at least a decade.
It’s clear in the following video that LifeStraw is a godsend for the people of Kenya. Read more@singularityhub.com
