Global Water
• Clean potable water is a critical requirement
for all humanitarian assistance missions.
• In 2010, The UN General Assembly declared
that, “access to clean water and sanitation is
a human right.”
• Almost 900 million people worldwide lack
access to clean water.
• Insufficient access to safe drinking water
kills and sickens thousands of people a day.
• Natural disaster emergencies displace
millions worldwide every year exacerbating
the current conditions.
Water Health Facts
• Almost 4 million people die each
year from water related diseases.
• 80 % of all illnesses in the
developing world come from water
borne diseases.
• About half the world’s hospital beds
are occupied by someone with a
water related illness.
• 1/3 of the world’s population live in
water stressed areas.
• In India over 1 lakh die of water
borne disease annually.
• Ground water in 1/3 of India’s 600
districts is not fit for drinking.

Current Approach Challenge
Domestic RO
• More than 3 million units
in use.
• Increasing at a rate of
25% per year
• Used in low TDS situations
Too Simple –
• Wastes water
Ineffective Purification
POU Needs a Breakthrough
RO is Not Always the Answer
• A great water treatment technology for
Commercial and Industrial uses, to many pitfalls
for low TDS POU
• RO Requires Pressure - Much Energy is Required
• Intermittent Use - RO Membrane Biofouls
• Removal of Healthy Minerals - RO Removes All
Salts
• Waste Water - RO Recovery is not optimized
POU Needs a Breakthrough
RO is Not Always the Answer
• India needs a breakthrough in filtration technology.
• High population of more than 1.2 Billion.
• Cannot afford to waste water.
Bottled Water Still Prevails
Simple POU Device
Expensive and Wasteful
Bottled Water Comparison
• Global sales of bottled water
account for over $60-$80 billion
each year.
• India
– More than 20 billion liters a
year.
– The estimated market value
of India’s bottled water
market is over 90 billion RS.
Environmental Impact
• 17 million barrels of oil used
to produce water bottles each
year in the US.
– Enough to fuel 1 million
cars/year.
– 2.5 million tons of CO2.
• 3 times the amount of water
to produce the bottle as it
does to fill it.
• Only 1 in 5 bottles recycled.
– 3 billion pounds of waste.
