Hi Tien, Jay, and Hong,
Jen heard of this technology:
http://www.ted.com/talks/lang/eng/micha ... ilter.html
Their Jerrycans might be more relevant to our client:
http://www.lifesaversystems.com/jerrycan.html
(See for the AID version jerrycans)
According to their estimate, the cost for water processing is £0.09p per litre (less than 1 British pence, i.e. US$ ~0.015 ):
and the processed water seems to be directly drinkable.

"Small Village - All of your money goes directly to the provision of LIFESAVER jerrycans.
All the costs of distribution are born by the very generous help of the Mahvash and
Jahangir Siddiqui Foundation. At just £0.09p per litre the LIFESAVER jerrycan is a very
cost effective tool allowing families and villages to provide their own clean drinking water.
Your £135 contribution will provide 1 LIFESAVER jerrycan to a small village of 50 people. It will process 15,000 litres of clean sterile drinking water. At 1.5 Litres each per day this will last a village of 50 people for over 6 Months."
While for the Biosand Filter, the estimated cost for water processing is:
US$ ~0.01
(according to http://www.akvo.org/wiki/index.php/Conc ... and_Filter)
This is cheaper compared to the Jerrycan, but it seems people still need to boil the water before drinking.
How would you evaluate these two options for our client?
Thanks!
Best,
Tim

Hi Tim,
I was telling a friend of mine about the Biosand filter project, and
he recalled a TED talk about a different water sanitation technology.
Check it out:
