There is a number of ways to make these systems, and to have them deployed. the main issue with POU systems is that local waters in poor countries is normalcy contaminated. The reject from the current POU technologies, is hardness and minerals that is carried in the reject. These technologies lose about 35% to as much as 55% of incoming water, therefore are very inefficient. The innovative technologies out there, are normally more costly and also require the support that does not exist today. I am happy to discuss this with you if you like.

Have you tried carbon credits to finance water filters?
We at Nazava provide safe and affordable POU Water Purifiers. Costs per liter are only 0.17 USD cents.

We are always interested to learn about new technologies
Hi, This is indeed a very important topic. I would mention solar water disinfection. Experiments showed that exposing water to sun (in transparent bottles or bags) for 3-4 hours was able to disinfect the water. The work was done in cooperation with EAWAG in Switzerland. I would expect that there is more work done to date. You may check this out. Best wishes.
John,
This is an area we are also trying to explore, we have spoken to a number of Parties but no one appears to be taking it on board. We manufacture a point of use water purifier and are looking at various commercial models to ensure the project are sustainable.
