Water Purification Technology

The CEO of Life saver points out that building infrastructure of water is too costly to manage

It is estimated that slightly more than half of the population do have access to improved water. Only 8% of the household are connected to water services in Dar es Salaam. In the lack of investment, we need to come up with alternative way to provide people in need with improved water. This presentation offers profound insight into 'water'. Examples that mentioned below might not to be about exactly East Africa, but the importance of this technologies remain the same everywhere.

We need a different point of view in providing those who are desperate in need of drinkable water with fresh water.  In stead of shipping water, we can use natural ecological system. We don't actually have to implement the infrastructure that cannot be burned by developing countries.

 There is plenty of water available as long as we can purify water in the river into drinkable and fresh water.  Michael Prichard, advocator of  life saver bottle, asserts that we need provide people with technologies that enable them to get purified water by them selves rather than huge infrastructure.

All we gotta do is to implement straw.

As well as the life saver bottle, the same technologies in jerry can process 25,000 water meaning that family of four can employ this technology for as long as three years.   This is simply enough. Plus, it only cost, 1/2 cent per day. Technologically speaking, this technology pores are only 15nm, which the smallest bacteria and virus.  Previous technologies was filtering down to about 200 nm which actually allow the smallest bacteria and several viruses to get through the holes. Given that nothing can go through the hole of life sever bottle, people can turn to this bottle. People in Haiti, for example, spend a several hours a day to get water.  For the most part, however,  water available tends to be contaminated. The same water is used for doing dishes, doing laundries, and drinking.   People are forced to drink this contaminated water knowing that this will cause them to have serious disease. In fact, drinking dirty water is the most major causes of the child mortality.

UK government is spending £ 12 billion on foreign aid.  It can be argued that they are spending money on wrong stuff at the expense of many people's life. By making use of technologies, unnecessary decease and death can be avoided. In my view point, this technology shed light on development of infrastructure. In the face of serious shortage of water, waiting for infrastructure to be built might prove problem. Importance of stable provision of water would be the same regardless of countries. However, in case of emergency, such as when local public system was paralysed by natural disaster like flood, people who are at risk need to get access clean water as soon as possible.  Likewise, in the region where people are suffering from extreme poverty,  they are desperately in need of clean water. They need this tiny device more than infrastructure in the short run.  Therefore, in accordance with the purpose of aid, we seriously put more emphasis on this kind of technological breakthrough.
