Water and Sanitation

Angus, thank-you for your reply. I completely agree that both have advantages and disadvantages, making each more appropriate in different situations. I agree that smoke inhalation is a big problem in development, but I think this problem has the potential to remain with chlorine tablets, since people will still be cooking food. I asked about boiling water because I spent last summer in Kenya, and my experience was that many people didn’t treat the water at all (which was collected from roofs), while those who did treat water boiled it. I didn’t encounter any Kenyans using chlorine, perhaps due to the taste or the cost. Generally the water was then used to make chai so the hot temperature was a bonus in this context!

On the subject of filters, what do people think of hand-held filter systems such as the lifestraw?

The article quotes a spokesman from WaterAid as being very sceptical, due to the high cost. Is there not also a risk that it might increase water-borne infections such as bilharzia? On the other hand is it possible that donors are happier to see their money spent on what should be a permanent device (as opposed to a consumable such as chlorine), this increase in donations increasing the lifestaw’s potential?

Also, Alison would it be possible please to describe the multi filtration system used to treat the water at Emem?
