"The Oxfam tap! This is an old story, but it deserves retelling. I have visited a few displaced camps like this one at Amida in northern Uganda, always to find water pouring unfailingly from the taps day in and day out - and often year in and year out.

The water supply is soon taken for granted by everyone using it, much as Oxfam takes for granted its long-time expertise in installing the systems. At Amida, more than 5,500 households were receiving 60 litres each a day from 12 tapstands supplied by 8 boreholes. Before Oxfam came to the camp, life was tougher. Geoffrey Omona lives in the camp, and has been taken on by Oxfam as a health facilitator. He knew what the camp was like before the water - and the latrines - arrived.

'People queued for hours at a borehole outside the camp. The place was dirty and unhygienic. The lack of water made cleanliness a problem, and people did not have latrines, or did not know how to use them and keep them clean. Most of the children were having diarrhoea. That's why Oxfam was so badly needed. Now the camp is very different. Now there's plenty of water. People have become aware how to use the latrines and to keep them clean.'"
