Water is an essential ingredient for everyday living. When Barbara first visited Njarange in the early 90’s, water had to be carried from the local river, a return journey of several miles, and there was no guarantee of its purity. There is now a supply to the village, but it is not constant. The area is often hit by drought and the supply to the village can be cut off for a week or more while water is pumped to a different area in need. Water tanks are therefore needed to store water when it is available, and each family needs water containers to have at home. To maintain purity, these must be cleaned and disinfected at regular intervals.
