For the majority of us in the UK, we only have to turn on the tap to get clean water and we barely think twice about where it comes from. But day after day, thousands of people in developing countries - typically women and young children - have to walk miles to collect it.

The collected water is often filthy and puts children especially at risk of contracting deadly diseases. In fact, diarrhoea, from poor sanitation and dirty water, kills more children under the age of five than measles, HIV and malaria combined.

The international water aid charity, Just a Drop, delivers clean water projects to some of the poorest regions in the world. We build wells, hand-pumps, dams, pipelines and latrines and since 1998 we have reached an estimated 1.5 million people from Afghanistan to Zambia.

10 year old Eva, from Kenya, is just one of the children Just a Drop has supported. She explained, "Sometimes, after walking for five hours, we would reach the river only to be chased away by an elephant. We would have to return to the village empty-handed. Even when we were able to fetch the water, the distance was so far, I would often miss half of my lessons by the time I got to school."

With help from Just a Drop, Eva's village and school now has access to a well, which provides clean water for the whole community. One of the women, Mama Nico, explained the difference it has made: "Our village is now full of happy faces! The children can go to school and no longer have to walk 30km just to collect water. We are growing potatoes and tomatoes now which are a great addition to our diet, and Eva's mother is able to resume her small bead making business."
