Imagine that you must flee home at once. You may be fleeing violence, social tensions, poor environmental conditions, or even persecution. You and your loved ones may walk for several days to find safety, and may even go for periods without food.
What would you need to survive?
The answer is clean water. Finding drinkable water is one of the first steps in your journey to a new home. If you instead consume contaminated water, you risk exposure to several diseases. Drinking water unfit for consumption may not only harm your health in the short run — drinking unclean water may cause life-long health problems. And of course, these problems multiply if entire communities, or even cities, face these health problems.
