Safe water is a scarce commodity, despite being a region where water is not scarce, much of the population uses unsafe water from rivers or springs of stagnant water. The most common ways to obtain safe water are wells or conditioning of natural water springs. For a large part of the population, it is difficult and very expensive to have these infrastructures in their homes or villages, so that sometimes the nearest safe water point is several kilometers away, which encourages them to drink unsafe water from rivers and unconditioned springs.
