In a previous post we discussed how you can filter water using a five gallon bucket. Today we’re going to look at how you can build one of these water filters yourself, for an emergency situation, like a natural disaster. Lack of access to clean drinking water kills 1.6 million young children each year according to Unicef.
The water filter we’ll build consists of four five gallon buckets, that work to filter successively smaller particles out of the water, until you’re left with relatively clean and safe drinking water. This is a relatively low-cost solution and in most circumstances preferable over having to boil water.
