Guys, guys, we are only talking about a quantity of water for drinking ! How much does a family drink in a day, maybe a big family may consume 20 litres?
This is just a very small scale purification project of a small drum, or jar with the charcoal and sand filters, adn a little tap so it can be drawn off cleanly. We are talking of using an existing well, you throw a bucket down and collect your 20L a day and don't forget to keep the containers clean too, nothing complicated. then you put the filtered water in a nice big earthenware pot in the corner of the kitchen that allows the water to evaporate and it cools a little too, enjoy!
