Bio-Water Filters
| Owner knows to leave cloudy water to stand before pouring into filter. | |
Many people, especially in rural areas, suffer from diarrhoea and other water-borne diseases such as typhoid, cholera, salmonella, hepatitis, meningitis, Giardia, Hookworm etc. These diseases usually come from drinking water that has bad germs in it.
Sand filters remove viruses, bacteria and chemicals more effectively than many modern filtration systems.
This article tells you how to make any suitable container into a bio-sand filter.
You can make your own filter pot at very little cost using skills that most people have and, apart from some cement and a piece of hose pipe, using the materials which you can dig up or collect from a nearby river or stream. The filter pot is made by plastering a mud mould with a mixture of sand and cement.
Although the mud mould for a filter pot can be made with hand-made mud rings or even with mud bricks, it is easier if you have a set of mould rings. This article shows how you can make a set.
I hope that this series of articles has got you interested in bio-sand filters for your community. There are a variety of ways in which different communities have adopted these filters. This article mentions some of our experiences in Uganda. These ideas may help you to introduce bio-sand filters to your community.
