Home-made biological water filter
Values
Selling things or giving things away for free is not as good as teaching
people to make their own.
- Apart from the product itself, they can gain:
- a sense of achievement.
- an appreciation for what they already have available to them.
- opportunities to help each other.
- not being exposed to global consumerism that may make them want more and
feel poorer, or could open them up to a new dependency on unsustainable
exploitative commerce.
This following table shows some of the differences between the the system of
teaching people to make their own filters versus the starting of projects to
manufacture and provide them:

Clay pots:
• Biodegradable
• Environmentally firendly
• Affordable at approximately £1.50
• Technology is local, sustainable, and timeless
|
Concrete:
• Dependent on cement production and CO2 generation
Plastic:
• Importing goods from abroad |
| Enjoying what we already have to hand |
Looking outside for a better life and better things.
Commercialism. |
Every family learns skills and knowledge
to pass on to others.
• Development organisation not essential for the use of filters
to spread and continue. |
A manufacturer and their relationship with development
organisations is essential. |

This clay pot filter design is meant for educating families who need to make
their own filters and is not to be used for manufacturing, distribution or
marketing of filters.
Clay pot filters are too heavy and fragile for
distribution, though the materials a family needs to make one can easily be
transported.
In projects where families don’t make their own, the
advantage of the clay pot filter design is lost and it should not even be
considered.
For these projects see the excellent work of CAWST who hold international
patent coverage and the best design for manufactured Bio-sand filters.
