All you need is a clay pot, two feet piece of pvc pipe and gravel of different sizes and sand.
Step one
This is clay pot that is used to make a bio sand water filter. As you see in the picture there is a whole drilled in center of it.
The plumbing of the filter is made up of one or half inch PVC, two PVC elbows or a flexible pipe and cement to fix the pipe in the whole of clay pot.Here I did not use any elbow I just heat the pipe and bent it into require shape
