This is a cute little feature, we read about in our permaculture handbook, Rosemary Morrow's Earth User's Guide to Permaculture. We had already made a reed bed to filter our waste water as described in an earlier blog, and all it needed was a little pond at the end of it, to collected all the processed water. The quality of this water was good enough for frogs, tadpoles and birds to fool around in.
We dug a pit the size of this old truck tyre and lined it up with plastic. Then we took an old truck tyre and cut out the inside of it, leaving just the outer rim intact. This wasn't easy and it took the use of a saw to cut away the metal and rubber in the tyre.
After settling in the tyre into place, we covered up the exposed black rubber with stones found on the land. And planted lemon grass on the edge.
A few months on, and this little pond happily gathers the water for a few reptiles and birds and makes a very pretty feature on our farm! Not to mention the lemon grass which we regularly use for our tea!
