The cylinder is about 30' in diameter, and 5'-10' deep with a 3' berm constructed from the removed dirt. If 6' deep with a 3' berm it should hold about 45,000 gallons. I was considering using concrete (blocks or poured), but of course earthbags make a lot of sense. Water law means that I'll need to use a liner.
While earthbags have been used for basements and in some wet areas, I haven't seen them used in just this way. My concerns are:
resisting the compression of the surrounding dirt, especially when empty of water. need to plaster/coat the pond liner side of the earthbags width of the earthbags, and should they be tapered considerations for packing material ( I have good clay, not sand or gravel)
Any thoughts or experience using earthbags in this way would be greatly appreciated.

There have been many cisterns constructed with earthbags, both above and below ground. We have posted several articles about this: http://www.naturalbuildingblog.com/earthbag-cisterns/, http://www.naturalbuildingblog.com/earthbag-rainwater-cistern/
