Bottomless Tanks

[J.Johnson]

Over this winter, my family acquired a new summer range. The majority of the stock tanks are shot. All four watering sights are serviced by windmills and we are looking to water 150 pairs on a normal year. Rather than putting stock tanks in a series to get enough storage capacity we are looking at bottomless tanks, probably 30 or 33 footers.

So here's my question for members that have put some in. What method do you prefer for the bottom: bentonite, cement, or a liner? This is on sand if that has an affect on you decision.

Black plastic some sand and then bentonite.

Black plastic, some sand, bentonite, some sand

Concrete. It costs more, but the entire facility will last for 30+ years in our environment with minimal maintenance until the tank rusts out. We pour at least an eight foot pad around the outside to keep the dirt from working away as well.

Concrete with bentonite

Looks like the consensus is a combination of some type. Thanks for the input gentlemen.
