I've been looking into ways to build a 30,000 gal tank for my garden. I live in a rural Texas area. Water from our well tends to slowly kill my plants. I use rainwater instead of the well, but my 4000 gal tank can't handle a Texas drought. A 30,000 gal tank would have gotten me through this summer.

I don't want to spend $20,000 to $30,000 on an industrial tank, though. This is a hobby, not a business.

I've looked at a lot of options. Today, I decided to look into 'above ground pools'. 20,000 gallon 'pools' seem to be available for less than $10,000.

I talked to DW. She said it would be ok, but only if the dogs could swim in it.

Am I on the wrong track?
