where to get 30 gallon water tank - cheap or free

[Captain Belly]

I'm looking for a 30 gallon tank to haul water to my trees in the yard. I have a 50 gallon, but it's too big and bulky for my garden tractor to pull. It will turn the trailer over on hills, even when the water level is half full. I would settle for a 25-30 gallon tank. I'm going to weld a low profile trail to fit said tank in. Here's what I've found:
1) Car washes buy soap that come in 30 gallon plastic drums.
2) Hospitals buy soap for sterile processing that come in 30 gallon drums.
If I can't find one of these businesses to give me one, I will need some more ideas.

Does anyone else have any suggestions?

Mine is a 25. It came with a pump and battery clips. I have seen people sell them in craigslist for cheap.

How about 5 gal. buckets with lids? We have a garden tractor and a small tow-behind trailer. We put 5 gal. buckets of water in the trailer, attach lids, and give each tree 5 to 10 gals. of water each. It takes a little longer since we have to go back and refill the buckets from our 250 gal. rain water harvesting cube, but our days aren't that busy!

UPDATE:
I went to a popular car wash in town, and they gave me a barrel that once had soap in it. Took it to a car wash (how ironic)..... and power washed the soap out until there were no more suds. I got the barrel for free. it was a 55 gallon barrel, since it had a sealed top on it, I can lay it on it's side (no more turning over the trailer).... VERY PLEASED..... esp with the price.
CAUTION: some car washes will have acid barrels (tire cleaning agent). Don't get those!!!! Acid is bad! The kids that were running the carwash that day, were offering to give me a corrosive barrel with residual acid in the bottom. Acid is the devil when you get it on your skin and elsewhere! (they didn't know any better). I kindly turned it down and warned of the acid contents. Anyway....... maybe this will help others.
