Is this now my rebar should look?
 
Here is a video of guys making a coy pond: http://www.youtube.com/watch?v=ULfm0UQsvo0

My situation is a little different, because I'm using forms to get straight walls, but should my rebar look like theirs?

You did not give pictures to compare with.

It's a hole guys:

Outer dimensions on sides and bottom are going to be 4" wider than the form. My plan was to pour the floor first, so I could keep the form off the ground and lined up.

I haven't made the form yet, but I'm guessing it's going to be pretty heavy, because of the amount of 2x4's I'm going to use to brace it.

I think this is different than a basement wall because with a basement wall you only have pressure being exerted inward from the ground. This is going to hold water, so I'd think that would help support it (like the plastic septic tanks you have to floor as you backfill)

If it was mine, I'd either install a one-piece rubber liner under the slab and over the sides terminating it under what will eventually be you're "coping". Another option would be to place a pvc "waterstop" strip into the slab pour and use your "pool paint" on the interior of the tub.

As for rebar, it won't look like that unless you're going to be doing gunnite/shotcrete.........

It's for a reservoir. Plumbing is a non-issue. I just need to it hold water and not crack.

It will work, as long as you don't rely on the concrete itself to be waterproof......

Like emergency water storage? Why not come out with the whole story so people can give ideas?

You will need a lot of small rebar spaced closely with complete long splices/laps and a regulate(sp?) cast into the slab and wall. The closely spaced steel will minimize the amount and size of cracks. The square intersection with the slab and walls is asking for trouble. - That why few reservoirs or storage tanks are square unless they are precast and monolithic concrete.

You can get a better solution by digging a hole and having someone stick in a precast tank/utility vault and plug excess openings. After you dig the hole and put is some rock. it a few hour job to deliver, set and then you just do your thing. If it does not have to be huge and square, there are many options to use large precast manhole sections depending on your desired depth and volume - like a cistern.
