How thick should my HDPE holding tank be?

I am having a high density polyethylene holding tank made...

THey quoted me 3/8" thick material, then I saw something on this board where it was made of 1/2" material.

Well, they want like $100 extra for the thicker 1/2" material.

The tank is 19" tall and about 15x15" at the top.
It tapers thinner as it goes down. So it will only hold about 12-15 gallons.

DO I REALLY NEED 1/2 INCH MATERIAL? Or will the 3/8 be enough?
The tank will sit on a small shelf and won't have much support on its sides.
