I am having a custom holding tank made by a local tank builder. It will be about a 24 gal tank. The last decision I have to make is to use 3/8" or 1/2" walls. The tank will be built from polypropylene.
The 1/2" wall will reduce internal volume by about 1.2 gal and weigh about 10 lbs more than a 3/8" tank, thus weight and volume are not a big issue in the decision. I will need to properly support the tank whether its 3/8 or 1/2 thus the structural integrity, although somewhat of an issue, is not a huge issue. Thus I see odor permeability as the primary issue. The difference in cost is $140. Not alot of money, but enough to make the question worth asking.
Any thoughts about what wall thickness to use?
