Reservoir thickness for differing amounts of liquid?

[RealToaster]

Has anyone put together a guide on how thick reservoir walls should be to prevent liquid pressure damage based on: Amount of liquid, type of liquid, reservoir tile material, reservoir shape, etc? For example, the chart could say (I made up these numbers): Polluted Water, 4x4 tiles and below, 1 tile thick sandstone. 5x5 to 8x8 tiles, 2 tile thick sandstone. On up to 4 tiles thick which I've read will never break.

Apologize if this is listed somewhere but I couldn't find it. I feel like I am wasting space, time, and materials by making reservoirs too thick, and worse, when I've made them too thin.

Make it out of gas permeable tiles in a single layer and it'll never break, regardless of size.

True, but it may leak if a sand tile hits the gas permeable floor (at least in previous versions, didn't test in OU)

Here's the thread you want.

I think three normal tiles will never break.

Yep.  You could actually do 3 thick of Sedimentary Rock and they can hold anything lol

I have always just used 3 thick sandstone tiles, it has never been damaged either.

The game just doesn't check for liquid pressure when you have 3 thick of any solid tiles. I'm guessing it's to prevent the game from checking the whole map all the time.

I like to use granite. I have occasionally run into issues with large water drop volume causing damage but I've never felt the need to go three wide or deep with granite. Though, it's always an option. I like the gas permeable solution, though it's not always practical when dealing with temporary basins or when you're trying to reinforce on the watery side.
