Well, I don't think I need to know all that about your domestic bunker / water feature, but if it features wooden beams overhead, you can just staple plastic sheeting to them to form a curtain that suits your needs. It should keep most of the humidity on one side, even if you don't do a very good job of making it airtight. Kind of like a shower curtain, but a little bigger.
