Water catchment options

[Les C]

Actually, some of the earlier forms of rainwater catchment may have been done with fabrics. I've seen situations where tarps were set up like lean-to's to catch rain and drain into a container. But it's more temporary than a metal roof. A carport/shelter structure may be a good longer term option than canvas, gathering less rain than a roof over a regular-sized house.

I wonder how long a yurt skin will hold up with the current levels of acid rain?
