Using a boot for water drainage
So, it appears that this was the case. The drainpipe’s conclusion must’ve broken off, releasing the water from the property. This person repaired the problem by adding an old leather boot to the pipe’s end.
Oh, and it appears that they also had the wherewithal to cut open the front of the boot so the water could flow out. It’s difficult not to be impressed by the craftsmanship and inventiveness here. Well done.
