We just opened the lid on this rolling cooler, and wheeled it into place so it could collect rainwater.

It gets too heavy to move when full, so we drained a few gallons of water into gallon jugs, using the drain valve. Easy!

Once it was light enough to roll, we rolled it out into the forest to drain the remaining water straight into the ground! So easy 

Here you can see the water draining into the ground.  You can open the drain valve and let it release water wherever its needed, and then close it and move it to another spot, or you can leave the valve open and roll it along, releasing water as you go. Another idea would be to fit a hose onto the drain valve (if you had the correct size hose or fitting), and then you could conduct the water into the ground using the hose to direct it.

Just throwing that out there in case someone finds it helpful 

Wishing You Peace, Abundance, and Aloha!
