I was pondering a idea using a leak diverter tarp. We have several of these deployed where I work at, and the rain water collected is significant. I was thinking in a remote location with painters bis queen and the fitting below you could rig up a simple rain collection system for water procurement. The system would cost under $10 and would be compact. I could use one of my waterproof bags as a collector or bucket for the water, while my shelter is built.

Any ideas?

What's a leak diverter tarp?

As far as collecting rain water I would think any plastic tarp that channels the water to a bucket would work.

Very true, they use these in buildings that have a hole in the roof to temporary keep the water from getting all over the floor by diverting the water in a bucket. It's the same idea as the tarp to bucket but I was wondering if you made your tarp like a funnel if you could collect more water or not. The difference between the two is one has the above fitting with a hose for the water to go to and the other doesn't.

Should work like a champ. But then, so would rigging your tarp with a low side for water to run off of into a container...

True, I was wondering if you had a thin large surface are of bis queen in a slight funnel configuration if it would make any significant difference. I know the bigger the surface area the more water but I wonder if the configuration (funnel VS slope) would make any difference in collection of water.

My guess, being kinda uneducated in the math stuff, is that it would all depend on the size of the tarp. No matter what the shape, it should catch the same amout of water. But I may be wrong, I was wrong once before...

Dunno about where you guys live but here it's not likely to get a nice calm rain.

Gusty winds could do some SERIOUS damage to a lil leak diverting tarp made for indoors.

Just based on collection area: You would want the tarp to be as flat as possible and still direct the water. It's not so much surface area but projected area in the direction of rainfall. Cone or slope shouldn't make a difference, but for some reason I want to think the option with the center drain would be easier to setup. One hopes the rain is mostly vertical and not like I've been seeing the last couple of days - remnants of Gustav; 8.5 inches of rain total and 4 tornado warnings with 2 local siren activations today.

Very good points, That's for the advice, the contraption had stirred my curiosity at work, which is in a controlled environment and would probably not work in the field. It was a thought though.

They are pricey too, $70 for the cheapest one?

I know tarps are not cheap but $70 can get you a rather large one
