So my first burn in 2006 resulted in my carrying back tens of gallons of icky icky water from my camp of 10 people. Something leaked in the car, and it's never been the same.
After reviewing all of the impressive plans here before the 2007 burn, I was talked out of any of the pump-based designs by my camp-mates (the same people who 'handled it' the year before!
I did sell them on the Clothesline idea, (using old cotton T-shirts to dip in the pond and then pull up in the air to evaporate). And although our setup was rinky-dinky in the extreme, (two saw horses with rope tied between them, water bottles for ballast) I have to report that from an evaporation standpoint the system worked really really well. We didn't even get it set up until after the storms, so it's not like the excessive winds were much of a factor.
Initally our camp had a nearly identical pond system set up as last year, but instead of (not) handling the water of ten campers we had thirty
, people to deal with, including mostly first timers, who weren't familiar with either the GI Shower or the Whore's Bath concepts. (Oh, plus the neighbors who were enthralled by our mucho macho shower structure. They seemed to feel that as long as they brought more water, they were entitled to use it. I had to go have a friendly conversation about carrying that water back to Texas once they were "done with it!"
After adding the clothesline system, and dipping the rags only occasionally (I don't think any of my campmates paid any notice besides me!) There was no grey water to carry home this year at all; just the plastic tarp with dried crud to fold up and toss out.
I have to recommend it. We could have done with a much smaller pond, for one thing.
One note to those who will try it next year: all that sopping-wet material is heavy.
Make sure your clothesline structure is rugged, and easy to dip and pull back into place. I'm thinking about a circular design with concentric rings of clothesline that could fit a kiddie pool...maybe raised and lowered with a pulley like an outdoor umbrella...?
