I built a heckuva greywater system last year and had forgotten about one potential source of greywater for our theme camp ... Melted Cooler water. Do you think that it would be possible that instead of using the water source bucket to siphon from that you could run the hose into your cooler somehow and use the melted cooler water as the evaporated water? Then you are motivated to keep your beer/food cool, and simultaneously be filling your microswamp cooler water resevoir?
