My son and I do a few competitions each year and I agree that there has always been a place to dispose of waste water. As far as clean up is concerned I copied an idea I saw at one of the competions and made a wash station using a laundry sink. It's pretty simple....I got a cheap laundry sink at Home Depot that that came with faucets. Bought a medium sized plastic garbage can, a fish pond pump and some plastic tubing to hook the pump to the faucets. I heat water on our turkey and dump it in the garbage can (be careful not to boil the pump), drop in the pump and turn it on. I did put a switch in the cord to the pump and mounted it on some plywood. We use the switch to turn the water on and off. The only other thing needed is a bucket under the sink to catch the waste water. Due to the large size of the sink, it really speeds clean up. One other thing, I cut a small notch at the top of the garbage can for the plastic tubing. This allows me to put the lid on and keep the water warm.
