I have a toilet wand that I will use the first campground I stop at on the way home. I's a few feet long and it has a spinning nozzle that shoots water in a circular pattern in al directions. I have no doubt that this gadget will do the trick.
Also I want to clear one thing up I am not in a built up heavily populated area, there is a small wooded area in the back of the house that I use to dump the yellow water.
EDITThis is the wand I have. I have never used to to clean a large accumulation of poo but I highly recommend it for regular cleaning and maintenance.
