The sytem like that would cost big $ and take a serious ammount of time to set up and remove. Its not even a good idea for the hog industry in my view. If you just make a pond of crap in the field what good is that going to do? Sooner or later its going to need to be reloaded and spread. So why not just use a drag hose or wagon and knife it on some ground anyway? I think most places are wanting animal waste worked into the ground within 24 hours of placing it on the field.
