I believe the plucker doesn't utilize water?
First, yes the scalder uses water - it's about 160F so needs to cool before applying to plants and as T. says, it will be full of feathers, blood and shit. I would try to apply that water to a mulch pit near trees if my processing area wasn't so far away from useful trees.
A plucker requires water as a spray to keep the feathers moving away. That water will have huge numbers of feathers in it. The quantity of water would be very dependent on the number of birds, and likely the style of plucker. I don't own one and the odd time I've borrowed one, I've tried to set it up where the water can run to a suitably useful spot, and raked up most of the sopping feathers and composted them.
I would expect the plucker manufacturer to have some estimate of the quantity of water per bird. However, unless you put you and the plucker up on an elevated surface like a trailer, or have some kind of concrete pad with a drain system and a good filter ahead of it so it doesn't clog constantly, if you are talking a relatively small quantity of birds, this may make this cost prohibitive.
A plucker would seriously speed up the job an reduce the risk of repetitive strain injuries. Knowing approximately how many birds/batch you plan on doing at once, and how many times per year, would be helpful towards people making suggestions that will be relevant.
