Plumbing cells with running water would save more labor than it cost

Evidence

It would be regarded, perhaps, as a luxury too great for an establishment of this kind, were I to venture to propose the addition of a WATER-PIPE all around, with a cock to it in each cell. The clear expense would, however, not be quite so great as it might seem: since by this means a considerable quantity of attendance would be saved. To each prisoner, some allowance of water must necessarily be afforded, if it were only to drink, without regard to cleanliness. To forward that allowance by hand to two or three hundred prisoners in so many different apartments, might perhaps be as much as one man could do, if constantly employed. For the raising the water by pumps to necessary elevation, the labour of the prisoners would suffice. — Jeremy Bentham, The Panopticon Writings, 665
