How have courts treated discrimination against nonresident water users?

However, there have been several examples where discrimination against nonresident water users has not been countenanced. In City of Montgomery v. Greene (1913) 180 Ala. 322, 329-330, 60 So. 900, 902 the court ruled that once a municipality attempts to supply water beyond its corporate limits, it must be with uniformity and without discrimination. A different rate fixed wholly upon corporate lines as the line of demarcation, in the absence of physical differences, was an unreasonable classification. ⁸
