Hypothetically, what happens in a drought, when there is no water for anyone? Have your rights been violated? If so, by whom?
If it's rather described as a right to nondiscrimination in the distribution of clean water (with respect to some set of properties, which could include wealth or ability to pay, but likely couldn't include large-scale geographic location due to distribution logistics), then that actually starts to make sense and can be realistically debated.
