From what I can find, he didn't say that exactly.

Here's what he really said:

"The one opinion, which I think is extreme, is represented by the NGOs, who bang on about declaring water a public right. That means that as a human being you should have a right to water. That’s an extreme solution. The other view says that water is a foodstuff like any other, and like any other foodstuff it should have a market value."

So he meant that, but didn't use those exact words.
