In 2009, Joe Buchanan wrote the following report that was published by Right to Water, a New Zealand group working to support the human right to water. I'm publishing it again because it's pretty much fallen off the web, and because Kapiti mayor Ross Church is claiming that introducing volumetric charging will reduce consumption by 25%. I suspect he's rehashing these statistics which, as Joe's paper shows, don't stand up to even a cursory examination.
