"A water bill is a far, far better piece of ID."
I'm not sure if this was sarcasm or not but in case it's not -
First off, utilities are trying to move us to paperless bills these days so neither a water nor other utility bill might be available.
Secondly, I occasionally visited the outsourcing site where my water bill and mobile bills were printed. Unused stationery was disposed of on a recycling bin outside. It would be very easy for someone to take a few sheets and knock up a false bill.
Thirdly, I worked in security printing for a while. No utility bill I've seen would count as secure base stationery. It would be straightforward for any jobbing printer to produce adequate fakes. In fact, I assume that photoshopped copies of most utility and bank stationery are in regular use by anyone wanting to establish a false identity.
