yes he does... but honestly would you rather pay 1 cent for every 3 litres, and spend 30 bucks once to filter it, or pay 2 dollars for every litre of bottled water. as it stands now bottled water is more expensive than gasoline. and most people need less than 3 litres of water a day to drink. so by paying less than a cent a day, he really isnt paying for it.
where the water bills really get ran up is with people flushing the toilet just because they dropped a kleenex in it, and from people taking huge long showers.
