The average water bill is $74. It is very low compared to the transportation and housing costs. Since 2008, the water bill has increased by 108%. I think some of this cost came from increased maintenance on the old pipes, but I have no idea how they can jump 108%. The water bill has greatly outpaced the income growth, with income only increasing by 7% since 2008. A low income household would have to work 6.4 hours to pay the water bill.
