Aurora's average monthly water bill is $40. Compared to transportation and housing costs, it is really cheap. Transportation expenses are $804 while housing costs are $1,688. The water bill in Aurora has increased close to 80% since 2008. This may be because Aurora has become more developed and dependent on a larger water supply. The water bill has outpaced the growth of income by more than 50%. That's insane! A low-income household must work 11 hours in order to pay their monthly water bills.
