Household water bills rose 62% on average from 2015 to 2025 across the nation’s 500 largest community water systems, the Virginia Mercury reports.
Those systems serve about 155 million people. The increase ran faster than overall inflation and more than twice the rate of grocery price increases over the same period. Bills also rose 19% faster than household incomes. In Louisiana, Maryland, New Hampshire and West Virginia, water bills grew about twice as fast as incomes. Average annual costs ranged from $286 in Idaho to $1,383 in West Virginia. For-profit providers charged more than publicly owned systems.
