Water Affordability in the United States
The cost of water and sewer services is rising three times faster than inflation in the USA, and that expense hits low-income households disproportionately. Research by Georgia Tech economist Casey Wichman reveals that, for one in seven households, the monthly water bill comprises more than 4.5 percent of monthly household income---a threshold commonly used for determining water affordability---and that rises, on average, to 8.1 percent of monthly income for the poorest one-tenth of households.
