U.S. water bills could double as climate‑driven drought strains supplies

A study published in *Nature Sustainability* examined Santa Cruz, California, and projected that climate‑induced water scarcity could push household water rates up to twice current levels by mid‑century. The researchers estimate that 7 %‑16 % of homes in the city could find water unaffordable by 2050, and that water rates have already risen three times faster than overall U.S. inflation over the past two decades.

Idaho water officials echoed the findings, warning that similar cost spikes could affect smaller communities across the Gem State. Idaho Department of Environmental Quality chief Tyler Fortunati highlighted drought, low snowpack, and depleted aquifers as drivers of higher bills, while bureau chief Mary Anna Peavey noted aging infrastructure and limited funding for upgrades. Both agencies stress the need for increased federal support to help utilities meet rising climate‑related expenses.
