Stanford Study: Water Bills Could Become Unaffordable for Millions Within a Decade
Millions of American households may face unaffordable water bills within the next decade due to climate change and aging infrastructure, according to Stanford University research.

Millions of Americans could face prohibitively high water bills within the next decade, as climate change strains aging infrastructure and depletes water supplies. A study led by Stanford University researchers indicates that hotter and drier conditions could exacerbate current issues, potentially making water bills unaffordable for over one-third of U.S. households.
Water rates have already been increasing at three times the rate of inflation. The study suggests that climate change will intensify these pressures. "If you're already struggling to pay your water bill, and now it's going to be double what it was before because of climate change, you're going to really have a problem making ends meet," said Sarah Fletcher, a senior author of the study.
Researchers used Santa Cruz, California, as a case study to model the impact. The coastal city was chosen due to its reliance on local water sources and pre-existing drought-related restrictions. "Currently, the main way that utilities can pay for these additional investments is through increasing water bills," explained Jennifer Skerker, the study's lead author.
The analysis suggests that passing these infrastructure and reliability costs directly to consumers could push a significant portion of households into crisis. The study’s findings indicate that these affordability challenges could be more severe in Western U.S. cities than previously estimated, as warmer and drier weather increases demand while decreasing supply, forcing utilities into costly infrastructure upgrades.
The researchers emphasize that the current model of utilities covering infrastructure costs by raising consumer rates is unsustainable. They urge federal and state policymakers to intervene, recommending solutions such as grant and loan programs for utilities and direct assistance for low-income households to ensure continued water access.
