en.Wedoany.com Reported - The American Water Works Association (AWWA) predicts in its latest report that if users bear the full cost of updating drinking water infrastructure, the typical household water bill will rise from $429 to $969 by 2050, with the figure potentially increasing further due to inflation. This estimate is based on a total national drinking water infrastructure investment of $2.1 to $2.4 trillion (in 2025 dollars), which could result in approximately 30.4 million households spending more than 2.5% of their income on drinking water, and another 53.5 million households exceeding the 1.5% income threshold.
The report, titled "Beyond the Replacement Era: Balancing Composite Infrastructure Needs with Household Affordability," notes that drinking water utilities currently have an average annual capital expenditure of approximately $33.6 billion. To meet all infrastructure needs, this figure must rise to about $90.2 billion, representing a 168% increase in capital investment, with an annual funding gap of approximately $56.6 billion.
The Infrastructure Investment and Jobs Act (IIJA), signed in 2021, provided $55 billion in federal funding for U.S. water infrastructure, covering projects such as lead pipe replacement and the treatment of per- and polyfluoroalkyl substances (PFAS). The act is set to expire on September 30, 2026, at which point funding injections for new projects will cease.
Beyond the IIJA, the State Revolving Fund (SRF) program and the Water Infrastructure Finance and Innovation Act (WIFIA) of 2014 will continue to operate. The SRF supports state drinking water projects through low-interest loans, with principal and interest flowing back into the same fund for redistribution after loan repayment. WIFIA provides financing for large-scale projects, with a minimum project size of $20 million ($5 million for small communities).
Despite this, only 3.9% of public water spending currently comes from federal sources. Compared to infrastructure sectors like airports and highway transportation, which receive substantial subsidies, the water sector receives a notably lower proportion of federal support. Adam Carpenter, AWWA's Senior Manager of Environmental Policy, stated that while the water industry has the capacity to alleviate funding pressures by increasing revenue, without external assistance to advance infrastructure upgrades, the costs will be borne almost entirely by users.
The Low Income Household Water Assistance Program (LIHWAP), funded by the COVID-19 relief bill, helped over 1.5 million households avoid service disconnection due to unpaid bills. The program ended in March 2024. Restoring a similar program could subsidize households most vulnerable to service payment defaults. Carpenter emphasized that a successful industry transformation requires simultaneously achieving safe and reliable water supply and affordable pricing, ensuring access to this resource for all.
