U.S. water infrastructure faces $2.4-trillion investment need, AWWA report finds

(UI) - U.S. drinking water systems will require between $2.1 trillion and $2.4 trillion in investment over the next 25 years to maintain and modernize infrastructure, according to a new report from the American Water Works Association (AWWA)

The report highlights a growing gap between current spending and future needs, estimating that annual investment of $33.6 billion falls far short of the roughly $90.2 billion required—leaving a $56.6 billion annual shortfall.

Beyond replacing aging pipes and systems, utilities are facing increasing cost pressures tied to regulatory compliance, climate resilience, cybersecurity and treatment of more complex water sources. These factors are driving a structural shift in how infrastructure investment is planned and funded.

The report also warns that affordability is becoming a major concern, with household water bills projected to more than double by 2050 if funding gaps persist.

Federal financing programs, including the State Revolving Fund (SRF) and Water Infrastructure Finance and Innovation Act (WIFIA), are expected to play a key role in supporting future investment while helping utilities manage costs.

“The AWWA report reflects the reality that delivering high-quality water is growing more complex due to aging systems and evolving standards,” said John Griffith, president and CEO of American Water.

American Water said it plans to invest up to $48 billion over the next decade to support system upgrades, resilience and long-term service reliability.
