U.S. faces massive drinking water infrastructure investment shortfall, warns AWWA report
The rising cost of safe water
Today, U.S. drinking water utilities are spending about $33.6 billion per year on capital improvements
As these infrastructure challenges mount, water utilities face a stark reality: they simply cannot meet the demand for investment under the current financial framework. Today, U.S. drinking water utilities are spending about $33.6 billion per year on capital improvements. However, the annual investment needed to meet the projected demands is approximately $90.2 billion, creating an annual funding gap of roughly $56.6 billion. A staggering 168% increase in capital investment is required to close this gap.
With federal funding falling short, contributing only about 3.9% of the total public spending on water utilities, the financial burden is expected to fall on local communities. Recent federal initiatives, such as the Infrastructure Investment and Jobs Act (IIJA), have provided some relief, but these funds are time-limited and insufficient to address the long-term needs of the sector.
Perhaps the most troubling consequence of this funding gap is the impact on household water bills. If the entire funding shortfall is addressed through increased water rates, average household water bills will more than double by 2050. The AWWA report projects that the average annual bill for drinking water could rise from $429 in 2025 to $969 by 2050, an increase of 126%.

This sharp rise in costs will have serious implications for household affordability. According to the report, if the funding gap is covered by rate hikes alone, an estimated 30.4 million households (21.5% of the U.S. population) would spend more than 2.5% of their income on drinking water services. This would put millions of families in financial jeopardy, exacerbating the already significant affordability challenge that many low-income households face today.
The report also warns that this scenario could push the affordability crisis even further, with millions more households spending a disproportionate share of their income on water. To mitigate these impacts, AWWA estimates that $13.6 billion per year in federal and state assistance will be needed by 2050 to keep water bills below commonly cited affordability thresholds.
