America's Water Infrastructure Just Got Graded Again — Here's What a C- Means for You
The nation's civil engineers just re-graded U.S. drinking water infrastructure. It hasn't improved in four years.
Every four years, the American Society of Civil Engineers grades the condition of U.S. infrastructure like a school report card. In March 2025, drinking water infrastructure scored a C-, the exact same grade it received in 2021.
What's behind the grade
ASCE estimates the country's water infrastructure needs stand at $625 billion over the next 20 years, more than $150 billion higher than the EPA's 2018 estimate. A separate 2024 ASCE study found the funding gap between what's needed and what's being invested is $309 billion today, and is projected to grow to $620 billion by 2043 if nothing changes.
The Infrastructure Investment and Jobs Act put more than $30 billion toward drinking water improvements, lead service line removal, and emerging contaminants like PFAS, real progress, but not enough to move the national grade on its own.
What "aging" actually means in practice
Much of the country's water infrastructure was built more than 50 years ago. In practice, aging pipes mean more water main breaks (one occurs somewhere in the U.S. roughly every two minutes), more lost treated water, and more of the lead and galvanized service lines that utilities like DC Water are now working through multi-year replacement programs to remove.
What it means locally
National grades are an average. Some regions and utilities are ahead of this curve, others behind it. It's part of why checking your own utility's Consumer Confidence Report, and understanding your home's own service line material if you're not on a well, matters more than assuming national numbers apply evenly everywhere.
