The Bill Coming Due for America's Buried Water Pipes

Most public works show their condition on the surface. A bridge rusts where drivers can see it, and a cracked road is felt by every car that passes over it. Water mains are different, because they fail underground. A pipe laid when a neighborhood was new can corrode for decades before the surface shows anything at all. Then a main gives way, a street floods, and a repair crew works through the night on a pipe that may be older than anyone on the crew.

This is not a rare event. Across the United States, a water main breaks roughly every two minutes. The American Society of Civil Engineers, which grades the nation's infrastructure every four years, gave drinking water a C- and wastewater a D+ on its 2025 report card. Those grades describe systems that work most days, while carrying a growing backlog of pipes and plants that should already have been replaced.

The backlog has a price. The Environmental Protection Agency surveys every state to estimate what water systems would need to spend over the next twenty years to stay safe and reliable. The latest assessment puts that figure at $625 billion, and distribution pipes, the buried mains under the streets, account for about two-thirds of the need. The money is not for showpiece projects. It is mostly for digging up and replacing what earlier generations installed.

Who pays? In the United States, mostly the people who use the water. Most utilities are run as enterprise funds, meaning rates collected from customers, not general taxes, cover the costs. That design keeps water budgets steady, yet it also means every deferred project eventually lands on a monthly bill. Combined water and sewer bills rose about 24 percent from 2019 to 2024, and about 5.1 percent more in 2025, faster than inflation in those years. A widely used rule of thumb, built by adding two EPA benchmarks, treats combined bills above roughly 4.5 percent of a household's income as a high burden, a line that some low-income households have already crossed. EPA itself has no single official cutoff, and its 2024 affordability assessment used both 3 percent and 4.5 percent.

City councils face an unwelcome choice each budget year. Postponing replacement keeps rates low now, while the risk of failure keeps building underground. Replacing pipes on schedule protects service, yet the higher bills fall hardest on households with the least room in their budgets. Borrowing spreads costs across the decades a new main will serve, which seems fair, but the interest adds to the total and the debt binds future councils. Federal and state loan programs help, but they cover only a fraction of the national need.

The cost of replacement does not disappear, and what a city decides is when it is paid, by whom, and with how much interest added. Those decisions are made in public, at rate hearings, in bond elections, and in council votes that few residents attend. The ratepayers and voters of the next few decades will inherit whatever backlog remains, which makes the buried pipe network a civics topic as much as an engineering one.

1. According to the passage, how often does a water main break somewhere in the United States?
2. What grades did the 2025 infrastructure report card give drinking water and wastewater?
3. What share of the $625 billion national need is for distribution pipes, and why does the passage say the money is not for showpiece projects?
4. Why do pipe failures build up with less public attention than failing bridges or roads? Use a detail from the passage.
5. The passage says postponing replacement "keeps rates low now." Identify the intended outcome of postponement and one unintended outcome the passage describes.
6. A council chooses borrowing over an immediate rate increase. Using the passage, give one argument for that choice and one cost that comes with it.
