Part 1 of “Small Towns, Big Pipes,” a series on the infrastructure crisis facing small communities across Illinois.

Every small town in Illinois runs on three systems almost nobody thinks about. One brings clean water to your tap. One carries the dirty water away. One moves rainwater off your street before it ends up in your basement.

All three are wearing out at the same time. And in towns like ours, from Kansas to Cairo to Galva, the money to fix them does not exist.

This is not a story about one village that let things slide. It is the same story in hundreds of communities across the state. The pipes were laid fifty, eighty, sometimes more than a hundred years ago. The people who paid for them are long gone. The bill for replacing them has arrived, and it landed on the smallest towns with the fewest people left to pay it.

How big is the problem?

Bigger than most people realize, because the problem is buried. A pothole announces itself every time you drive over it. A corroded water main six feet underground stays quiet until the day it doesn’t.

The Metropolitan Planning Council has estimated that Illinois needs $32 billion over twenty years for drinking water, stormwater and wastewater infrastructure. That is the highest drinking water need of any state in the Midwest. Illinois also has more lead water service lines than any other state in the country, a distinction no one wanted.

Nationally the picture is no better. The American Society of Civil Engineers grades the country’s infrastructure every four years. In its 2025 report card, drinking water earned a C minus. Wastewater got a D plus. Stormwater got a D, tied for the worst grade of any category they measure. By ASCE’s math, the country’s wastewater and stormwater systems needed $99 billion in capital investment in 2024 and came up $69 billion short. Roughly seventy cents of every needed dollar simply was not there.

Same rules, tiny budgets

Here is the part that hits small towns hardest. A village of 500 people has to meet most of the same water quality standards as Chicago. It has to test its water, file its reports, employ or contract a state-certified operator and comply with every new mandate the state passes.

Chicago spreads those costs across millions of customers. A small village spreads them across a few hundred water bills.

Take one example. In 2022, Illinois passed the Lead Service Line Replacement and Notification Act, which requires every community in the state to replace every lead water service line, with the work finished by 2044. The law made municipalities responsible for the job. It did not send money along with the requirement. Replacing a single line costs somewhere between $6,000 and $16,000. Even modest suburbs are staring at enormous totals. La Grange Park, a village of about 13,000, estimates its replacement program will cost $23.5 million over 17 years and has added a new monthly fee to every water bill to pay for it. Now shrink that village down to a few hundred people and run the same math. The fee per household stops being an annoyance and starts being a hardship.

Lead lines are just one mandate. The state has also ordered 21 Illinois communities to strip PFAS “forever chemicals” out of their drinking water by 2029. The village of Dupo expects that to cost at least $5 million. East Alton puts its price tag at $12 million. Nobody has told these towns where the money comes from.

The waste side is worse

Drinking water at least gets attention, because people drink it. What happens after the drain gets far less.

The Illinois EPA knows of more than 200 communities in this state with inadequate or nonexistent wastewater collection and treatment. Some rely on aging septic tanks that leak into ditches and streams. Others have what the agency politely calls “patchworks of decades-old underground wildcat systems,” pipe networks nobody designed, nobody mapped and nobody can afford to replace.

When these systems fail, the failure is not abstract. In Cahokia Heights, down near St. Louis, residents have lived with raw sewage backing into homes and yards for decades. Between 2014 and 2024, that one community accounted for a quarter of all sanitary sewer overflow reports filed with the Illinois EPA by smaller, non-permitted systems. And the rain that overwhelms those pipes keeps getting heavier. Intense rainfall in that region has increased by 25 percent since 1970, falling on drainage systems built for the weather of a different century.

The help that isn’t quite help

When a small town finally cannot put the project off any longer, it goes looking for assistance. What it mostly finds is debt.

The state’s main tool is the State Revolving Fund, which offers low-interest loans, not grants. USDA Rural Development serves towns under 10,000 people with loans stretched out as long as 40 years, sometimes paired with partial grants. Forty years is longer than much of the equipment will last. A town can still be paying for a treatment plant after the plant itself needs replacing.

True grant money exists, but it is scarce and fiercely contested. When Illinois opened a $56 million round of Community Development Block Grant funding for small-town water, sewer and housing projects in 2026, it was competitive money, available only to towns that could put together polished applications with engineering reports attached. The communities in the deepest trouble often cannot afford the engineering study required to ask for help. Meanwhile, federal support has been shrinking, including a $125 million cut to lead pipe replacement funding in recent budgets.

So the standard path looks like this: borrow millions, raise water and sewer rates to cover the payments, and hope the population holds.

The population is not holding

That last hope is the cruelest part. In the 2020 census, 87 of Illinois’ 102 counties lost population, with rural counties shrinking fastest. Downstate, only five counties outside the Chicago area gained people at all.

A water system’s costs are mostly fixed. The pipes, the tower, the plant and the loan payment cost the same whether 600 people are connected or 400. When the town shrinks, everyone left behind pays more. Higher bills push more people to leave, and the ones who stay tend to be older and living on fixed incomes. It is a spiral, and small towns across Illinois are already inside it. Aging systems leak too, which means residents pay to pump and treat water that never reaches a faucet. The Chicago suburb of Maywood has lost roughly 38 percent of its water to leaks, and some shrinking communities report losing half of what they pump.

What this series will cover

Throughout this series of articles, we will take each piece of this problem apart and look at it up close:

  • Drinking water: lead lines, PFAS and the true cost of the mandates
  • Wastewater: sewers, septic systems and the 200 towns the state left un-sewered
  • Storm drainage: old pipes meeting new weather
  • The funding maze: where the money comes from and why it mostly arrives as debt
  • The math: shrinking towns, rising bills and what small communities can still do about it

None of this is comfortable reading. But these systems belong to us. We paid for them, we depend on them and we will pay for whatever comes next. Understanding how we got here is the first step toward demanding something better.
