Every Small Town Is Heading Toward a Water Plant Decision. Most Start With the Wrong Question.

On May 15, 2026, the National League of Cities released its Municipal Infrastructure Conditions Report, and the water numbers are the worst in it. In 2022, 82 percent of city officials rated their own water systems satisfactory. In 2026, that figure is 39 percent. And 18 percent of officials now rate their systems not satisfactory, a category that sat at zero four years ago. The report itself lists the contributing factors: aging assets, rising construction costs, fiscal constraints, increasingly complex regulatory requirements, the high cost of underground infrastructure, and long upgrade timelines.

None of that will surprise anyone who has spent time in a small plant. What the report puts a number on is how fast the gap between what a system needs and what a town can afford has widened. It matches what the water sector is saying about itself: AWWA's state-of-the-industry reporting puts aging infrastructure and climate risks at the top of the list of concerns shaking confidence across the sector.

Here is the part that should focus every village council: per the same NLC report, local governments fund more than 98 percent of all capital, operations, and maintenance investment for drinking water and wastewater infrastructure, across more than 50,000 community drinking water systems and more than 16,000 wastewater treatment systems nationwide. There is no cavalry. Whatever your town decides to do about its plant, your town is going to pay for nearly all of it.

A drop from 82 to 39 percent in four years is not purely physical decay, and the NLC report says as much. Part of the decline is awareness. Applying for federal infrastructure money under the IIJA required engineering studies and asset inventories, and those studies documented problems that cities had not fully documented before. Officials are not more pessimistic because their systems suddenly fell apart. They are more pessimistic because, for the first time in decades, many of them are looking at an honest inventory of what they own.

We think that detail is the most useful thing in the report, because it cuts both ways. Data made the problem visible. Data is also what keeps the problem from being overstated. An asset inventory tells you a clarifier is 40 years old. It does not tell you whether that clarifier, with modern instrumentation and controls around it, can run reliably for another 15. The age of the equipment and the remaining usefulness of the equipment are different questions, and only one of them shows up on a spreadsheet.

An asset inventory tells you what you own and how old it is. Only operating data tells you what it can still do.

This is not an argument against building. Glen Carbon, Illinois just showed what the build case looks like when it is legitimate. The village board unanimously approved $11.735 million in general obligation bonds toward a new water treatment plant with a total cost of about $21 million, expected to process up to 3 million gallons per day. That is a capacity decision. If a community is growing into demand its current plant cannot meet, no amount of instrumentation changes the arithmetic, and we would never suggest otherwise.

The story also traveled well beyond the local paper. A post about it on X reached a large audience, which tells you something about the moment: a village bond issue for a water plant is now national conversation material. Residents everywhere are starting to understand that their town has a version of this decision coming.

What we would point out is the shape of the Glen Carbon numbers. Roughly $21 million, financed substantially through general obligation bonds, which means debt the town carries for decades. When the demand case is real, that is what responsible governance looks like. When the demand case is an assumption, that same bond issue is the most expensive way possible to solve a problem that a controls and monitoring upgrade might have solved for a small fraction of the cost.

Most towns start the capital conversation with "what should we build?" The cheaper first question is "what can the existing plant actually still do?" And in our experience, few towns can answer it with confidence, because the plant was never instrumented well enough to know. Nobody can say with confidence what the real hydraulic capacity is under current conditions, how much chemical the plant actually consumes versus what it should, which pumps are quietly degrading, or where the process loses efficiency between intake and discharge. In that vacuum, the engineering conversation defaults to worst-case assumptions, and worst-case assumptions price like new construction.

We have spent 57 years inside small municipal plants, and the pattern we see over and over is this: the mechanical backbone of a plant, the basins, the structures, much of the rotating equipment, often has decades of life left. What has actually failed, or was never adequate in the first place, is the layer around it: the instrumentation, the control systems, the monitoring, the telemetry, the chemical feed. That layer is what makes a plant knowable and operable. It is also, by a wide margin, the cheaper layer to replace. To be clear about what we do and do not do: we do not design or build treatment plants. Our work is the instrumentation, monitoring, controls, and chemical feed side of the problem, and we have been doing it as a family-owned firm since 1968, across more than 5,500 installed systems.

The practical sequence for a town staring at bad infrastructure ratings looks like this. First, instrument the plant well enough to generate real operating data: flows, levels, chemical usage, run times, alarm history. Second, let that data separate the equipment that is genuinely at end of life from the equipment that is merely old and undermonitored. Third, take the build-versus-upgrade decision to your engineer with that record in hand. Sometimes the answer will still be a new plant, and now you can defend that bond issue to your residents with data instead of adjectives. And often, for small systems in Ohio and Western Pennsylvania especially, the answer is a targeted controls and monitoring upgrade that buys the existing plant another decade or two at a cost the water fund can actually carry.

Not sure what your plant can still do?
