Action Required: Addressing Cheshire’s Aging Infrastructure and the Hidden Cost of “Invisible” Water

For most residents of Cheshire, the wastewater system is something rarely considered. Toilets flush. Sinks drain. Storms pass. Life moves on.

That is exactly how infrastructure is supposed to work.

But during a recent presentation to the Cheshire Town Council by the Water Pollution Control Authority and engineering consultants Wright-Pierce, town officials outlined a growing problem that can no longer remain underground—literally or politically.

Cheshire’s wastewater treatment plant is now roughly 60 years old. Although portions of the facility have been upgraded over the decades to meet environmental regulations for nitrogen and phosphorus removal, the broader sewer collection system—the nearly 100 miles of underground pipe carrying wastewater beneath our streets—has largely aged in place with minimal long-term rehabilitation.

The result is a problem engineers call Infiltration and Inflow, commonly shortened to INI.

In plain English, groundwater and rainwater are leaking into Cheshire’s sanitary sewer system through cracked pipes, deteriorated joints, failing manholes, and improper private connections such as sump pumps or roof drains. That clean water does not belong in the sanitary system, yet every gallon entering those pipes consumes treatment capacity and taxpayer dollars.

This is not simply a technical inconvenience. It is an infrastructure warning light.

Every major rainstorm forces the town to process millions of gallons of water that should never have entered the plant in the first place. Cheshire residents are effectively paying to treat rainwater. Even worse, excessive inflow threatens the operational stability of the entire system during severe weather events.

The consequences are now serious enough that the Connecticut Department of Energy and Environmental Protection has issued a Notice of Violation against the town for maintenance-related deficiencies. State officials reportedly warned that future funding assistance may be reduced or withheld unless Cheshire aggressively addresses the problem.

That should concern every taxpayer.

Historically, Cheshire has not lacked studies. Over the past quarter century, consultants have produced report after report identifying areas of concern. The challenge has not been diagnosis—it has been execution.

Deferred maintenance is politically easy because underground infrastructure is invisible. Roads, parks, and buildings generate ribbon cuttings. Sewer rehabilitation does not. Yet postponing maintenance only compounds the eventual cost. In infrastructure management, waiting for failure is often the most expensive option possible.

The WPCA is now proposing what appears to be the first truly sustained corrective effort in years: a multi-year “Find and Fix” initiative targeting approximately 40 miles of priority sewer pipe identified through flow monitoring and camera inspections.

The estimated investment—roughly $400,000 annually over five years—may initially sound substantial. But context matters. By acting now, Cheshire positions itself to maximize state grants that could cover up to 55 percent of eligible costs. Delaying action risks losing those subsidies entirely while allowing deterioration to accelerate.

That is the real financial equation before the town.

This issue also extends beyond homes directly connected to municipal sewers. Even properties on septic systems can indirectly contribute to the problem through regional drainage patterns, groundwater saturation, and storm water overflow conditions that place additional pressure on aging municipal infrastructure.

Residents should also understand that many private INI contributors are unintentional. Some homeowners may not realize their sump pumps or foundation drains are improperly connected to sanitary lines. Those individual discharges may appear insignificant in isolation, but collectively they overwhelm system capacity during storms.

The solution cannot rely solely on government. It requires public cooperation.

Homeowners can take meaningful steps:

• Extend downspouts away from foundations.
• Verify sump pumps discharge legally outside the sanitary system.
• Install backflow preventers.
• Improve grading around foundations.
• Maintain French drains and waterproofing systems.
• Report failing municipal drainage infrastructure when observed.

These are not cosmetic improvements. They are part of protecting the long-term resiliency of Cheshire itself.

The town has historically been viewed as a leader in utility innovation within Connecticut. Cheshire has capable engineers, experienced operators, and dedicated public works staff. But expertise alone cannot indefinitely overcome aging infrastructure.

Eventually, every community faces the same reality: pipes installed generations ago reach the end of their useful life.

The central question is whether a town addresses the problem strategically—or waits until emergencies dictate the response.

The encouraging aspect of the recent WPCA presentation is that Cheshire finally appears to recognize the scale and urgency of the issue. The less encouraging reality is that decades of deferred maintenance have narrowed the margin for delay.

Infrastructure failures rarely happen all at once. They happen gradually, quietly, and underground—until suddenly they are impossible to ignore.

The pipes beneath Cheshire may remain out of sight, but the financial and environmental consequences of ignoring them will not remain invisible for long.
