Licensed Sewer Line Repair, Water Line Repair, and Lead Service Line Coordination for Naperville Homes and Businesses, Backed by Camera-Verified Diagnostics and Same-Day Emergency Response.
Sewer and water line problems get treated as the same general category more often than they should be. They’re not. A sewer line carries wastewater away from your home. A water line brings clean water in. They fail for different reasons, get repaired with different methods, and we handle both, along with the specific water line issue Naperville is currently dealing with citywide: lead service lines.

Where the City’s Responsibility Ends and Yours Begins
Every water service line has two owners. The section running from the water main in the street to your property line is City-owned. The section from that property line into your home is yours. This split matters for everyday repairs, since a leak or break on the City’s side is the City’s responsibility to fix, while anything past the property line falls to the homeowner. It matters even more right now because of what’s currently happening with lead.
Why Lead Service Lines Are Part of Our Naperville Water Line Work Right Now
For years, the City’s working assumption was that lead water service lines had been banned in Naperville construction since 1930, which kept the known inventory of affected properties relatively small, around 200 homes. A records investigation found that assumption was wrong. Lead lines weren’t actually prohibited until 1960, a thirty year gap that meant a lot more homes built in that window than anyone had accounted for. That discovery pushed the estimated number of affected properties up to as many as 2,000, with a significant concentration in the Moser Highlands and Scots Plains subdivisions specifically.
This wasn’t a minor bookkeeping correction. It changed the scope of an entire municipal program, and it’s exactly the kind of detail that matters if your home falls anywhere near that older construction window and you’ve never specifically checked your own service line material.
How to Actually Check Your Own Address
The City of Naperville maintains a searchable GIS map showing the known material of water service lines throughout the city. Entering your address takes a minute and gives you a direct answer rather than a guess based on when you think your home was built. Because the inventory has already been shown to undercount affected properties once, checking directly is worth doing even if you’ve heard secondhand that your home probably isn’t affected.
Two Paths to Replacement, and What Each One Actually Costs You
If your service line is confirmed lead, Naperville offers two distinct paths, and they’re worth understanding as genuinely different options rather than one obvious choice.
The City’s Lead Service Line Replacement Program replaces the entire line, from the water main to inside your home, at no cost to you, using City-contracted crews. This program launched in 2024 and is funded through an interest-free EPA loan, with an active project phase running through 2026 covering roughly 220 individual properties. Crews use digging methods wherever possible to limit disruption to your property and street, and homeowners receive a water filter pitcher and testing kit along with a required flushing protocol once the new line is in. Our lead service line replacement service can also coordinate this work directly if you’d rather not wait on the City’s own contractor schedule.
The Lead Service Line Rebate Program exists for homeowners who don’t want to wait for their turn in the City’s broader replacement schedule and would rather handle it on their own timeline using a contractor of their choosing. The rebate amount depends on which side of the street your water main sits on: $4,250 for a long-side replacement, where the main is across the street from the property, and $2,550 for a short-side replacement, where the main runs in the parkway directly adjacent to it. This path requires hiring a licensed plumbing contractor and applying for a Plumbing Permit through the City’s Transportation, Engineering and Development department before work begins.
The Legal Deadline Behind All of This
None of this is optional on the City’s end. Under the Illinois Lead Service Line Replacement and Notification Act, in effect since January 1, 2022, Naperville is legally required to replace every remaining lead water service line in the city by 2035. The City has pursued accelerated EPA funding specifically to move faster than that deadline requires where possible, which is part of why the current program exists at the scale it does rather than as a slower, decades-long trickle.
Water Line Problems Beyond Lead
Lead is the headline issue right now, but it’s far from the only reason a water line needs attention. Corrosion in older galvanized supply lines restricts flow gradually until low water pressure becomes a daily annoyance. A break or significant leak, whether from age, ground shifting, or freeze damage, can waste enormous amounts of water before it’s ever noticed above ground, sometimes showing up first as an unexplained spike in a water bill rather than any visible sign. Our water line repair and replacement service covers diagnosis and repair for all of these, lead-related or not, using trenchless methods where the situation allows for it.
Sewer Line Repair: What Actually Causes Failure
A sewer line fails for reasons that are usually less dramatic than a burst water main but no less disruptive. Tree root intrusion at aging joints is one of the most common causes, particularly in established parts of Naperville with mature landscaping near older sewer laterals. Grease and debris buildup narrows the pipe gradually until a slow drain becomes a full backup. Ground settling or shifting soil can offset a joint or crack a section outright. And simple age catches up with clay tile or cast iron laterals that have been in the ground for fifty years or more without ever being inspected.
A sewer camera inspection is the right first step for any of these, since it shows exactly where the problem sits and what’s actually causing it before committing to a repair method. From there, options range from sewer rodding or hydro jetting for a blockage without structural damage, to trenchless pipe lining for a damaged section that doesn’t require full excavation, to a complete section replacement when deterioration is too widespread for a targeted fix. Our sewer line repair services cover the full range, matched to what the camera inspection actually shows rather than a default assumption about which method is needed.
Repair or Replace: How to Actually Decide
For a sewer line, a camera inspection answers this directly. Root intrusion or a blockage without structural damage is almost always repairable. A collapsed section, significant offset, or widespread deterioration along much of the line’s length points toward replacement instead. For a water line, the same logic applies through leak detection and an assessment of the pipe material and condition: a localized leak in an otherwise sound line is a repair, while a lead service line under the new legal requirement, or a line showing corrosion and failure at multiple points, is a replacement conversation regardless of how the current symptom presents itself.
Before Any Digging Starts
Any sewer or water line repair involving excavation requires calling JULIE first to have underground utility lines marked. This isn’t a suggestion. It’s a legal requirement in Illinois, and skipping it risks striking a gas line, an electrical line, or a neighboring utility’s infrastructure during what should have been a straightforward repair. We’ve covered why this step matters and what the process actually involves in our guide on why your plumber should always call JULIE before they dig.
Working With a Licensed Contractor
Naperville’s permit process for water service replacement specifically requires a licensed plumbing contractor, not a general excavation crew or a handyman working outside their actual scope. That requirement exists for good reason: water and sewer line work touches the public system, involves permitting and inspection, and, in the case of a lead service line, involves a health consideration that’s worth taking seriously rather than treating as routine digging. A Naperville plumber familiar with the City’s specific permit process, the lead service line programs, and the utility locating requirement handles all of this as a standard part of the job rather than something the homeowner has to coordinate piece by piece.
Water and sewer line failures also contribute directly to a broader category of property damage worth understanding on its own. Our Naperville basement flooding guide covers how a failing line connects to water intrusion issues that go well beyond the line itself.
Whether it’s a sewer line that needs diagnosing, a water line leak, or a lead service line question, our team handles the diagnosis, the permit, and the repair, start to finish, for Naperville properties.
Frequently Asked Questions
How do I find out if my Naperville home has a lead water service line?
The City of Naperville maintains a searchable GIS map where you can enter your address to see your service line’s known material. Less than 1 percent of all water service lines in Naperville are known to be lead, but the City has been actively re-surveying its records after discovering the original inventory undercounted the number of affected properties.
Does Naperville really replace lead service lines for free?
Yes, for properties with a known lead service line enrolled in the City’s Lead Service Line Replacement Program. City-contracted crews replace the entire line, from the water main to inside the residence, at no cost to the homeowner, funded through an interest-free EPA loan.
What if I want to replace my lead service line sooner than the City’s program schedule?
Naperville offers a rebate for homeowners who replace their own lead service line on their own timeline, using a licensed plumbing contractor. The rebate amount depends on which side of the street the water main is located on, either a long-side or short-side replacement.
Is there a legal deadline for replacing lead service lines in Illinois?
Yes. Under the Illinois Lead Service Line Replacement and Notification Act, effective January 1, 2022, Naperville is required to replace all remaining lead water service lines by 2035. The City has pursued accelerated funding to complete this work sooner where possible.
Who owns the water line between my house and the street in Naperville?
The section from the water main to the property line is City-owned. The section from the property line into the home is the homeowner’s responsibility. This split matters for both lead service line replacement and general water line repair, since it determines who is responsible for what portion of a failing line.
Do I need a permit to replace a water service line in Naperville?
Yes. A Plumbing Permit for water service replacement or upgrade is required through the City’s Transportation, Engineering and Development department, and the work must be performed by a licensed plumbing contractor.
Should I always call JULIE before any sewer or water line repair?
Yes, for any work involving excavation. Calling JULIE to have underground utility lines marked before digging is both a safety necessity and a legal requirement in Illinois, and it applies to sewer and water line repair just as much as any other excavation work.
How do I know if a sewer or water line problem needs repair versus full replacement?
A camera inspection for a sewer line, or a leak detection assessment for a water line, identifies the actual extent of the damage. A single, localized issue is often repairable. A line with widespread deterioration, recurring failures, or a lead service line under the new legal requirements typically calls for full replacement instead.
