If a tag showed up on your door or a letter came with your water bill asking what your water service line is made of, you are not being singled out and you are not in trouble. Every water system in New Jersey is under the same state deadline, and your address is on the part of the list nobody has confirmed yet.
Why it arrived now, and why it will arrive again
New Jersey passed a law in 2021 that put every community water system in the state on a clock: inventory the service lines, notify the people on a lead or unknown line, and replace those lines by 2031. NJDEP turned that into two dates that repeat every year. Service line inventories are due to the state by July 10, and water systems must send notices to affected customers by August 10.
That is the entire reason these tags and letters go out across New Jersey in the same few weeks each summer. Systems from Bergen to Warren are working the same calendar. It also means this is not one-and-done: every address still marked unknown gets contacted again next year, and the year after, until somebody actually looks at the pipe.
The problem for your water system is simple. It has good records for the mains in the street and almost none for the pipe running from the curb into your basement. That half is usually the property owner's, so nobody at the water company has ever seen it. Asking you is the fastest way to close the gap, and the photo they want is worth more than the form, because a picture of the pipe at your meter answers the question outright.
How big the unknown pile is
Statewide, water systems have reported about 115,000 service lines already known to be lead or galvanized steel, and roughly 688,000 more whose material has never been confirmed, out of about 2.4 million lines reported in total. Nearly three in ten service lines in New Jersey are still a question mark. When you see towns all over the state mailing notices in the same month, that number is the reason. You can look up what your own water system has reported on NJDEP's mapping tool.
How to answer it in five minutes
You do not need a plumber, and you do not need to wait for an appointment. NJDEP tells residents with an unknown line that they can verify the material themselves. Go to your water meter, usually in the basement or crawlspace on the wall closest to the street, and look at the pipe on the street side of the meter. If your meter sits in an outside pit, look at the pipe going into the pit.
- Scratch it with a coin or a key, a few inches off the meter. Lead is soft, dull gray, and scratches to a shiny silver streak. Copper scratches to a bright penny color. Galvanized steel barely scratches and stays dull.
- Try a magnet. A refrigerator magnet grabs galvanized steel firmly. It will not stick to lead, copper, or plastic.
- Look at the shape. Old lead services often have a bulged section or a fat rounded bend near the meter, and no threads. Galvanized has threaded joints.
- Photograph it. Get the meter and about a foot of incoming pipe in one frame, in good light, close enough to see the surface. If you scratched it, get the scratch in the shot.
Silver scratch and no magnet means you are probably looking at lead. Dull gray that will not scratch silver and grabs a magnet means galvanized. Bright penny color means copper, and white, black, or blue plastic means plastic. If the pipe is painted, wrapped, or hidden behind finished wall, say that on the form. An honest "could not see it" is a real answer and it beats a guess.
Galvanized counts too
People are surprised the form asks about galvanized steel. Two reasons. Galvanized pipe that sat downstream of a lead pipe can hold lead in the scale on its inside wall, so it keeps releasing lead after the lead itself is gone. And on its own merit, after fifty or seventy years in the ground galvanized rusts closed from the inside. If your water pressure has been quietly getting worse for years, that is often what it is. We cover both on our sewer and water line page.
Who pays, and the part most people never read
A service line has two halves, the water system's side from the main to the curb and your side from the curb into the house, and historically you paid for yours. NJDEP is upfront that property owners may be responsible for their portion. But the state's own funding guidance goes further, and this is the sentence worth knowing: "Both the public and private sides of the lead service lines are eligible for replacement funding," and "Principal forgiveness funds are earmarked specifically for the customer side replacement."
In other words, there is state and federal money moving through the New Jersey Water Bank pointed at the half of the pipe that is normally yours to pay for. On top of that, NJDEP says water systems generally cannot replace their side and leave the customer side for later, except in an emergency or as part of a main replacement project, so when your line comes up the whole run should be handled at once.
So the boring advice is the profitable one: respond to the notice now, then ask your water system how costs are being assessed for your address and what funding it has, before you pay anyone. Some towns are working through funded replacements in the order people responded, our own borough in Hamburg among them. If there is money for your replacement, you should not be paying out of pocket for it.
What replacement day looks like
A typical single-family service line is a one to two day job. Markouts get called in and we wait for the marks. We dig from the curb to the house, set the new line on proper bedding at code depth, coordinate the connection and the inspection with the water system, then backfill in compacted lifts so the trench does not telegraph through your lawn a year later. Driveways, walkways, and patios get bored under instead of cut wherever the layout allows. The job is finished when the surface is back, not when the pipe is in.
Where we fit, and where we do not
JWSR is a private excavation contractor. We are not your water system, not your town, and not NJDEP. We cannot process your notice or hold your place in a funding line, and nobody from our company will ever knock on your door claiming to be from your town or the water company. If somebody does, that is worth a phone call to your water system.
What we do is the pipe. Water service lines are core work for us across Sussex, Warren, Morris, Hunterdon, Somerset, Passaic, and Bergen County.
