Is Your Home's Water Line Made of Lead?

If your St. Paul home was built before the late 1920s, there's a real chance the pipe carrying water from the street into your house is made of lead — and right now, the city will replace it for free.

This isn't a future proposal or a pilot program. Saint Paul Regional Water Services (SPRWS) is actively doing this work during the 2026 construction season, and it's one of the more genuinely useful pieces of plumbing-adjacent news for Twin Cities homeowners this year. Here's what the program actually covers, how to check your own address, and where the gaps are.

Why St. Paul has so many lead lines to begin with

Lead was the standard material for water service lines in Saint Paul from the late 1880s through the late 1920s — pliable, easy to work with, and durable in exactly the way that makes it hard to get rid of a century later. It's the same era of housing stock behind a lot of the plumbing quirks in older St. Paul neighborhoods, including the tree-root sewer problems common in Macalester-Groveland, Merriam Park, and Como.

SPRWS serves roughly 96,000 properties. Of those, about 17,000 — roughly 18% — have a confirmed lead service line, and another 4,500 or so have a line of unknown material that still needs to be verified.

What "free" actually means here

A service line has two owners in the eyes of the utility. SPRWS owns and maintains the section running from the water main under the street to your property line. From the property line to your water meter inside the house, you own it — normally, that private-side portion is your financial responsibility if it ever needs work.

Lead Free SPRWS changes that math for lead lines specifically. When a property in an active project area qualifies, crews replace both the public and private portions at no direct cost to the owner, funded through a combination of state, federal, and local money — about $35 million in state funding through the Minnesota Public Facilities Authority is supporting the 2026 work alone. The one thing required of the homeowner is signing a participation agreement authorizing the work.

That's a meaningful deal. The Minnesota Department of Health has estimated the statewide average cost of a private lead line replacement at around $15,000 per property when done outside a program like this.

How to actually check your address

You don't have to guess or wait for a letter. SPRWS maintains a service line material lookup, and a statewide inventory is also mapped through the University of Minnesota. Either tool will tell you whether your line is confirmed lead, confirmed non-lead, or unknown — and unknown lines are usually verified with a small pothole excavation before any work is scheduled.

If your property is included in this year's project, you should have already received a letter with next steps. If you haven't heard anything but suspect your home is old enough to qualify, checking the map yourself is the faster path — don't assume you've been left out just because your street hasn't been dug up yet.

The timeline, honestly

Lead Free SPRWS is a ten-year effort, not a one-summer fix. Since 2022, the utility has replaced approximately 4,500 lines, and 2026's target is roughly 2,200 more. At that pace, reaching all 17,000-plus known lead lines by the program's 2032 target is realistic but not guaranteed — funding levels from year to year will determine how close SPRWS gets, and state funding isn't locked in indefinitely.

Worth knowing: coverage varies significantly by city. Minneapolis runs its own water utility and its own lead line program, and as of this year it's dealing with a real funding gap — the 2026 state bonding bill allocated $15 million for lead line work statewide, well short of the $250 million that advocates had pushed for. Minneapolis is prioritizing daycare and childcare facilities and historically underserved neighborhoods first, which means some areas there will wait longer than St. Paul residents in an active SPRWS project zone. If you're outside the SPRWS service area, check with your own city's water utility directly rather than assuming the same terms apply.

Is it safe to keep drinking the water in the meantime?

Neither the Minnesota Department of Health nor the EPA currently requires a homeowner to remove a lead line on their own before a scheduled replacement, and water utilities add corrosion-control treatment specifically to reduce how much lead leaches into water system-wide. That's a meaningful layer of protection, but it isn't the same as having no lead line at all.

Lead exposure is a real concern, particularly for children and pregnant women, since it can affect the nervous system and development even at low levels. If you know or suspect you have a lead line, a few reasonable habits in the meantime: run the cold tap for 30 seconds to a minute before drinking or cooking if the water's been sitting overnight, avoid using hot tap water for infant formula or cooking, and ask SPRWS about getting your water tested if you want a direct answer rather than a general precaution.

A word on DIY here

This isn't a project to tackle yourself even if you're handy. Service line work involves excavation, connection to the public water main, and code requirements that call for a licensed plumber and, in most cases, city coordination — which is exactly why the free program exists in the first place. If you're not in a qualifying project area yet and don't want to wait, get quotes from more than one licensed plumber before committing to private replacement, since $15,000 is an average, not a fixed number.

What to do this week

Check your address against the lookup tool, even if you think you already know the answer — a fair number of "unknown" results turn out to be non-lead once verified, and there's no reason to spend money on private replacement without confirming the material first. If your line comes back as lead and you're not yet in a scheduled project area, there's no downside to reaching out to SPRWS directly to ask where your property sits in the queue.
