Frozen Well Line and Winter Thaw Around Duluth, MN
A hard Duluth freeze can leave a house with no water, or with a well line that has frozen in a shallow service pipe or an old well pit. This seasonal page is about that winter problem. If the taps are already dry, the first move is the same as on the emergency page: do not use the request form. Call a local well professional directly, or call [TODO: phone number]. This is a free referral service, not a well contractor. A local well professional receives your request, gets in touch about it, and performs the work. This site cannot promise when someone will arrive, and it does not thaw lines itself.
When you might need it
When the water stops, or a well line may have frozen, during a hard freeze, especially if the service pipe is shallow or the well was finished in a well pit.
What the work usually involves
- A phone conversation, then an on-site look, to decide whether a frozen line is likely, or whether the pump or tank has failed instead.
- Thawing or repair of the frozen line, if that is the work you agree with the provider.
- A conversation about what would reduce the chance of another freeze, which may involve the depth of the service pipe or an older well pit.
This site does not publish prices. Any price, quote, or appointment comes from the provider, on their own terms.
Why lines freeze, and what MDH says about depth
A well finished the way Minnesota now expects it to be finished is built to keep the water below the frost. The Minnesota Department of Health's Well Owner's Handbook (4th ed., updated January 2014) says pitless adapters and units attach to the casing below ground, usually 6 or 7 feet down, so the buried service pipe is deeper than the frost line and the water will not freeze. When a line still freezes, the pipe is often shallower than that, or the well is an older style.
MDH's property-transfer fact sheet notes that older wells were sometimes finished in well pits below the frost line, usually 5 to 8 feet deep, and that well pits are no longer allowed. A pit on an older property is a reason to mention it on the call. It is also a reason to have the well looked at once the immediate freeze is over.
How deep frost goes in Duluth is often discussed in terms of city water mains, which is not quite the same thing as a private well line. A Duluth Public Works utilities supervisor, quoted in the Duluth News Tribune article "Water main breaks cause wintertime woes," said frost in the city is often 4 to 6 feet deep and that water mains are typically buried 7 to 8 feet. That is a reported quote about municipal mains. It is not a measured study of private well lines. It does help explain why a shallow service pipe, or a poorly buried one, is a problem in this climate.
If the house already has no water
Treat it as urgent. The emergency well pump page is the companion to this one. The form on this site is not monitored continuously and is not for emergencies. Call a local well professional, or [TODO: phone number], and say whether the stoppage started in a freeze. If the pump still hums and no water arrives, or if some fixtures work and others do not, say that too. Those details keep the first call shorter.
Once the water is moving again, a longer look at the line, the pit, or the pump can wait for ordinary scheduling.
What to have ready when you request help
The town or address, the fact that you suspect a frozen line, and whether the house currently has water. If you know the well is in a pit, or you know the service pipe is shallow, include that. If you do not know, that is all right.

FAQ
The house has no water in a freeze. Do I use the form?
No. The form is not for emergencies and is not monitored continuously. Call a local well professional directly, or call [TODO: phone number].
Do all wells around Duluth freeze in winter?
No. A well with a pitless adapter or unit set usually 6 or 7 feet down, as MDH describes, is designed so the buried service pipe sits below the frost line. Freezing is more of a risk with a shallow pipe or an older well pit.
Are well pits still allowed?
MDH's property-transfer fact sheet says well pits are no longer allowed. Some older wells were still finished that way, usually 5 to 8 feet deep. Mention a pit if you have one.
Is the 4 to 6 foot frost figure a measurement of private well lines?
It is not. It is a Duluth Public Works quote about frost depth in the city, reported in the Duluth News Tribune, in a discussion of municipal water mains that are typically buried 7 to 8 feet. It is included here only as local climate context for shallow or poorly buried well lines.
