What NC 811 covers, and what it misses
The state locate ticket, which we always file, covers public utilities to the meter or the property line: gas, electric, cable, phone, and municipal water and sewer mains. It does not cover the private lines that run from the meter to your house, and it does not cover well, septic, or irrigation. Those are owner-responsibility and the paint truck will not mark them. See the NC 811 guide for the full breakdown.
On a septic or well property this matters. Most of the utility risk on a rural piedmont property is not the public lines; it is the private ones. Before the job we ask you to walk the yard with us and point out the general path of everything private. We do not need centimeter accuracy. A rough line and depth estimate is enough for us to work safely.
Septic field: how we adjust
A conventional NC septic drain field has laterals buried twelve to twenty four inches down, spaced roughly six to ten feet apart. Grinding over a field is common; grinding through a lateral is a real problem. Our defaults on a septic field:
- Reduced depth. We cap the grind at eight inches unless we know the laterals are deeper. Turf depth is usually enough anyway.
- Smaller machine. A tracked grinder that spreads weight, not a wheeled unit that concentrates it under two tires.
- No parking on the field. The truck and trailer stay on the driveway or a bearing surface, not on the field itself.
Septic tanks are handled separately. The tank lid is a hard no-grind zone. If the stump is on or partly on the tank, we plan around it and tell you before the visit what depth we can actually reach.
Water and well lines: the shallow-line problem
Municipal water service to a house is typically buried twenty four to thirty six inches, below any residential grind. Private well lines and older service laterals are a different story. Some 1970s and older piedmont homes have water service as shallow as twelve inches, especially where the line runs under a driveway edge or a landscape bed.
Well head plumbing, pressure tank feeds, and irrigation zones can be as shallow as six to eight inches. Any of these directly under a stump is a stop-work condition until we know where the line actually is. We would rather leave a partial stump than take out your water.
The photos we need before we quote
For any stump near a utility, the quote request should include:
- A wide photo of the stump with the yard context, so we can see the septic tank lid, well head, hose bib, or irrigation valve boxes nearby.
- A close photo of the stump base at grade for measurement.
- A brief note in the description saying which utility is closest and roughly how far. "Septic tank lid about eight feet to the south" is exactly the level of detail we need.
With that we can either quote confidently or come back with a specific question before the visit. Read how to measure a stump before requesting a quote for the photo and measurement standard.
When we cannot grind to full depth
If a shallow utility runs directly under the stump and cannot be routed around, we grind to a safe depth above it and stop. A partial grind is not a bad outcome; the visible stump is gone, the yard is level enough for turf, and no one had to dig up a water line. We will always tell you the depth limit before we run the machine, and we will price the job for the depth we can actually reach.
