Why private utility locating matters (and why you can’t guess)
Private lines aren’t marked by 811
811 is essential, but it typically covers public utilities. Private lines on your property— like sewer laterals from the house to the street—often require a private locate.
One strike can derail a project
Hitting an unmarked line can cause expensive repairs, service disruption, delays, and serious safety hazards. Documented locating reduces risk before excavation begins.
Protect your property
Know what’s buried before you dig near the foundation, driveway, or yard.
Reduce safety risk
Identify buried utilities to avoid strikes and dangerous jobsite conditions.
Move forward confidently
Clear marking and documentation helps you plan next steps without guesswork.

Best times to request a private locate
Before excavation
Any digging project should start with public marks and private locating where needed.
Before foundation repair
Know where private sewer or water lines are before piers, drains, or excavation begins.
Before landscaping
Trees, fences, decks, and drainage work are common times to hit unmarked private lines.
Common project triggers

Foundation Pipe Mapping & Private Locates FAQ
Does 811 locate private sewer lines or private utilities?
Usually not. 811 typically marks public utilities. Private utilities on your property—like private sewer laterals— often require a private locate.
When should I request a private locate?
Before digging, before landscaping, before fence, deck, or mailbox installation, and before foundation repair or remodeling projects where excavation is involved.
What can you locate and map?
Common targets include private sewer laterals, water lines, traceable conduit, wiring, and other privately owned underground utilities. Some complex conditions may call for GroundTruth GPR scanning.
Do you perform repairs or excavation?
No. GroundTruth is inspection-only and locating-focused. We provide documentation and clarity you can take to the contractor of your choice.
How does this relate to sewer inspections?
Standard sewer inspections start at $200 and can answer many line condition questions. When a project needs both sewer diagnostics and advanced locating, the Sewer + GPR bundle is $1,100.
