Once utilities are marked, don’t disturb them. They show exactly where not to dig.
Why It Matters:
Accidentally moving or removing markers puts everyone at risk — one misstep could hit a live utility.
Key Points:
- Never drive over, dig out, or cover markers.
- Use flags, cones, or barriers to keep the area protected.
- Request re-marking if paint fades or ground conditions shift.
- Treat utility markings as off-limits zones for excavation.
Utility Marking Color Code:
- Red – Electric power lines
- Yellow – Gas, oil, steam
- Orange – Communications (phone, cable, internet)
- Blue – Potable water
- Green – Sewer and drain lines
- Purple – Reclaimed water
- White – Proposed excavation area
- Pink – Temporary survey markings
✅ Markings protect more than just pipes — they protect lives.
Ask the Crew:
- Are utility markers still visible and undisturbed?
- Has anything changed that requires re-marking?
- Are we maintaining clear zones around all marked lines?
