Blue markings indicate drinking water lines that serve homes, buildings, or fire hydrants.
These are found:
- In front of residential lots

- Along main water distribution lines
Why it matters:
Breaking a water main or service line can cause:
- Flooding
- Service disruption
- Soil erosion
- Costly delays
Our HDD crews take extra precautions around blue-marked zones, using precise bore profiles and soft dig methods when needed.
