Construction and Underground Cables

The ground and parking lots around your building may hide underground power lines, communications cables, gas lines, water lines or other utilities. For major landscaping, foundations or piers, big construction projects, or fence posts... play it smart. Find out first where the utilities are.

One call will bring out crews from all member utilities to clearly mark their underground facilities in your work area. You'll quickly learn precisely where you can dig, and where you can't.
