Call Before You Dig
Tennessee One-Call
Tennessee state law requires anyone about to engage in digging, excavation, moving of earth, demolition, or any type of activity that could damage underground utility lines to notify the utility companies in that area of their intent to dig not less than three business days before the work is to begin. The Tennessee One-Call system was created to provide advance notification service to member utilities, throughout the state.
You can reach CUD and other member utilities who provide gas, water, wastewater, phone, cable, etc. with one call to Tennessee One-Call at 1-800-351-1111. Tennessee One-Call will gather information from you about your planned work and send it to member utilities in the area where you plan to dig. CUD and other member utilities will then locate their facilities at the proposed excavation site with paint or flags so you can avoid them during your excavation. There is no charge to contact Tennessee One-Call and no charge for CUD to locate its underground facilities.
DIG SAFELY by calling Tennessee One-Call at 1-800-351-1111 three business days before you plan to dig. Then, wait for CUD to mark their lines. Respect the markings and dig with care.
Important: Always use extreme caution when you dig, and avoid digging within the utility safety zone. The safety zone is a strip of land the width of the utility, plus two feet on either side. Customer-owned service lines are not mapped and therefore may not be marked. Customer-owned lines include sewer laterals, underground electrical service lines, water lines, lines for outside lighting, invisible fencing, irrigation systems, customer fuel lines, or any other customer-owned line.
To report damage to a CUD utility line, call 626-4282.
