811 Before Digging
Established in 1983, Tennessee 811 serves as the statewide official one-call center to notify underground utilities of proposed excavation. Tennessee 811 does not mark lines but functions as a communications link between member utilities and anyone excavating. Tennessee’s Underground Utility Damage Prevention Act (TCA 65-31-101) requires everyone who digs to contact Tennessee 811 at least three (3) working days’ notice before starting a project. Tennessee 811 processes the notification of proposed excavation and notifies their member utilities, or their contract locators, to mark their underground facilities prior to the excavation. This free service helps prevent damage incidents which can result in millions of dollars in property damage, the interruption of utility service, personal injuries, and even loss of life. Tennessee 811 is a non-profit governed by a Board of Directors.
How do I contact Tennessee 811?
Tennessee 811 is a FREE service. Contact Tennessee 811 by dialing 811 or (800) 351-1111, or submit a ticket online through the Tennessee 811 website before digging. Because some VoIP, internet-based phone systems, and Wi-Fi calling providers do not support 811 dialing, the toll-free number (800) 351-1111 is available as a backup.
The 811 Process
Safe digging is everyone’s responsibility, but excavators have more responsibilities under the law and higher risk if the proper processes aren’t followed. Submitting a ticket is the first step but it’s not the only step, and sometimes it takes more than just contacting 811 once. Make sure to follow these steps before digging.
Why should I contact 811?
Contacting Tennessee 811 allows a customer who plans to dig to receive the approximate location of underground utility lines to ensure safety while excavating. Knowing where underground utility lines are buried before each digging project helps prevent injury, expense, and penalties. The depth of utility lines may vary and multiple utility lines from different providers may exist in a single area. Simple digging jobs can damage utility lines and disrupt vital services to an entire neighborhood, harm those who dig, and result in expensive fines and repair costs.
Who should contact 811?
Regardless of whether you are a contractor, a homeowner, or a “weekend warrior,” you should always contact 811 prior to digging. From planting a tree or shrub to building a deck – if the job requires digging, you should contact 811 before digging
