Whether you are planning to do it yourself or hire a professional, smart digging means calling 811 before each job. Homeowners often make risky assumptions about whether or not they should get their utility lines marked, but every digging job requires a call – even small projects like planting trees and shrubs. The depth of utility lines varies and there may be multiple utility lines in a common area. Digging without calling can disrupt service to an entire neighborhood, harm you and those around you and potentially result in fines and repair costs. Calling 811 before every digging job gets your underground utility lines marked for free and helps prevent undesired consequences.
Call 811 from anywhere in the country a few days prior to digging, and your call will be routed to your local One Call Center. Tell the operator where you’re planning to dig, what type of work you will be doing and your affected local utilities companies will be notified about your intent to dig. In a few days, they’ll send a locator to mark the approximate location of your underground lines, pipes and cables, so you’ll know what’s below – and be able to dig safely.

Why should I call 811 before every dig?
Don’t gamble with your safety — if you’re a professional excavator or a homeowner, smart digging always requires a call to 811. Knowing where underground utility lines are buried before you dig will help protect you from injury and prevent damages to utilities, service disruptions and potential fines and repair costs. Whether you’re planting a tree or shrub, or installing a deck or pool, every job requires a call—Even if you’ve called before for a similar project. The depth of utility lines varies, and there may be multiple utility lines in one common area. Marked lines show you the approximate location of underground lines and help prevent undesired consequences such as injury, service disruptions to an entire neighborhood, or costly fines and repair costs.
