Call before you dig – 811 nationwide

March 24, 2015




Know the potential dangers before you dig.

The snow has melted, the temperatures are moderating, and it’s time to get started on that springtime project list: planting a tree, installing a fence or building a new deck. Perhaps you’ve even made arrangements to rent that post-hole digger, and you’re all ready to go, right?

Well, not so quick. Make sure you haven’t forgotten an important factor before you contemplate digging: underground utilities.

You certainly don’t want to find out by accident that utilities are buried in your yard. Before you dig, please call the toll-free 811 line to have underground utilities mapped. The mapping service is free.

Digging without calling can result in service disruption to an entire subdivision, harm you and those around you and potentially result in fines and repair costs. Even if there are no injuries, the resulting utility outage can be an unnecessary nuisance. It’s not the recommended choice for meeting neighbors for most of us!

The Common Ground Alliance (CGA), a utility industry organization dedicated to preventing damage to underground utilities and ensuring public safety, collects statistics about underground utility damage incidents. The most recent report for 2013 shows about 25 percent of incidents occurred because no one reported the digging job in advance, and underground utilities were never mapped. Not surprisingly, most incidents occur mid-April through mid-October, according to CGA.

But when a call is made requesting location of underground utilities, 99 percent of the resulting jobs are completed without incident, the report shows.

Your homeowner insurance policy will likely provide liability coverage, up to the limit of your policy, for damage to others in the event you have an accident. But it’s always better to prevent an incident.

In most jurisdictions, a professional contractor you hired to complete a project is responsible for making the call to report a planned dig. But homeowners and other do-it-yourselfers also share responsibility for protecting underground utilities.

Every project, no matter how small, warrants a call:

  • Planting trees or hedges
  • Setting fence or mailbox posts
  • Excavating for ponds, pools or concrete constructions
  • Placing decking supports

flags-marking-underground-utilitiesWhen you call the centralized 811 number, you are connected to the “one call” service in your state. All 50 states, the District of Columbia, Puerto Rico and some Canadian provinces operate these services, allowing a customer’s single call to alert all affected utility providers. Additional information is available at, and in some areas you can submit information online rather than through a phone call.

Once you notify 811 of your dig – at least two but no more than 10 business days in advance – the appropriate utility representatives mark your property within 72 hours.

You can identify marked hazards by the color of the flags or paint:

  • Red – Electric
  • Orange – Communications, Telephone/CATV
  • Blue – Potable Water
  • Green – Sewer/Drainage
  • Yellow – Gas/Petroleum Pipe Line
  • Purple – Reclaimed Water
  • White – Premark site of intended excavation

Before you begin your excavation, remember to call 811 to have underground utilities mapped. You’ll protect yourself and your property, and maintain good relations with your neighbors.
