Planning a home improvement project?
If it calls for digging, call Missouri 811.
Are you planting a tree? Installing a mailbox? Building a fence or deck? Or are you finally starting that garden that you’ve been dreaming of? Remember to contact Missouri 811!
For digging projects big or small, you need to contact Missouri 811 at least 3 working days before you start digging to avoid hitting an underground utility line. It’s free, it’s simple and it’s the law. Missouri 811 notifies its member utility companies to mark their underground facilities where you plan to dig. Missouri 811 does not locate or mark underground facilities. This is done by the member utility companies or their locators.
Safe digging is everyone’s responsibility. Failure to dig safely can result in costly damages and repairs, loss of essential utility services, and even serious injuries to you or your neighbors.
Notify Missouri 811
Request a utility locate online or by phone at 811 at least three full working days prior to excavation.

Missouri 811 will notify any public utility companies within your dig site while you wait the required time.

Do you know what's below?
Utility color codes are used to identify existing underground utilities in construction areas with the intent of protecting them from damage during excavation. This is done with either flags or a special spray paint, neither of which will cause long-term harm to your lawn.
The American Public Works Association (APWA) Uniform Color Codes for temporary marking of underground utilities are listed below:
Temporary Survey Markings
Electric Power Lines, Cables, Conduit and Lightning Cables
Communication, Alarm or Signal Lines, Cables or Conduit
Gas, Oil, Steam, Petroleum or Gaseous Materials
Sewers and Drain Lines
Reclaimed Water, Irrigation and Slurry Lines
The Tolerance Zone
Remember the tolerance zone when digging where underground utilities are located. This includes using hand tools only when feasible within 24 inches on either side of the utility (not including the width of the utility itself), and supporting and protecting the utility until work is complete.
