Call Before You Dig

It's safe. It's free. It's the law.

811 Call Before You Dig

For your safety, you are required by law to call at least two working days before you plan to dig so your underground utility lines can be marked.

Always call 811 before you dig. ​

Homeowners and contractors must call 811 before undertaking any excavation or digging projects.

  • Prior to calling 811, mark the proposed excavation area with stakes, flags, posts, or painted or chalked lines that are white in color and are clearly visible.

  • Call at least three working days before you need to start excavations or digging. Be prepared to give the type of excavation being performed and the specific location of the proposed excavation.

  • The 811 service will connect you with the state one-call center, which will alert participating utility companies such as electric, gas, cable and phone about the planned digging so they can mark the appropriate location of their underground lines, if necessary.

  • Remember, you are responsible for marking your private lines such as private electric drops, invisible pet fences, sprinkler systems, yard lights and gas grill lines. 

  • Local utilities will then come to your home or work site and mark the location of their underground lines using the following color codes: 

Pink-temporary survey markings PINK -Temporary Survey Markings
 
Red-Electric Power Lines, Cables, Conduit and Lighting Cables RED - Electric Power Lines, Cables, Conduit and Lighting Cables
 
Yellow-gas, oil, steam, petroleum or gaseous materials YELLOW - Gas, Oil, Steam, Petroleum or Gaseous Materials
 
orange-communications, alarm or signal lines, cables or conduit ORANGE - Communications, Alarm or Signal Lines, Cables or Conduit
 
Blue-water, irrigation and slurry lines BLUE - Water, Irrigation and Slurry Lines
 
Purple-reclaimed water, irrigation and slurry lines PURPLE - Reclaimed water, irrigation and Slurry Lines
 
Green-sewers and drain lines GREEN - Sewers and Drain Lines


  • ​​Check the area before proceeding with your project. If a member utility has not responded or if underground facilities are clearly present and not located, call your state one call center again to have the area located properly.​

What information will I provide when contacting 811?

After contacting 811, the One Call Center will contact the appropriate companies and a trained technician will mark the location of underground facilities with colored flags, stakes or paint at no cost to you.

 

Location

You'll need to know the county, city and/or township of the location, along with the street address and nearest cross street.

 

Type/extent of work

You will be asked to provide a description of the type of work and extent of the work you have planned.

 

Date and time

Provide the operator with some information about when you plan to start digging, including the date and the time.


​Now, you are officially ready to dig!

When digging, make sure to always dig around the marks, not on them. Some utility lines may be buried at a shallow depth, and an unintended shovel thrust could result in dangerous and/or costly consequences. 

Don't forget that time, erosion or root structure growth may shift the locations of your utility lines, so remember to call again, each time you are planning a digging job. Safe digging is no accident. Know what's below. Always call before you dig.
