3. Wait for the Marks

The marking process typically takes 2 full working days, meaning if you contact Indiana 811 on a Tuesday, the utility operators have Wednesday and Thursday to mark the approximate location of lines. Each line will be marked in the color that corresponds to the appropriate utility.

Color code for utility markings. Red: electric. Yellow: gas, oil, steam. Orange: telephone and cable TV. Blue: water. Green: sewer. Purple: reclaimed water. Pink: temporary survey markings. White: proposed construction.
