|
|
Notify your local "one-call" center by calling 811 or making an online request 2-3 days before you plan to dig. USA will transmit information to affected utility companies - including PID. |
|
|
Wait 2-3 days for the utility companies to respond to your request. On average, between 7-8 utility companies are notified for each request |
|
|
Confirm that all affected utility companies have responded to your request by comparing the marks on the ground to the list of utilities notifed by USA. |
|
|
Respect the marks. The marks provided by the utility companies are your guide for the duration of your project. |
|
|
If you are unable to maintain the marks during your project, or the project will continue past your request’s expiration date please call 811 to ask for a re-mark. If you cannot avoid digging near the marks, consider moving your project to another part of your yard. |

What to expect from PID
- Within 2-3 days of your request to USA North, we will mark all PID services in the affected area using blue paint or flags: This includes water mains and lines that lead up to the water meter.
- PID does not mark any private lines (after the meter) - that service will need to be performed by a plumber or line-locating service.
- If you see the letters "CLR" in blue paint it means we are "clear" - there are no PID services in the dig area.
