Why is contacting 811 so important?

Frequently Asked Questions (Q&A)

Yes. You should call no matter how deep you are digging, since many cables and pipes lie at extremely shallow depths. Utah law defines “excavation” as “an operation in which earth, rock, or other material on or below the ground is moved or displaced by tools, equipment, or explosives.” The law specifies to contact Blue Stakes before excavating.

Utah law only requires utility owners to mark the lines that they own and maintain. This usually means up to the meter. Underground lines that extend beyond the meter or that are not connected to a meter are typically not installed or owned by a utility company and therefore may not be marked. These include water and sewer laterals, power to a detached garage or lamppost, sprinkler / irrigation systems, lines connected to a propane tank or septic system, etc.

Almost every job site will include some type of privately-owned underground pipe or cable. The excavator should inspect the property carefully and ask the property owner about private underground lines before digging. The excavator should consider hiring a private locator to mark private lines that could be in conflict with the excavation project. Areas where private lines are especially common include apartment complexes, mobile home parks, gated subdivisions, cabin communities, schools and universities, hospital complexes, industrial areas, government facilities and military installations.

Blue Stakes recommends that excavators perform a thorough visual inspection of the entire dig site area to determine if all underground utility facilities have been located prior to beginning excavation. Excavators should keep notes to make sure that each utility owner was notified and has responded. An excavator suspects the presence of unmarked facilities, he/she should contact the Blue Stakes Contact Center or the utility owner directly and request that the unmarked utilities be marked immediately.

To check for Electronic Positive Responses from participating member utility owners, go to Blue Stakes Positive Response page, click on the “Check your ticket’s responses” button and then enter the ticket number.  This will display a list of all participating member utility owners for that request, including if and how they each have responded to the locate request.

Member utility companies will mark their lines at no cost. If you need the lines remarked as you continue excavating, they will be marked again at no charge.

However, if you request the same area to be marked multiple times and do not excavate, the utility companies may bill you for their costs to mark the area.

You must contact the appropriate utility companies individually and ask them to mark their lines. To look up the utility owners in your area, use the Utility Contact Information Lookup page.

The depth of utilities varies by location and by type of utility. An underground pipe or cable may no longer be at the same depth as when it was originally buried if grading, leveling, erosion or other nearby surface activity has taken place. For that reason, Utah law does not require utility owners to indicate the depth of their underground facilities. Utah law does not specify how deep utility lines must be buried.
