FAQ

Questions About Private Locates

What utilities are marked by 811 One Call?

The One-Call System does not mark utilities. The One-Call system only notifies participating member utilities. These participating member utilities will not mark private or non-member utilities. The utility locating companies notified will locate and mark only primary public utilities, so it's up to you to keep track of what else is on your own property.

Private Utilities are the buried lines after the meter or main lines. If you have a curbside meter then your property will not get marked by the participating member utility locators. Other buried utilities that generally are not marked include but may not be limited to: sewer lines, private lighting, sprinklers, fire mains, secondary electric lines to detached garages, and septic lines.

No. There will be a service fee for a private locate. The utilites are owned by you and its the owners responsibility to cover the cost to protect private undergound lines.

UNCCs primary purpose is to act as a messaging Center for the state of Colorado between excavators and underground facility operators for locate requests when excavation activity is needed, and to educate the industry and general public on the Colorado state One-Call law (Colorado SB 93-155). Part of UNCCs education plan is establishing Damage Prevention Councils (DPCs) throughout Colorado. Because UNCC is a non-profit, non-government organization, each DPC is expected to become fully self-funded.
