What is UDIG?

UDIG is the recognized One Call Locate Center serving all of Flathead County, most of Lincoln County, and parts of Sanders and Lake County. The UDIG system is administered by the Flathead Valley Utility Coordinating Council (FVUCC).


What is the Flathead Valley Utility Coordinating Council?

The Flathead Valley Utility Coordinating Council is a non-profit corporation whose members are owners of buried facilities within the UDIG service territory. The FVUCC, Inc. contracts the Montana One Call Center to provide "One Call Locate Center" services.


Does UDIG locate everything that is buried?

No, UDIG doesn't locate anything. UDIG is a program that strives to serve as an efficient communications channel between excavators and the owners of buried facilities that could be damaged during an excavation. The owners of the underground facilities are the entities that are required by law to provide information about location of their buried systems. These owners may send their one employees to provide this information or they may contract a private company such as One Call Locators, Inc. to do that for them. In addition, UDIG members only mark their property. Privately owned power lines, gas lines, sewer service lines, septic tanks, water lines, satellite cable lines, private phone lines, underground sprinkler systems, etc. are not marked. The owner of those buried facilities is responsible for identifying their location.

What is the Montana One Call Center?

The Montana One Call Center is the answering service that picks up the phone when you call UDIG at 755-8344 or 1-800-551-8344. The Montana One Call Center is a private firm located in Kalispell, Montana, that contracts to provide Call Center Services. This is essentially an answering service that receives calls from excavators or anyone that has called UDIG to request that the location of underground utilities be identified to enable a safe excavation. The Montana One Call Center then notifies FVUCC members that have buried facilities in the general area of the excavation. The Montana One Call Center does not have access to detailed information about the location of underground utilities and other buried facilities. In addition, the Montana One Call Center does not have detailed information about the status of the field activity related to response to a locate request. The Montana One Call Center is the single point contact that receives notifications about proposed digging and excavations and notifies any FVUCC members that have buried facilities. The Montana One Call Center is the single point contact that will notify FVUCC members if an excavator calls back to seek further information about a line location request.
