Residential Clients: Privately Owned Utility Locating

Did you know, that privately-owned utilities account for 65% of all utilities?

A private utility locate is provided by a locate company, such as Diversified Underground, that is hired by either the excavator or the utility owner (homeowner). These locates begin at the demarcation point (the point where the utility becomes private from public). All markings past this point are the responsibility of the excavator or owner

Diversified Underground offers complete Utility Locating services for all privately owned utilities. This includes but is not limited to: Electric, Water or Gas (past the Meter), communications lines between buildings, wiring to irrigation valves or private lighting.

Engineering Locates

We provide accurate utility locates and digital mapping of all utilities in our client scope of work (see video below). Prior to every engineering locate, our locate coordinator will collect all individual utility owner prints/maps (within defined scope of work). These prints/maps are then given to our locator to review so that we may provide the most accurate locates/marks in the field. The final data can be exported in all common formats for mapping programs (GIS). The export data includes .csv, .kml, .shp, .txt, .xls or .xlsx for use in GIS or asset management software.

Frequently Asked Questions

What’s the difference between public and private utility locates?

  • Public utilities are located by the 811 system at no cost to you. Private utility locates cover everything past the demarcation point, where the utility line transitions from public to private property, including things like electric, water, or gas lines past the meter, communication lines between buildings, and wiring to irrigation valves or private lighting. Diversified Underground handles these private locates directly since they fall outside the public 811 system.

Why would I need a private utility locate if I already called 811?

  • 811 only marks public utility lines up to the demarcation point. Anything beyond that, on your own property, is your responsibility as the owner or excavator to have located before digging. That’s where Diversified Underground’s private locating service comes in.

Does Diversified Underground work with municipalities or large organizations, or just homeowners?

  • Both. They handle private locates for homeowners and excavators, and they also run contract utility locating for larger entities. Past and current contracts include Lockheed Martin, the City of Denver, Denver International Airport, City of Longmont Power, and Boulder Valley School District, among others.

What is Subsurface Utility Engineering (SUE), and do I need it?

  • SUE combines utility locating, hydro vacuum excavation, and data research to produce an accurate map of existing underground utilities, useful during design and engineering phases of a project. Diversified Underground performs SUE in accordance with ASCE Standard 38-02 and offers all four quality levels (A through D), so the right level depends on how much precision your project needs.

What do I get after an engineering locate is completed?

  • You’ll receive either a hand-drawn or digital sketch (digital available for a nominal fee) showing all located utilities, along with the original prints and maps collected from each utility owner during the process.
