Private v. Public Utilities: What’s the Difference?
Mar 07, 2022
What is a public utility?
A public utility is owned by a company or organization that provides essential services. Public utilities typically include: electric, water, gas, communications and sewer. The public utility companies are responsible for maintaining their underground facilities. Part of that responsibility includes registering the utilities with 811 and locating in the public right-of-way, easement to include private property.
What is a private utility?
A private utility is owned and maintained by the property owner. Private utilities are not registered with Colorado 811. It is the excavator’s or property owners’ responsibility to have these utilities located at their own expense.
Common examples of private utilities include:
Sprinkler or irrigation systems
Electric running to a detached garage or shop
Lines connected to a propane tank or septic system
Gas lines under for grills and outdoor fire pits
Electric dog fence
Less common examples of private utilities:
Water – Customer owns the water line from the meter, property line or stop box to the building.
Sewer – Customer owns the sewer laterals from the tap at the sewer main into the structure, or from the property line into the home depending upon region.
Gas – Customer owns all the gas pipe after the meter.
Electric – Customer owns all the electric wires after the meter
Phone and Cable – Customer owns the service wire(s) from the backside of the protector or demarcation point.
It’s a common misconception that Colorado 811 marks all utility lines, including private utilities—but this isn’t the case. Colorado 811 serves as the communication link between you and public utility companies, which will mark their lines on your property.
For private utility lines, such as those for sprinkler systems, invisible fences, or gas lines to a backyard grill, you’ll need to contact a private utility locating company. To find one near you, visit this page.
Remember, locating all utility lines—both public and private—is essential to digging safely.
Tips for working around private utilities:
Keep in mind that public and private utilities are likely in your dig area.
Contact 811 before digging to request that the utility companies mark your public utilities.
Leave room in your budget for a private locate to be performed, this cost can vary.
Document the private locate markings with photos.
