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.

District One Call is your partner when it comes to safe digging! Having a variety of utility services could mean you have lines and pipes running underground, do you know where they are? If you plan on any type of excavation or digging on your property, District One Call can help. District One Call is a one-call notification center that informs subscribing facility/utility owners of proposed excavation. So, if you plan to install a new mailbox or plant a garden, contact the call center at least (48) business hours prior to your intended digging. We will notify our member facility/utility owners of your proposed plans to dig; they in turn will locate (mark your dig site or verify the site is clear) before you put that shovel in the ground.
