Within two working days of your call to CBYD, a representative from each affected member utility company (not a CBYD staff person) will mark the location of their underground facilities with paint and/or flags at the excavation site. Make sure that your property is accessible. The utilities will only identify the facilities that they own or operate, not privately installed lines or facilities.
The One-Call System will not mark private or non-member utilities. The utility locating companies notified by your state One-Call system 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 One-Call locators. Other buried utilities that generally are not marked by One-Call include but are not limited to: sewer lines, private lighting, sprinklers, fire mains, secondary electric lines to detached garages, and septic lines.
