One-Call and private utilities
Pennsylvania One Call System, Inc.

800-242-1776 | 412-464-7100
Our purpose is to prevent damage to underground facilities. To promote safety, we provide an efficient and effective communications network among project owners, designers, excavators, and facility owners.
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.
