PA One Call System, Inc. is a non-profit Pennsylvania corporation created to protect the underground facilities of members through communication with any person(s) planning to disturb the earth. This communication network receives and processes line location requests from Excavators, Contractors, Plumbers, Builders, Designers, and the general public; and disseminates this work location information to all members based on their service agreements.  PA One Call's goal is to prevent damage to underground facilities.
