What is the Difference Between a Public Utility Locate and a Private Utility Locate? Public Utilities (Public Utility Locate) are the electric, gas, phone/cable, water and sewer lines that are brought in to a point by agencies such as Verizon, Con-Edison, JCP&L, and Cablevision and where they determine their responsibility ends (typically at the meter).
Color Coding Utility color codes are used for identifying existing underground utilities in construction areas with the intent of protecting them from damage during excavation. Public utility systems are often run underground; some by the very nature of their function, others for convenience or aesthetics. Before digging, local governments often require that the underground systems’ locations be denoted and approved, if it is to be in the public right-of-way.
What Is Utility Locating? Utility Locating is the process of identifying and labeling public utility mains which are underground. These mains may include lines for telephones, electricity distribution, natural gas, cable television, fiber optics, traffic lights, street lights, storm drains, water mains, and wastewater pipes. In some locations, major oil and gas pipelines, national defense communication lines, mass transit, rail and road tunnels also compete for space underground. Because of the many different types of materials that go into manufacturing each of these different types of underground lines, different utility detection and location methods must be used. For metal pipes and cables, this is often done with electromagnetic locating equipment consisting of a transmitter and a receiver. For other types of pipe, such as plastic or concrete, other types of radiolocation or modern ground-penetrating radar must be used.
