How to Locate Utility Lines on Your Own

Electromagnetic utility locating is the most popular method for locating private utilities. The locating equipment generates an electromagnetic radio frequency, which, when applied to the ground, detects underground utilities containing conductive material on its receiver. 

This method is accurate and is frequently used to detect gas, telephone, cable tv, electric,  sewage, water, and irrigation lines.

Public and private utility locators employ high-tech equipment, and those employees have gone through extensive training to pinpoint the exact position of your underground utilities. This equipment is not accessible at your neighborhood hardware shop.

How to Locate Utility Lines on Your Own

As a result, while everything is possible, it is impractical for individual property owners to locate and mark buried utilities.

One method for determining the general location of a utility line is to locate its start and end points and then draw a mental line between them.

 This is a dangerous and unrecommended option. If the line is installed with bends to avoid obstructions, you won’t be able to establish the exact shape of the pipeline.

If you live in the United States, just call 811 before you start digging.

How Can I Dig Safely Around Gas Lines?

First, call 811. (In the USA only )

The Federal Communications Commission’s nationwide utility location hotline number is 811.

Before digging, call this number or go to your state’s 811 websites to receive a utility line finder. The center will dispatch a utility finder to locate and label underground pipes so that you do not dig into them.

If you have a contractor digging on your land, request that they be extra cautious and use color marks (yellow is for gas) or flags. The contractor should ensure that all workers stay outside the indicated lines.

If you must dig within 4 feet of markers, cautiously expose underground gas lines with hand equipment (such as a shovel with a wooden handle). Only once you have positively determined the position of the underground gas line can you employ power equipment to complete the excavation.

So, if you find yellow flags or inscriptions painted on the ground, please leave them alone! They are placed to indicate the position of underground gas lines. These utility locator markings keep you safe while preventing damage to underground lines.
