Pipeline Safety: Know What’s Below

One of the leading causes of damage to underground gas pipelines happens during minor household and yard projects, like planting a hedge, installing a mailbox, or digging a trench for a sprinkler system. No matter how small, even a slight gouge, scrape, or minor dent in a gas pipeline could eventually result in a rupture or leak. There’s an easy way to avoid damage to underground gas or utility lines: make sure to call 811 before you dig. 

At least five days before the first shovel hits the ground, homeowners and contractors are encouraged to call the Hawai’i One Call Center at 811. You will need to know the address of where you plan to dig, including the nearest cross streets, as well as the type of project you’re completing. The Hawaiʻi One Call Center will contact all local utilities to mark or identify the location of underground utilities, at no cost to callers.

Gas is a safe, reliable, and efficient source of energy. On O‘ahu, Synthetic Natural Gas (SNG) is blended with renewable natural gas (RNG) and up to 15% zero-carbon-emissions hydrogen and transported to Hawai‘i Gas utility customers through 1,000 miles of underground distribution pipelines. Hawai‘i Gas also delivers propane to utility and non-utility customers on every island, including propane distribution locations. Utility customers receive propane gas through underground distribution pipelines. 

The wellbeing of our customers, community and employees is a top priority at Hawaiʻi Gas, and safety is everyone’s responsibility. It’s important to know what’s below—always call 811 before you dig. For more information about pipeline safety, visit hawaiigas.com.
