Pacific Gas and Electric Co. reports that Sunday, Aug. 11, is recognized as National 811 Day, to raise awareness of the importance of making a free call to 811 before any digging project, large or small. Whether a caller is a property owner or a contractor, calling 811 will help ensure that projects involving digging can be done safely while avoiding expensive repairs or fines due to damaging underground utility lines, said PG&E.
Underground utility lines can be buried at a shallow depth, sometimes only a few inches below the surface, said PG&E. They can be affected by any project that involves digging, including building or replacing a fence, planting or landscaping, and beginning construction work.
In PG&E’s service area, underground gas and electric lines have been damaged due to digging 573 times so far this year. In 58% of those cases, 811 wasn’t called. The percentage of residential customers striking lines while digging who didn’t call 811 is 89%. Making a free call to 811 can also save the caller money, said PG&E — damaging an underground line while digging leads to repair costs averaging $3,500.
“By making a fast and free call to 811, utility professionals will come to your home or job site and mark the location of underground lines so that you can dig safely and avoid expensive repairs,” said Joe Forline, PG&E senior vice president of gas operations. “Know what’s below before you start any size digging project, whether you are planting, landscaping or doing fence work and call 811 two days before you dig.”
When a call is placed to 811 and a request is made to have lines located and marked, a professional locator will come to the project site to mark the location of underground utility lines, including electric, water, telecom and sewer, free of charge. Knowing where underground lines are buried while digging — and following safe digging practices — will help keep everyone safe and connected to essential utility services, said PG&E.
Warmer weather months see an increase in digging projects and a corresponding increase in the number of strikes to underground lines that have not been marked ahead of time. Leading causes of damages to underground utility lines while digging include building or replacing a fence, gardening and landscaping, planting a tree or removing a stump, sewer and irrigation work and building a deck or patio.

PG&E reports that calling 811 is fast and free. Customers should call 811 a minimum of two business days before beginning any project that involves digging, no matter how large or small. Customers also can visit 811express.com to have underground utility lines marked for their project site.
Professional utility workers for all utilities (electric, water, sewer, telecommunications, etc.) will be dispatched to mark the location of all underground utility lines for the project site with flags, spray paint or both.

PG&E safe digging tips
When working on a project that requires digging, PG&E recommends the following tips:
- Mark project area in white: Identify the digging location by drawing a box around the area using white paint, white stakes, white flags, white chalk or even white baking flour.
- Call 811 or submit an online request a minimum of two working days before digging: Be prepared to provide the address and general location of the project, project start date and type of digging activity. PG&E and other utilities will identify underground facilities in the area for free. Requests can be submitted a maximum of 14 days prior to the start of the project.
- Dig safely: Use hand tools when digging within 24 inches of the outside edge of underground lines. Leave utility flags, stakes or paint marks in place until the project is finished. Backfill and compact the soil.
