Southwest Gas Celebrates National Call 811 Day: One Call Protects Dig Projects

Data shows a decrease in damages with an increase in calls to 811

LAS VEGAS, Aug. 5, 2025 /PRNewswire/ -- On August 11, as part of National Call 811 Day, Southwest Gas is reminding everyone, from weekend DIYers planting a tree to seasoned contractors tackling major commercial projects, that calling 811 before digging is a simple and free step that safeguards lives, property, and vital utility services.

Every digging project, regardless of the size, requires contacting 811. By reaching out to 811 or visiting call811.com at least two working days before digging, utility-owned underground lines will be marked at no cost, helping prevent damage to natural gas, electric, water, and other essential services.

Proven Safety Results 
In 2024, Southwest Gas experienced a 15 percent drop in underground utility damage, thanks in part to a 10 percent rise in 811 requests. However, over a quarter of natural gas incidents still stemmed from digging without prior notice, underscoring the continued need for greater awareness and proactive measures.

Tips for Safe Digging 
Southwest Gas encourages anyone launching a digging project to follow these best practices to help keep projects safe:

• Hand dig carefully within two feet of newly marked lines
• Use blunt tools like rounded shovels to avoid puncturing lines
• Watch for soil changes or unexpected materials that may signal proximity to a utility line
• Verify line depth and location, don't rely on assumptions or old markings
