As spring arrives, so does one of the busiest seasons for home improvement and landscaping projects. From planting trees to installing irrigation systems, millions of Americans are heading outdoors to break ground. But what many don’t realize is that some of the most important work happens before the first shovel hits the dirt.
April marks National Safe Digging Month, and Southwest Gas is using this time to remind homeowners and professionals alike of one critical step: contacting 811 before digging.
A recent national survey underscores the urgency. Nearly three in four homeowners plan to take on a digging project this spring—representing roughly 60 million households. Yet more than 10 million of those projects may begin without a call to 811, increasing the risk of striking underground utility lines.
For homeowners, the takeaway is simple: No matter how small the project may seem, digging without knowing what’s below the surface can lead to serious consequences. Utility lines are often buried just inches beneath the surface, and accidental damage can result in costly repairs, service disruptions or even dangerous situations.
Fortunately, there’s an easy, free solution. By calling 811 or submitting a request online at call811.com a few days before starting any project, underground utility lines will be professionally marked—helping you dig safely and with confidence.
Across Southwest Gas’ service territories, the need for safe digging practices are especially important. In Arizona, rapid population growth and ongoing housing expansion are causing widespread construction activity. In Nevada, continuous development and large-scale commercial construction further increase the risk of accidental dig-ins. And in California’s mountain and desert communities, seasonal construction and weather-related projects make calling 811 before any digging project a critical safeguard.
With these regional factors in mind, the Southwest Gas damage prevention teams work year-round with contractors, homebuilders, landscapers and nurseries to reinforce safe digging practices across growing communities. Their collaboration helps extend awareness beyond individual homeowners and into the broader network of professionals shaping neighborhoods.
These free training courses are offered for excavators, plumbers, landscapers, DIYers and anyone planning to conduct underground work throughout the utility’s service territory. The training provides a comprehensive overview of state-specific excavation laws, outlines the steps for conducting a safe excavation, explains the process for requesting utility line markings and highlights critical emergency considerations before starting a project.

It’s also important to know how to recognize a natural gas leak. Signs may include a distinct sulfur-like odor similar to rotten eggs, a hissing or roaring sound, or blowing dirt and discolored vegetation near a pipeline.
If you hit a natural gas line or suspect a gas leak, leave the area immediately, and do not attempt to inspect the leak or repair the damage yourself. Avoid any actions that could create a spark, including using a lighter, operating an automatic garage door, or turning electrical switches on or off. Once you are a safe distance away, call 911 and then notify Southwest Gas at 877‑860‑6020. Remain clear of the area until emergency responders and utility professionals confirm it is safe to return.
With more projects underway than ever, safe digging isn’t just a recommendation—it’s a shared responsibility.
Before starting your next outdoor project, take the extra step that protects your home, your neighbors, and your community: contact 811.
