Are you planning an outdoor project that involves digging? Whether you’re a homeowner or a contractor, the simple act of digging can become a major safety risk if you don’t know what’s buried beneath the surface. To prevent accidental damage to underground utility lines and avoid potential injury or costly repairs, you must call 811 before you begin any excavation.
This service is a free, nationwide program that helps you identify and mark the locations of underground utility lines.
When Should You Call 811?
You are responsible for calling 811 prior to any construction or project that requires digging, no matter how big or small. Common examples include:
- Installing a new fence
- Planting trees or shrubs
- Building a deck or patio
- Installing a mailbox post
- Undertaking watershed projects or tilling operations
If your project involves breaking ground, it’s always safer to make the call.
The 811 Process: Call Early
Once you call 811, your request is sent to the local utility companies. We, along with other utilities, have two business days (not including weekends or holidays) to respond to a request to mark our lines.
This is why it’s crucial to call early! By giving us adequate time to respond, you can ensure that all underground lines are properly marked. This simple step can prevent you from accidentally cutting unmarked lines, which can lead to service outages, dangerous situations, and additional charges for repairs.
