April is National Safe Digging Month! Did you know that every eight minutes an underground utility line is damaged because someone decided to dig without first calling 811. This month reminds diggers the importance of calling 811 before all outdoor digging projects. Striking a single line can cause injury, repair costs, fines and inconvenient outages. Every digging project, no matter how large or small, warrants a call to 811. Installing a mailbox, building a deck and planting a tree or garden are all examples of digging projects that should only begin a few days after a call to 811. When calling 811, homeowners and contractors are connected to the local call center, which notifies the appropriate utility companies of their intent to dig. Professional locators are then sent to the requested digging site to mark the approximate locations of underground lines with flags, paint or both. The depth of utility lines can vary for a number of reasons, such as erosion, previous digging projects and uneven surfaces. Utility lines need to be properly marked because even when digging only a few inches, the risk of striking an underground utility line still exists.
