811 is the national call-before-you-dig phone number. Anyone who plans to dig on their property should call 811 or go to their state’s 811 center website a few business days before digging to request that the approximate location of buried utilities be marked with paint or flags. This helps to ensure you won’t unintentionally hit an underground utility line.
Underground gas, electric, communications, water and sewer lines get damaged every 3 minutes from digging mishaps. People usually say they didn't call because they thought they knew where the lines were or they didn't think they were digging deep enough to cause a problem.
According to the Common Ground Alliance (CGA), "There are more than 100 billion feet of underground utilities in the United States. That figure equates to more than one football field.s length (105 yards) of buried utilities for every man, woman and child in the U.S."
The 811 service protects you and your community. Hitting a buried line while digging can disrupt utility service, cost money to repair, and even cause serious injury or death.
