Call Before You Dig
Before starting any digging project in South Dakota, it's essential to call 811 at least 48 hours in advance to have underground utilities marked. This free service, officially known as South Dakota One Call, helps prevent dangerous and costly accidents by identifying the location of buried gas, electric, water, sewer, telecommunications, and cable lines. Hitting an underground utility can result in serious injuries, service outages affecting entire neighborhoods, expensive repairs, and potential fines. The law requires calling 811 before digging, whether you're installing a fence, planting trees, or undertaking major construction.
Simply dial 811 or submit a request online
