Know what's below! Diggers Hotline is a free service that helps keep Wisconsin families safe. Even small and simple digging projects can result in hitting buried electric, natural gas or internet lines in your yard. Knocking out your internet is bad, but coming into contact with an electric line is even worse. Contact Diggers Hotline at least three working days before your project, and we'll send the utilities to your location so they can mark where buried lines are. That way you can complete your project safely. Contact Diggers Hotline by dialing 811 from any phone in Wisconsin or reach us online at www.diggershotline.com
