Call Before You Dig

Whether you're planning construction, gardening, landscaping, fencing or any type of digging around your home, you must call Wisconsin’s Diggers Hotline to locate buried electric, natural gas, telephone or utility lines.

Coming in contact with utility lines can be extremely dangerous or fatal. Repairs to damaged lines can be costly.

Contact Diggers Hotline by phone or online at least three working days prior to the start of digging.

Some lines on your property may not be utility-owned. These are considered private facilities. You are responsible for these private utility lines. Utilities will usually not mark these lines. Private lines include those running from the meter pedestal to a house, a power line to a garage, gas lines to a grill or pool heater, or LP lines.
