Call Before You Dig

Please call 811 48 hours in advance.

Whether you are a contractor working on a site or a homeowner working around your own home, please note: Digging can be dangerous if you don't check first for underground wiring or cable. Underground wires could be power, telephone or cable television. Or there could be other underground utilities such as natural gas lines, water or sewers. Learn more about Call Before You Dig.

Never dig around your home or business without first calling this toll-free number for "Call Before You Dig" (CBYD) in Connecticut: 811. This statewide clearing house will contact member utilities to come to the site and mark where the underground utilities are located. In most of our service territory, we've contracted with a company called OnTarget Locating Services. They will respond to calls made to CBYD for marking CL&P underground lines. Connecticut law requires you to call at least two full working days, excluding weekends and holidays, before digging.
