  • Red: Electric lines
  • Yellow: Gas lines

    Danny says, “It’s hard to say, Bill. It could be a cable TV line or an old ‘invisible fence’ for dogs — but it’s really hard to be able to tell you exactly what it is.
    “Yellow wires can connect to many things, so it may even be hard to determine the source if I was standing there looking at it. It’s just almost impossible.
    Good luck with this!”

    I’m digging a trench around my carport because the next door neighbor decided to punt his house gutter runoff right at my carport and because I just purchased this home I noticed that my carport concrete slab is breaking because the water is causing the dirt to settle. I find two bare yellow wires going threw the concrete slab and onto his property. Let me state that our houses are close together. What are these wires anyway?

    Black Hills Energy and USIC (colorado), will not mark gas lines on homeowner (private)property. You must call and pay a private company for locate service

    Hi, Wayne!
    The safest option, which we recommend, is to contact 811 to locate these lines in your home’s yard.
    Thanks for your question.

    i bought my home 2 years ago. built in 1950 on hilly, 2 1/2 acres. how do i find the sewer and water lines.
    is there a detector like a metal detector?
    does the city have a reliable ‘map’?
    how deep are these lines typically?

    Greg the reason that water utility will NOT locate on your property is that after the water meter box (your service) is yours, the reason gas,phone or electric will locate on your property is that the utility responsible to the meter which runs on private property it is very uncommon for a wmb on private property, let’s say for an example you have a water leak past the meter and your a do it yourself incompetent renter you hook up a garden hose from the box to the house how can a utility company located it, they can’t and wont

    People s/b aware that water utility companies will not locate and mark water lines on your property. They will only locate and mark where service enters your meter near curb or street. They claim it’s not their responsibility and do not have capability to locate and will not come on private property. I have had other utilities locate and mark location on my property: electric, telephone, cable TV.
