811 doesn't mark everything...found out the hard way. The utility has to sign on with 811 before they are listed.

We did a 2k foot trench for a camera install on a large property with 2 water meters on the property, and the water company was not notified. Of course we hit the water line going to the home owners house. Called 811 and they said the the East Daviess County Water is not part of the 811 location services. WTF they could have said something.
