More help needed with pipe question?

Previously I asked who is responsible for the pipe from the water main to the house which runs from the middle of the road to the basement. Some of you say the city owns up to and including the meter. In my case the meter is in the basement; they read it electronically from outside. The pipe runs through the yard to the outside shut off valve at the property line. From there it runs under the sidewalk to the main in the street. The city says I own it all the way to the main, which would include my paying to open up the road and hire police to direct traffic if the leak is under the street. I contend they own the line from the main to the property line.
