I’m looking into the technologies that are available for removing lead pipes without needing to dig a trench above the pipe. This site lists a number of ‘trenchless technologies’. Extraction of lead pipes is a special problem, because many technologies rely on being able to break up the old pipe and leave it in the soil, but this isn’t a desirable option for lead pipes.
This
site describes a technique where cables are run through the
existing pipe, the pipe is cut up into pieces, and the cable
is then used to pull the old pipe out and pull the new pipe in.
This site
further describes the Grundopull technology (cute name!).
