Installing grounding rods...without hitting something critical?
Yes: call Dig-Safe , assuming you're in the USA.  The number is 811 , at least in the states I checked very briefly.

That will take care of gas &amp; electric and I believe water lines.  Tracing the sewer line, if not covered by Dig-Safe, should be pretty easy as it's almost always a straight run from wherever the pipe leaves your house to the street.
