Pennsylvania is under the 2009 ICC codes which reference the 2007 edition of NFPA 13R. I do not see a reference in that standard for any regulations or requirements for the underground fire service piping. It does not even reference NFPA 13 or NFPA 20 for the installation. Are there no requirements or am I missing something?

It typically requires a larger than usual water service. I believe you have to add 5 GPM or so for domestic water to the calculated sprinkler flow when you have a combined service.
