New Gas & Water

Hi I'm looking for some information on installing some underground piping for a granny house we built in the backyard. I have to install the gas line, water line and electrical and I have one trench. Does anyone know wher I can get a diagram or information on the depth of each utility and if they can be ran together?




Thanks
Chuck

I'd say your first stop should be your local code enforcement agency. They are the ones that have to sign off on this and are the ones you have to please.
