Here when something is buried, a beautiful colored warning grid is put a little bit upper to warn the digger there's something behind. Yellow for gas, Red for electricity, blue for water, green for telecoms. It didn't stop backhoe operators to sever fibre cablers in the neighbourhood every year three years in a row. Last time they severed 72 fibre cables which were buried 1.2m deep.
I'm not sure having a map with everything indicated would help lot, when anybody in public works don't give a damn.
