Over here in the UK, all cable / utilities companies have to bury their pipes etc at least 4 feet below the surface. That helps with these kind of things. Once, i worked as a commercial kitchen engineer with my father, and we'd got a job to install a full kitchen counter in a ground floor office. the job went well, we got all the counters installed, wired up and plumbed. So, one of the last things to do was to dig a trench to the nearest manhole for the drain pipework. So, there's me, happily pounding away with a pnumatic drill, when there's a 'Clunk', the drill drops about 2 inches, and water starts bubbling up around my feet... On removal of the drill, we were presented with a very pretty fountain, spouting from where it shouldn't!! As it turned out, i'd gone straight through a 2 inch pressurised fire main. So, we found out where the stopcock was, went and turned it off, cleared some muck & dirt from around the pipe, while my old man went to get some equipment to patch it all up. Once he returned, we chopped out the pierced piece, but we couldn't actually fix it, due to some leakage through the stopcock. One of the ways to sort that out, is to re-open the stopcock to it's fullest extent, which will usually clear whatever blockage is holding it slightly open. So, off i go, to perform this task, but what did i see when i returned? My father, standing there, dripping wet, having been clearing a little more dirt when the water came rushing back through the pipe, hit the angled wall of the trench and blasted up into his face! Heh! Bad luck pops!
