anyone know where or how to find a septic tank? I've traced the line from the house 30" down in the ground out 10' to 20' all I've got is fox holes! I went out another 10' 15" down and no luck finding the tank. only the pipe . its a 1500 gal. tank . the septic plan is no good as it had only the " proposed house site and is not correct. I dug at 20' according to the plan and as mentioned only got the pipe again. [img]/forums/images/icons/mad.gif[/img]
