Major secondary water leak

Monday started this week off with a wish we didn't work here. We developed a water leak between the shower rooms and Hopi somewhere. Sam & Jeff lined up from the shut off valve in the East parking lot to area where the leak was and where the pipe enters the building. (shower rooms) The hole was dug just behind where you see Sam. Have you guested it yet? We thought it did a turn where you see the hole and headed for the shutoff over in the East parking lot. NO pipe. Jeff & Sam jackhammered all the sawed concrete out to the building. Galvanized pipe with about quarter inch of rust and NO leak. Some where between the two. Under the mens side of the shower room, under the breezeway to the mail boxes, under the recycle, under the compactor? Who wants to dig up all that? You guested the answer to this one. NOT Sam & Jeff. It's now Tuesday after 5PM, everyone is long gone and we will be digging holes tomorrow. More on this situation tomorrow.
