For this job, I rented leak detection services for Mr. Jason Lee. Approved the entire water main service despite normal frequency delineation in the unpaved area. I did not discover a leak on the water main service in the grass on either side of the driveway or in the flower bed at the location of the water main service penetration. I listened to the concrete upon the driveway and detected frequency Delineation indicative of a leak on the water main service right at halfway up the driveway. Leading me to believe that the leak is underneath the driveway at that point.
