I have a smaller 22 pads park in central Georgia that was built in the 1950s. The park has old galvanized pipe ‘buried’ maybe a few inches deep. How crazy would I be to pick up a metal detector for mapping these lines? Sounds like a creative/cheaper initial solution, but I’ve never used a metal detector and don’t know what to expect.
Water lines can be very shallow when there’s no real frost line to worry about.
