How far does the water line run before it reaches a house in 85338?
Further than most people expect. 85338 is about 76 square miles of ground. So the private line from the meter to the house is often a long buried run.
Everything on the house side of the meter belongs to the owner. Across 76 square miles a loss can be entirely invisible. Sometimes a patch of ground stays greener than the rest, and sometimes nothing.
The line gets found before the leak does. Put a signal on the line, walk its real route, then listen along it. See underground leak detection and water main leak detection.
