Statewide depths can differ
Weather patterns in various states mean that recommended water line depths may be different depending on where you live. In Indiana, for example, Lake County in the northern part of the state near Chicago requires a 60-inch depth, while the water lines in southern counties located closer to Kentucky may be 36 inches deep.
Midwestern depth considerations
