Sewer lines across Oklahoma
Prairie towns were plumbed in clay and, in the older districts, in cast iron that has now been underground for most of a century. The soils are deep, heavy and slow-draining, and the pipes were laid in long straight runs that have slowly sagged between their joints.
Wet springs saturate the clay subsoil and dry summers shrink it, so the ground moves twice a year. Street trees and hedgerows planted for shade send roots straight at the moisture in a leaking joint. Bellies and root masses are the common finding on the camera.
A belly cannot be lined out; the low spot holds water either way. Those sections are burst and relaid at grade. Joints with roots on an otherwise sound line are jetted, cut and lined as a single jointless pipe that gives the roots nothing to hold.
Pick a city above for the local picture, or read why replacement without a trench is usually the cheaper job once the driveway, the sidewalk and the street permit are counted.
