underground pipes
Subterranean water mains
Underground pipes are conduits buried beneath the surface for transporting water, sewage, gas, or other materials.
The phrase is literal and compositional—pipes that run underground—rather than a fixed expression.
Infrastructure discussions often reference underground pipes when addressing utilities, drainage, or aging municipal systems: The city is replacing underground pipes installed in the 1920s.
