ABSTRACT:
A conduit for dispersing or gathering liquids in the earth has an arch shape cross section and alternating peak and valley corrugations along its length, with cantilever legs extending from one end to interact with the mating portion of a like conduit. The legs, along with a shiplap joint having flange discontinuities for manufacturability, provide a superior rigid joint when the conduits are mated and buried beneath the earth and subjected to vertical loads.
