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. A more rigid shiplap joint is formed between mating conduits by means of cantilever legs extending from the end of a conduit, forming a female pocket like space for the mating unit, and by having a continuous web on the peak corrugation adjacent the end. A sub-arch at the top of an overlapped valley end, to enable connection of a pipe to the conduit, is spaced apart from the web of the adjacent peak corrugation; there are multiple legs on either side of the sub-arch, with the sub-arch connected by webs to the adjacent legs, and by other webs to the peak corrugation.
