# TrenchlessSewer.ca > The trenchless sewer atlas — every method that renews or installs pipe without a trench, how it works, where it fits, and what it leaves behind. TrenchlessSewer.ca is part of the HAUSE Sewer network — an independent Canadian information and service-request network (not a contractor). Contact: sewers@hause.ca, 403-679-3100. Trenchless sewer work renews, replaces or installs buried pipe from a few access points instead of a continuous trench. Some methods line the old pipe (cured-in-place lining, slip lining, close-fit liners, coatings), some break or grind it out and pull in a new one (bursting, splitting, reaming), and some bore a brand-new path (directional drilling, auger boring, pipe ramming, microtunnelling). ## Guides ### Basics -
