摘要： Methods and systems for installation of a liner inside a conduit (e.g., water pipe) to transport a fluid (e.g., potable water) to rehabilitate the conduit, in which the liner can be installed, and thus the conduit can be rehabilitated, more efficiently, including, for example, by further reducing an extent of digging that may have to be done, by testing more readily (e.g., pressure-testing for watertightness or other fluid-tightness once installed), and/or by adapting to a cross-sectional size of the conduit. Also, the liner may be thinner, interact better (e.g., less) with the fluid flowing through the conduit, and/or be otherwise designed to enhance its use and performance.
