A water management system includes a series of corrugation couplers adapted for compressibly connecting and detaching liner sections end to end. Each corrugations coupler is included in successively formed corrugation segments. Each corrugation segment includes two adjacent corrugations, a leading corrugation, and a trailing corrugation. The leading corrugation is formed with a substantially triangular cross-section having a rounded apex (the "extended corrugation"); the trailing corrugation in a corrugation segment is formed with a substantially frustoconical cross-section having a height less than the height of the extended corrugation (the "shortened corrugation"). Also included is a connector for contributing to interconnecting liner sections end-to-end. A compressibly resilient gasket is included for contributing to sealing the liner sections.
