S&T Project 23012: Investigating Innovative Exposed Lining Systems
High-Density Polyethylene (HDPE) liners have long been the standard for exposed containment applications due to their proven durability in both laboratory and field conditions. However, emerging liner technologies have not been thoroughly evaluated in long-term, real-world settings. This study aimed to compare the performance of six liner materials—including HDPE, EPDM alloy, polyurea-impregnated geotextile, bituminous geomembrane, reinforced polyethylene, and a concrete composite—through laboratory durability testing and field trials in Oregon’s Klamath Irrigation District (KID). The project involved coordinated efforts among the Technical Service Center, KID, the Klamath Basin Area Office, and liner manufacturers. Preparations included initial seepage measurements, acquisition of testing materials, and procurement of specialized laboratory equipment. Despite substantial progress, the project was suspended due to unexpected delays in equipment delivery and the late-stage initiation of a complex environmental compliance review, which exceeded available time and budget. Although the research was not completed, key lessons were documented, emphasizing the need to account for regulatory timelines and environmental compliance in early planning stages. Future efforts will seek renewed funding to continue evaluating alternative liner materials.
