HDPE LINED WATER RESERVOIRS FOR POWER GENERATING STATIONS

摘要

An impervious High Density Polyethylene (HDPE) geomembranes have been successfully adopted as an alternative water barrier to conventional clay liners system of hydraulic reservoirs and ponds for few decades. With the ever-growing of population, the demand for more electric power capacity increases, hence bring to the need for more new high efficient generating stations and innovative methods of generating electricity from existing power plants. The HDPE geomembrane with outstanding mechanical properties and high durability provides a cost-effective solution as seepage control and leakage prevention to the reservoirs and dams. This paper highlights the manufacturing quality assurance and characteristic of the High Density Polyethylene (HDPE) geomembrane as waterproofing elements. Case studies on the application of HDPE geomembrane as an effective lining solution to the water reservoirs and dams for power generating stations are presented in this paper. Finally, discussion on the geomembrane installation and field quality assurance are also described in this paper.
