| 摘要： | The relining and cover replacement of the Lake Forest project incorporated many of the current best practices outlined in the American Water Works Association (AWWA) Manual M25, Flexible-Membrane Covers and Linings for Potable-Water Reservoirs. As the owner required a 30-year service life for the liner and cover, the material selection of the CSPE material with its 50-year proven record in potable water reservoir was an important choice. The project also incorporated an important weighted tensioned floating cover design, including strategically located custom troughs designed to manage the water service levels and center divider wall. Factory prefabrication of the materials and appurtenances was essential, ensuring high quality as well as reduced installation risk and costs. With the integration of a site-specific operation and maintenance program including regular planned inspections, all stakeholders involved are confident that the new Lake Forest reservoir liner and floating cover system will perform very well and achieve its expected 30-year service life. This project is another good example of engineered geosynthetic floating covers being used to protect our environment. |
