Document Description
The Robert A. Skinner Finished Water Reservoir (FWR) has a 16-acre Hypalon floating cover. Small tears were discovered in the cover during routine inspection and maintenance. The tears were caused by delamination, or separation between the multiple layers of the Hypalon cover material. Since delamination was not observed during any prior inspections, it appears to have occurred recently and relatively quickly. As an interim measure, Metropolitan has reinforced suspect areas to prevent further damage. Due to the importance of the FWR to Skinner plant operations, Metropolitan is proposing to proceed promptly with preliminary and final design of a replacement cover. The existing floating cover was constructed prior to implementation of recently updated California Department of Health Services (CDHS) guidelines for design and functionality of floating covers. Upgrades are required for the replacement floating cover to comply with the new guidelines, and approval of the design by CDHS is required.
