Orange Grove, CA
EFI addressed the issue of existing covers leaking – many of which had been repaired several times over the years. Because biogas is used as boiler fuel, Sun-Maid’s facility required a gas tight cover to ensure economical plant operation. In order to minimize biogas production loss, EFI was able to compress the construction schedule.
The geomembrane work was completed on schedule, with a new cover fabricated on site before the existing cover was removed. The digester is operated at a constant level and the biogas is not stored under the cover for long periods of time.
