The original bar screen intake and tunnel system were prone to blockage from gravel filled glacial melt water, to the extent that the scheme was almost abandoned. **Solution** The plant has been back up to full power since the installation of the Aquashear Coanda screens. The Type-A screens were installed in two back-to-back rows with a settling chamber underneath, giving a total flow rate of 2,660 l/s. The novel layout was designed and implemented by our Swiss partners Andaco, who have been responsible for more than 50 Aquashear installations in Alpine Europe.
