Frastanz Hydro Intake Refurbishment, Austrian Alps

Client - Andaco gmbh

Project Overview

Austria hosts the largest Aquashear installation in the Alps, with screens retro-fitted to the existing intake of the E-Werke Frastanz hydro scheme. 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.


Coanda screen


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.
