The existing bar screen in the pumping station of La Roche-de-Glun (Department Drôme (26) in the Auvergne-Rhône-Alpes region) had to be replaced by a modern and efficient filtration technology. The pumping station conveys water from the river Rhone, which is required for agricultural irrigation in one of the most renown plantations for apricots and wine in Europe.

Solution
Successful replacement of the existing bar screen of a competitor by the Geiger® MultDisc® Travelling Water Screen during a short time-window prior to the irrigation season. After the ceiling opening of the existing structure was enlarged and the lateral guides were doweled on, the complete machine could be lifted into the structure in one piece for a fast commissioning.
