In March 2019 Aqua Vision performed (ADCP) discharge measurements at pumping stations Liemers, Bevermeer, Grote Beek and Baakse Beek in the domain of Waterschap Rijn en IJssel. The measurements were carried out in order to determine the capacity of the four installations. The results were used by our client Tauw in combination with energy consumption and number of revolutions to determine the overall performance of the stations .
