The IWR supervised the pump renewal Dörnberg pumping station. In this context, the delivery pumps to the Weimar elevated tank were redesigned for the Dörnberg water procurement association, purchasing was organized, and technical support was provided for installation. As a result, since September 2012, the energy needed to pump drinking water to elevated tank Weimar was reduced by 10%. We hope to continue implementing progressive technologies together with our clients, in order to reduce energy consumption and to organise water supply in a reliable and cost-efficient way.
