IWR supervised the pump replacement at pumping station Dörnberg. In this context, the delivery pumps for elevated tank Weimar were redimensioned on behalf of WBV Dörnberg, purchasing was organised, and technical support was provided for the 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.
