IWR has taken care of the dimensioning of the new pumps for elevated tank Weimar on behalf of Wasserbeschaffungsverband Dörnberg, and subsequently has organised the acquisition process and supervised their 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.
