In mid-2016, IWR GmbH was asked by Wasserbehandlungs- und Abwasserbehandlungswerke Zeulenroda to create an operation manual for wastewater treatment plant Zeulenroda. The goal is to compile comprehensible and clear instructions for the running of the facility. The operation manual will contain descriptions of routine tasks as well as instructions for extraordinary operating situations and the necessary rules for occupational safety. We are looking forward to the cooperation.
