In 2016, we were given the opportunity to create the operation manual for wastewater treatment plant Zeulenroda, and now we are happy to report that our cooperation with WAZ Zeulenroda will continue in 2017. Together with their great wastewater treatment team we are creating the operating manuals for the wastewater treatment plants Auma, Triebes, Langenwetzendorf, and Hohenleuben. Today we visited all of the facilities, took photographs and received 53 kg of files to sift through. On this basis, we hope to develop operation manuals that will be much more than mere dust collectors on a shelf.
