Especially in the summer months, odour nuisance caused by hydrogen sulphide (H2S) occurred in Berlin-Köpenick. At the beginning of a 1.8-kilometre-long pressure pipeline is a pumping station that pumps the collected wastewater through the old town. Biogenic corrosion in the sewer causes extremely high remediation costs for the operator. Moreover, the stench is not only unpleasant for the citizens, but also harmful to their health.
H2S measuring devices have already been in use for some time. In the past, however, an employee had to drive to the old town every week, open the sewage shaft and read out the measurement data. The measurement data was then analysed and the dosage adjusted accordingly. A lot of time passed.
