We maintain a network of sewage pipes around 350 kilometers in length, together with the pump stations. This often involves the sewage workers inspecting underground systems. In such cases, they carry a mobile gas detector and a self-rescuer. A colleague secures them with a cord. I know how important such safety precautions are – to protect us from sewer gases and other hazardous substances that we may encounter in the sewer network. At the vocational college we also learn about the physical and chemical background to our work. The job is extremely diverse and technically demanding. This is also evident in our “helicopter” – an orange and red four-axle truck designed specifically for sewer work. It is named after a helicopter because its jib can spin on its own axis with the flushing hose. We don’t just carry out inspections, maintenance, and cleaning work underground, but also take care of natural sites, where surface water collects and drains off. The thing I find interesting about the sewer network in both of our cities is the fact that you can see how they have developed over the years.
