Wastewater networks are important assets—for local authorities, but also for many industrial enterprises. To ensure the functions of these investments for the future and to avoid environmental damage, there is a considerable need for maintenance and, where necessary, rehabilitation. The enormous cost pressure is precisely what drives innovation in this industry. For example, an increasing number of operators are switching from regular—in many cases unnecessary—sewer flushing to needs-based cleaning. The key, here, is continuous monitoring and condition assessment of the systems. The environmental technology industry offers solutions using, for example, advanced sensors, AI-based algorithms, virtual reality, and digital twins.
Trenchless rehabilitation techniques are at the forefront of damage repair. In many cases, the economic and ecological benefits outweigh the advantages of the cut-and-cover method.
