The sewer network in the city has been undergoing renovation since June 2025. It is planned to complete this city-wide construction project with around 70 pipe liner renovations and around 70 partial repairs by June 30, 2026. The municipal drainage company and the contractor will inform the affected residents of the exact timeframe in good time by letter and leaflet.
Rarely major traffic disruptions
In order to ensure a smooth and speedy construction process and thus keep the restrictions for residents as low as possible, road areas will be closed in sections. There may therefore be traffic disruptions during the construction period and in the detour roads affected. As a rule, however, these will be short-lived. The work can often be carried out within five to ten hours per paving section. However, it should be noted that more extensive traffic safety measures are only necessary for the actual pipe liner rehabilitation (main work) and that this is associated with traffic restrictions.
What is trenchless sewer rehabilitation?
In contrast to a sewer replacement, for example, it involves several work steps. These include preparatory work, main work, follow-up work and acceptance inspection. These take place independently of each other (one after the other) and can be carried out one or two months apart. A single installation stage is not actually considered complete until the acceptance inspections have been completed and any subsequent remedial work has been carried out. As a rule, the preparatory and follow-up work rarely causes major traffic disruptions. This is because smaller vehicles are used.
