One of the aims of the cooperation is to gain a structured understanding of the replacement task of the three assets (bridges, dams and sewerage pumping stations) of the Scheldestromen Water Board. The aim is to use long-term planning to obtain a look-through for the next 30 years until 2050. To this end, a management and maintenance strategy should be developed, based as much as possible on data. This insight includes not only the maintenance and replacement task, but also its costs.
