In July 2018, the two new digesters of Wastewater Treatment Plant Würzburg were inaugurated. They are considered an art installation when illuminated. The concrete buildings with the façade insulation have already been implemented since spring-time and now also the membrane shells are on the digesters. Dr.-Ing. Anke Durth is the responsible project manager for the construction of the two new digesters. "They replace the 40-year-old digesters of the wastewater treatment plant, the capacity of which is no longer sufficient to treat the entire amount of sewage sludge. With the new digesters, the amount of sludge to be disposed of is reduced by one-third and power production is tripled", explains Anke Durth, who has been working for 15 years in the expert committee KEK-1 of the DWA-Board Committee for Recycling/Energy/ Sewage Sludge. The water and sewerage company of the city of Würzburg commissioned DAHLEM with the planning for the new construction of the digesters and several operations buildings, in which the facilities for gas treatment, gas utilization, co-substrate acceptance, etc. are housed.The façade design of the digesters and the operations buildings is the result of an architectural competition. The towers are covered with membrane layers of different shapes, so that two similar but not identical sculptures have been created.
Many municipalities have experienced how massive the damage caused by heavy rain can be in recent years. Targeted flood prevention against are heavy rainfall and flash floods is becoming increasingly important in this context. It represents a major challenge for the municipalities and is closely linked to the municipal adaptation to climate change. The establishment and implementation of coordinated rain risk management is on the one hand a new task. On the other hand, a flood preparedness system coordinated by the various specialist departments increases the complexity of planning and administrative processes and raises questions that are still unanswered. The project "Municipal Flood Prevention - Planners in Dialogue" of the German Institute for Urbanism (DIfU) in cooperation with DAHLEM and numerous experts from the various administrative departments of 15 German cities examined how flood prevention can be achieved within a network of municipalities. The project was funded by the German Federal Environmental Foundation (DBU) in the course of two years. The special feature of the project lies in the fact that the municipalities were represented in each case by the affected department (urban planning, environment, landscaping, roads, municipal water supply and sewerage, disaster control). In eight daily workshops, case studies were developed, where typical obstacles and problems but also possible solutions and success factors lie. Based on the practical experience of the municipalities, recommendations and solutions for administrative work within a municipality were summarized in a brochure. It serves as an aid to municipalities that want to get more involved in heavy rain protection and answers questions (FAQ) on the topics of organization, law, financing, planning/implementation and operation maintenance.
