On October 12th, 2022, the Prime Minister of Kosovo, Albin Kurti, officially inaugurated the new fully biological wastewater treatment plant of the municipality of Peja. The wastewater treatment plant was handed over on time and on budget by DAHLEM on a turnkey basis and has already been in operation for one year. The plant is operated by the regional water and wastewater company Hidrodrini. Together with the German and Swiss ambassadors as well as the mayor of Peja and many other guests, the completion of the wastewater treatment plant was celebrated. The entire project was financed mainly by KfW, in cooperation with Kosovo. Likewise, the Swiss State Secretariat SECO and the municipality made substantial contributions to the 23 million euro investment costs, which include not only the treatment plant but also an extension of the sewerage network. WWTP Peja offers a strong contribution to the environmental protection and health care for south-western Kosovo.

The KEYS research project, which began in 2017 under the leadership of ISAH Hannover, with the participation of DAHLEM and in cooperation with TSINGHUA University Beijing, has now been brought to a conclusion. Various German-Chinese cooperation projects for sustainable water management were developed for the national "Sponge City Concept" in China. In the period 2018-2020, DAHLEM collaborated on two sub-projects in the greater Beijing area, focusing on an implementation-oriented approach of sponge city concepts. Together with the ISAH and the Berlin Water Competence Centre in Germany, project experiences were transposed into an element catalogue showing needs-based solutions of the sponge city concept for the local metropolitan area. For China, the implementation of the sponge city approach is an important and recognised step to make cities fit for the future. Sponge City elements as a combinatorial overall concept help to mitigate urban heat island effects and flash floods, improve groundwater recharge and quality as well as the structural diversity of urban spaces. They basically follow the natural model and impress with their simplicity and efficiency.

The Video of the Stadtwerke Karlsruhe shows the future project of the watersupply treatment plant Mörscher Wald

[Translate to Englisch:] Das Video des Architekten Martin Willms zeigt den Baufortschritt des Wasserwerks

It has been completed: The new construction of the Mörscher Wald waterworks, for which the ground-breaking ceremony took place in November 2018. Commissioning is currently underway and the official inauguration will take place in July 2022. The new waterworks is equipped with state-of-the-art technology and now replaces the 70-year-old plant in the immediate vicinity on a directly adjacent plot of land. After commissioning of the new plant, the existing one will be completely dismantled. For species protection reasons, demolition will not take place until September 2022 and the area will be reforested. In future, the new waterworks will ensure the vital supply of potable water for the city of Karlsruhe and the surrounding communities. Calculations of the potable water demand until 2040 showed that, due to climate change and the predicted population growth, a capacity of 60,000 m³/d or 3,000 m³/h will have to be maintained in the future as the maximum capacity for raw water extraction and treatment. The architectural design of the building provides for a harmonious integration into the greenery. As a partner in a consortium, DAHLEM has been commissioned with the planning of the civil engineering works, the building interiors and the outdoor facilities. A BIM-oriented 3D model was created for the building design.

The focus of this year's IWASA symposium in the fight against floods is increasingly moving in the direction of heavy rain and flash flood events. In the past two decades, the formerly pure flood protection has evolved into flood risk management. Experts and the public focused on this development, accompanied by the requirements of the EU Flood Directive, in particular flood events on rivers, triggered by the flood events on the Rhine (1993 and 1995), Oder (1997) and Elbe (2002 and 2013). DAHLEM is represented with an information stand at the conference. You are welcome to discuss the high relevance of the topic, due to new requirements, with experienced colleagues from our Darmstadt office.

There were 6,283 running enthusiasts who finished the Essen 2022 corporate run in beautiful weather. This is already the 10th Essen corporate run for the DAHLEM running community. In glorious running weather, the Essen 2022 corporate run was on the agenda for over 8,800 registered participants on Wednesday, 22nd June. The runners covered a five-kilometre course, from Huyssenallee at the Philharmonie to the Tummelwiese at the Grugabad. And once again the motto was: “With each other - for each other”. A highly motivated DAHLEM team went to the start again. "Taking part and reaching the finishing line is our motto". From 7:00 p.m. the starting line was filled with running enthusiasts on Huyssenallee. The distance could be covered running or walking. It is not about the competition between the companies, here everyone comes together to enjoy the sporting event with a lot of fun and the highest level of commitment.

Since May 2021, DAHLEM has started supporting KUER.NRW as a specialist. KUER.NRW is a funding programme implemented by pro Ruhrgebiet e.V. and Business Angels Netzwerk Deutschland (BAND) on behalf of the Ministry of Environment, Agriculture, Nature and Consumer Protection of the State of NRW. KUER supports "green startups" in North Rhine-Westphalia, founders and startups having an innovative product, process or service idea with market potential in the KUER sectors of climate, environment, energy and resource conservation. Specially accredited KUER mentors, specialists, industry experts and angel investors accompany them through all phases of their startup - from idea generation and the preparation of the business plan to company creation, market launch and financing, tailored to their specific individual needs.

The rising number of extreme weather events increases the risk of flooding, also on company premises and in buildings. Rising costs and fees place an additional burden on companies. It is therefore worth investing in intelligent water management: How can stormwater be collected and used as process water? How can water be infiltrated instead of being discharged into the sewer system? A variety of often easy-to-implement measures prevent damage and save costs. These and other questions were discussed at an online cooperation event organized by Business Metropole Ruhr GmbH and the Emscher Association for Water Management/Lipper Association (Emschergenossenschaft/Lippeverband). Business Metropole Ruhr markets the Ruhr region as a business location and, among other things, supports companies with future-oriented, environmentally-friendly technologies. Professor Dr. Peter Höppe, former head of GEO Risks Research/Corporate Climate Centre Munich, opened the discussion round with his lecture "Too much and too little water - climate change aggravates the extremes", which was accompanied by representatives of the business community and local authorities and during which more than 100 live participants were able to ask questions to the speakers. Holger Ackermann, the responsible person  for water management from DAHLEM, was a participant in the four-person panel. In his view, climate adaptation measures are not an expression of ideology, but of foresight and common sense.
