Climate change and extreme weather events call for new strategies

The prolonged periods of great heat and drought have led to limited availability of drinking water in some regions of Germany. The lower availability of groundwater and water from dams, rivers, streams or springs is offset by an increasing demand, for example, for cooling power plants and industrial facilities or for irrigating agricultural land and green spaces. Due to climate change, it can be assumed that the discrepancy between water supply and water demand will become even greater in the future, particularly at regional level. The current Newsletter No. 47 (in German) reports on projects in the TZW on the impacts of climate change on drinking water supply and the development of concepts to counteract the negative consequences. These include two projects under the KLIMOPASS programme and the Master Plan for Water Supply in Baden-Württemberg initiative. Other projects are investigating changes in the quality of water resources and the effects of increased temperatures in the pipeline network.

The newsletter also provides information on:

  • One substance, several sources - a new challenge for water supply and authorities
  • PSM pollution in the raw water resources of the drinking water supply
  • Antibiotic Resistance and Microbial Source Tracking at Lake Tai in China
  • Odour threshold value as part of hygiene testing according to KTW evaluation basis
  • Legionella in cold water
  • EU digitalisation project
