TrinkXtrem: Adaptation strategies of public drinking water supply to extreme events

Sub-project 8 funded by the Federal Ministry of Education and Research (BMBF)


Extreme hydrological events are an increasing challenge for public drinking water supply. Against the background of climate projections up to 2100, there is a considerable pressure to act to ensure drinking water supply. Research is needed for example to better predict extreme events with regard to their impact on available raw water resources. Using an existing numerical groundwater model as an example, its predicitvity shall be improved by data analysis, calibration and data assimilation. In the future, real measured values shall be steadily assimilated into the model in order to adapt it continuously. The aim is, that the numerical groundwater model represents the reality more exactly and therefore a improved basis for the management of the raw water resource results.

The Consortium "TrinkXtrem"

In the BMBF research project TrinkXtrem, water supply companies from different regions of Germany are cooperating with research institutions to adapt the management of drinking water supplies in Germany to extreme climatic events such as droughts or heavy rainfall. The aim is to respond to special hydrological situations in a scientifically sound and forward-looking manner. Precautionary concepts as well as methodological and digital tools are being developed. These will then be implemented in representative model regions. The project consortium consists of ten partners and five associated partners.
