What is the KWB?
• Foundation of KWB as non profit research network
organisation in Berlin in 2001
• Partial privatisation contract of Berliner
Wasserbetriebe – agreement on financial support for
the Berlin water research community by Veolia Water
www.kompetenz-wasser.de
Aims of KWB
•
Promotion of research and development in
Water resource management and
technology
– Sustainable water management
– Groundwater management
– Water and wastewater technology
www.kompetenz-wasser.de
Mission and activities
• Initiation, preparation and
realisation of research projects
• Exploitation of know-how
• Network management, public
relations
• International conferences and
symposia, training

Why water quality modelling?
• Surface water for
drinking water supply
• If there is any pollution
the water has to be
treated!
– Eutrophication
– Trace contaminants etc.
www.kompetenz-wasser.de
Why water quality modelling?
• EU Water framework • Global change:
directive:
– higher temperature,
– Quality aspects
– Origin of nutrients
www.kompetenz-wasser.de
– Higher/ lower nutrients
entry,
– more/ less storm events
Why water quality modelling?
• EU Water framework • Global change:
directive:
– higher temperature,
– Quality aspects
– Origin of nutrients
•The water supplier
needs to know:
–What has to be
expected?
–Which measures are
necessary to handle
the problem?
www.kompetenz-wasser.de
– Higher/ lower nutrients
entry,
– more/ less storm events
Aquisafe project
• Mitigation of contaminants
in rural/semi rural
environments
• Design and operation of
mitigation zones at the
UBA’s experimental field
• Identification of the most
effective place to establish
mitigation zones
www.kompetenz-wasser.de
CYLIN project
• Cyanobacterium (blue algae)
Cylindrospermopsis raciborskii of
tropical origin
• Occurrences in lakes of the Berlin
area
• Production of the cellular toxin
Cylindrospermopsin (CYN)
• Risk for bathing waters and also
for drinking water quality

Conclusion
Why water quality modelling?
• Assessing the impacts of climate change
• Achieving the Water framework directive
• Supporting management options
…regarding the water supply of Berlin!
