Storage Management and Flood Warning in Urban and non-urban Drainage based on Runoff Prediction
Dr.-Ing. Heiko Sieker, Dr.-Ing. Harald Sommer, Dipl.-Ing. Frauke Jakobs, Dr.-Ing. Zhengyue Jin
Intense rainfall events are a major cause of flooding problems in urban and non urban areas. They are due to increased sealing of areas resulting in high runoff volumes. Especially in urban areas and small catchments the time interval between rainfall event and flood peak can be very short.

Process Benchmarking in Drinking Waterworks in Germany
Dipl.-Volksw. Andreas Hein, Dr.-Ing. Wolf Merkel
The ‚Äúwater production process‚ÄĚ summarizing resources management, water catchment and treatment is a key process in the water supply chain. During 2005 to 2008 a new bottom-up approach was developed and tested, allowing a detailed performance (cost, quality, sustainability) analysis on the process level and accounting for differing water resources, treatment schemes and assets. During subsequent projects some additional functions of the IWA performance indicator model for water supply (Alegre et al., 2006 [1]) have been supplemented on the process level, e.g. processes in water networks.
Biofilms on aged Materials in Household Installation Systems
Dr. Gabriela Schaule, Dr. Simone Schulte, Prof. Dr. rer.nat. Hans-Curt Flemming
The causes of contamination originate in the water itself and on materials in contact with water. Drinking water is not sterile and does not have to be. Water treatment plants‚Äô strategy consists in removing the nutrients that bacteria feed on to produce ‚Äúbiostable‚ÄĚ drinking water. This allows in many cases chlorination to be avoided. But it is known that even biologically stable drinking water with very low nutrient content still contains micro-organisms. These micro-organisms can multiply themselves if they encounter nutrients.
Network Analysis with the KANEW Asset Management Framework
Ingo Kropp
In recent years several studies from DWA, AWWA, US-EPA and other international organizations have shown that utilities have to cope with increasing investment needs of their ageing infrastructure to guarantee good and reliable services for their customers also in the future.
