Water supply is heavily influenced by structural conditions, i.e. natural (e.g. geology, hydrology) and man-made (e.g. settlement and water user) characteristics. In actual benchmarking projects the relevance of these structural and regional differences is hardly taken into consideration. For this reason, a clustering process for comparable utilities has been developed which is based on identified structural conditions. The clustering process was verified and applied in a data assessment study with 45 German utilities. Source

A systematic risk management approach is an important management tool to assure a sustainable control of a high quality and security of drinking water supply. The article explains methods of risk identification and risk assessment following the German DVGW standard W 1001. Practical examples concerning the operation and maintenance in drinking water distribution networks show important issues of its implementation. Source
