To estimate the risk of viruses in raw water of drinking water reservoirs six drinking water reservoirs in Germany were examined for viruses and microbiological indicator parameters. The causes of few positive evidence were several interacting factors. Human settlements, flood events and a full circulation of the water body were important factors. The knowledge of these factors allows an optimized treatment strategy to ensure a high drinking water quality.

After the benchmarking process was established within the German water economy both in wasterwater treatment and water supply as an important instrument for hard check and efficiency increase of companies, a task force took the initiative to develop a benchmarking version to run barrages. Together with the company aquabench GmbH and the IWW Water Centre in a first step a process pattern for deployment benchmarking was proved. The task force was motivated by successful results to advance the process pattern to benchmark absorbed cost. The outworking is described below.

The 100-year-old Klingenberg dam, the water source of Dresden, was renovated complex since 2006. In 2012 the refilling was carried out as test impoundment. There are long-term measurement series of structural monitoring available and it was required to define expectancy ranges and limits prior the refilling. Uplift pressure limits were exceeded during the refilling. The dam crest has significantly moved in the upstream-direction during the rehabilitation. The results of the analysis of monitoring data are presented and interpreted for three phases of operation furthermore the experiences of monitoring during refilling are summarized in the this paper.

In order to refurbish the Klingenberg dam, it was necessary to empty the reservoir towards the end of 2009. Prior to this, an alternative system had to be implemented and tested to ensure continuity of water supply to treatment works serviced by the reservoir. The alternative supply system was carefully phased and integrated within the existing infrastructure. To reduce the complexity of the construction process some parts of the project were separated and completed in advance. This article describes the implementation and experience gained during the process.

Dams and reservoirs are very Important for water management in Saxony/Germany. They fulfil multifunctional purposes in the most cases. Their safety must be in accordance with the rules of technique every time. Their operation is subjected to a continuous process of changing natural and socioeconomic conditions and circumstances. The measures for adapting the dams to these developing requirements realised during the last twenty years in Saxony will be presented.

Levelings are predominantly carried out for the monitoring of the height of dams. Geometric levelings are usually used outside the dam structure. Hydrostatic levellings are frequently carried out in the constructions themselves. After several years of comparison measurements at the Dröda dam in Saxony, it could be determined, that under certain conditions the geometric leveling is an alternative to the hydrostatic leveling.

The Operation Upper Elbe Valley of the State Reservoir Administration of Saxony (LTV) is planning the restoration of the safety against overtopping of the Malter dam by expanding the spillway and the increase in the hydraulic capacity of the valves in the diversion tunnel. Due to the special structure geometries a hydraulic model test at a scale of 1:25 was necessary to review and optimize the performance of the preliminary design. Due to investigations of several component variants, as well as adjusted operating recommendations the preliminary design has been optimized and an effective convey of discharge has been proved.

During the flood of August 2002 the Eastern Ore Mountains was one of the main areas of damage. On the basis of the Saxonlan flood prevention concept for the river Rote Weißeritz and subsequent studies the State Reservoir Administration of Saxony planned a flood retarding basin within the Pöbelbach Valley. This flood protection project is implemented at the moment. The engineering work is classified as large basin according to DIN 19 700-12 and is designed as ecological permeable green basin. The barrier consists of a rockfill dam with asphaltic concrete core. The river Pobelbach is lead through the dam by an ecological passage. State road number S183 remains within the reservoir and is routed through the dam by a tunnel consisting of reinforced concrete.

The Klingenberg Dam has been refurbished to enhance its structural integrity. It also has been upgraded to meet the required technical standards for dams and reservoirs. The availability of the water supply during the construction period had to be ensured. Therefore, an alternative water supply system linking the Klingenberg system with two water works has been established. This article discusses the process of planning and executing the refurbishment of the Klingenberg Dam from the operator's perspective. It describes the experience the State Reservoir Administration of Saxony gained during this process as well as during the testing and refilling phase of the finished reservoir, which altogether lasted about 18 years.
