Working groups
WG A – Management for construction and rehabilitation strategies concerning water and gas supply systems
Convenor: Max HAMMERER
The network management for the improvement of the technical and economical situation covers the reduction of damages, the optimisation of hydraulic network management and the reduction of supply risks for infrastructure and private properties. The goal is the preparation of a decision support guideline for planning and organizing the operation, inspection and maintenance activities and also the rehabilitation rate of transport and supply pipes with the right materials and technologies under efficient and long term conditions.
WG B – Influencing of water quality by water reservoirs
Convenor: Peter FRENZ - DVGW
According to the European Standard EN 1508 there are different possible construction systems for drinking water reservoirs in order to obtain water quality and construction design.
The main objective of this group is the preparation of a best practice guide for the planning and rehabilitation of reservoirs with respect to a general framework of technical and hygienic aspects.
WG C – Strategies for reasonable and successful use of chemical disinfectants in drinking water systems – prevention of damages of construction products
Convenor: Wolfgang WERNER - TZW
Chemical disinfection of drinking water with chlorine, chlorine hypochlorite and chlorine dioxide are commonly used methods against the biological load.
The main objective of the working group is the collection of information and data based on the available knowledge for the creation of guidelines concerning determination of requirements and optimization of all involved processes in service pipes and building installations.
WG D – Corrosion and corrosion protection in sewer systems”
Convenor : open
In canalisation systems and waste water plants a lot of serious damages at pipes, concrete constructions and metallic installations are caused by the aggressiveness of the transported and treated media.
The goal of the guideline is to decrease these costs of the corrosion, to explain the damage mechanisms and prepare recommendations for corrosion protection in sewerage systems.
