The amended European Drinking Water Directive requires mandatory risk management in water supply from the catchment area to the domestic installation.
In RISK_Plus, TZW and the company disy Informationssysteme GmbH are developing a new web-based software tool that supports all steps of risk management and risk-based sampling planning in a database and GIS-based manner. The methodological basis for this is DIN EN 15 975-2. The project builds on the results of the TRUST project, which was also funded by the BMBF.
First, risk management and sampling planning are fully integrated methodically in order to exploit synergies and avoid redundancies. Through partial automation of process steps and intelligent assistance functions, efforts will be reduced and error possibilities minimized. Import options for existing geodata, interfaces to laboratory databases, comprehensive catalogs and templates for hazards and proposed measures, intelligent plausibility and consistency tests, automated monitoring of measured values, etc. will lead to an overall solution that is both powerful and user-friendly.
In the project, conceptual and technical foundations for intelligent assistance in risk management and for the software integration of risk management and risk-based sampling planning are being developed in two methodological work packages under the leadership of the TZW. Two complementary work packages under the leadership of Disy implement the resulting specifications in professional software modules and an integrated overall prototype. This will be demonstrated and tested with real sample data from the practice partners and validated with users. A large German water supplier and an engineering firm for drinking water and hygiene technology act as associated partners.
