Name of the project: PiReP
PiReP (Pipe Rehabilitation Planning System) is a universal easy-to-use software environment, which supports decision-making relating to renewal of drinking water systems. The overall aim is to renew pipelines with regard to the future in order to prevent cracks. A line break can have various effects. When the damage is detected very late or even too late, even large quantities of water escape in the ground. That might cause flushing and subsidence of roads, rails or neighbouring buildings.
Water leaks rapidly have to be repaired because of high follow-on costs (closure of streets, obstruction of traffic, etc.) which are basically significantly higher than those directly costs caused the damage. Water supply companies have to plan and execute track-renewal operations more efficient because of increasing cost pressure.
Only through using the latest forecasting techniques and valuating methods combined with graphical analyses in GIS-Systems drinking water pipes can be utilised maximum and damages can be minimised as to their durability. For the first time PiReP implements such procedures in practical use.
While at the same time best possible using of life-time of the pipes renewal strategy, which is dedicated according to local frames can reduce yearly arising damages significant. The use of PiReP-supported planning provides the coordination of building sites whereby malfunctions can be avoid in public life preventive.
Innovative mathematical techniques methods for assessing the actual state, medium and long-term rehabilitation forecast and scenario analysis were prepared and implemented. Forward-looking care was taken in that forecasting results can be visualised and processed by connecting to GIS System. This fact backs future approaches for optimising with reference to positions of pipes. Running imports of injury data allow accurate forecast results.
