Concept For Optimized Flushing Of Potable Water Networks

To avoid discoloration events in water distribution networks a model for the calculation of optimized flushing intervals has been developed. The model is based on the network specific deposit situation as well as the hydraulic situation in the investigated network area and simulates the deposit growth in each pipe segment with consideration the mobilization. Together with the algorithm for the determination of the data base for the calculation, the model allows highly efficient network maintenance, which leads to a distinct reduction in customer complaints. The model was transferred in a self-running program that can be linked to any hydraulic simulation software. This enables a wide use of the research results under varying conditions.
