CNDT provides a system for optimized pressure management in water networks of urban districts.
Urban districts receives water from water authorities in high pressure (around 6 Bar). Water distribution with such high pressure will cause:
1) increased use of water
2) more energy is needed
3) increased amortization of pipeline network
Water distribution company implements a "pressure management" policy and decreases water pressure in the district entrance point. It can be done by simple valve installed in control rom before district entrance. According to limitations of water authorities, water pressure in whole district must be kept above predefined minimum (2.5Bar in Israel). So, currently water engineers manually set the entrance water pressure to the minimum value that still will ensure that pressure predefined minimum is kept in whole district. In order to keep these settings on optimal value, the recommendation must be changed every day (since the customer water consumption might...

Water distribution company implements a "pressure management" policy and decreases water pressure in the district entrance point. It can be done by simple valve installed in control rom before district entrance. According to limitations of water authorities, water pressure in whole district must be kept above predefined minimum (2.5Bar in Israel). So, currently water engineers manually set the entrance water pressure to the minimum value that still will ensure that pressure predefined minimum is kept in whole district. In order to keep these settings on optimal value, the recommendation must be changed every day (since the customer water consumption might change and changes in the pipeline are possible).
CNDT provides an optimal recommendation for the pressure of the water in the entrance point. Setting this pressure will assure:
1) water supply according the demand only --> water saving
2) decreased energy in the process of water distribution
3) decreased pipe amortization due to keeping optimal proportion between pressure and flow.
Our software reads the daily flow data from 3 sensors installed in first and last points of the district network. Sophisticated statistical algorithm provides recommendations for the pressure for the next day. Being set on the valve controller, these pressures will guarantee the minimal possible values of the pressure in all district points. Such decreased pressure is gained by closing the pressure valve --> less water is supplied. Except of it, these values of pressure are recommended according an expected flow in this district, the proportion between the flow and pressure is set to be stable --> hydraulics shocks will be saved --> less amortization. The algorithm implements machine learning technique, it "learns" every day, so no changes in customer consumption or pipelines characteristics will be missed.
This system is installed in Eyn Hayam district, Haifa, Israel and saves a water waste (comparing to manual settings).
