Applied solutions

The system includes:

 

  • 6 groups of tanks – 1720 m 3 in total, all with similar equipment
    and metering
  • valve with electric drive and radar water level measurement,
  • 2 valves (supply and emptying of tanks) with electric drives,
  • separator with a bypass and a tank for oil derivatives,
  • hydrant feed pump,
  • meter of water quality and conductivity
  • water level sensors in tanks

The scope of work included:

 

  1. Development of a local precipitation model, local reference hyetograms and computer hydrodynamic models.
  2. Development of complete project documentation and obtaining the necessary arrangements, decisions, permits for the performance of the contract.
  3. Delivery and installation of the Bumerang Smart software along with the necessary equipment for its operation, controlling water retention rainfall:
     

    • electrically controlled drives on gate valves
    • quality monitoring of retained rainwater
    • network controlled valves
    • monitoring of the filling of the cross-sections of the rainwater drainage system below the tanks
    • installation of a rain gauge and a weather forecast monitoring subsystem
  4. Execution of construction works
  5. System implementation and user training
  6. The system will control and optimize the operation of the retention reservoirs installed along the existing storm sewage collectors using the latest weather data and specially created models hydrodynamics.
