Definitions

  • THIS invention relates to a water supply management system.
  • the invention is concerned with a water supply management system for limiting flood damage in the event of equipment failure or resulting from human fault.
  • the damage caused by a burst pipe can be limited if the burst is detected shortly after occurring. This will normally be the case where the residents of a house are home and become aware of the problem when they detect an unusual amount of dampness in the vicinity of the burst pipe. If the residents are, however, not home when the pipe bursts it may be some time before the burst is detected and the necessary action taken. In the event that a pipe bursts when the residents are on vacation and the house is vacant for several weeks, the damage caused could be very severe.
  • a water supply management system comprising a sensor arrangement for detecting occupancy of a building, a valve for regulating water supply to a plumbing installation of the building and a control system for controlling movement of the valve in response to readings taken by the sensor arrangement.
  • the sensor arrangement comprises a motion detection sensor.
  • the sensor arrangement comprises a plurality a motion detection sensors for detecting movement in a number of rooms of the building.
  • valve is a solenoid valve.
  • control system will cause the valve to be located in an open position when the sensor arrangement detects movement inside the building while the control system will cause the valve to be located in a closed position when the sensor arrangement does not detect movement inside the building.
  • control system will cause the valve to be located in its closed position when no movement is detected by the sensor arrangement for a specified period of time.
  • valve is located in the main water supply to the plumbing system of the building.

  • FIG. 1 shows a water supply management system in accordance with the invention, generally indicated with the reference numeral 10.
  • the water supply management system 10 is installed for a residential building 12.
  • the building 12 has four rooms namely a lounge 14.1, a kitchen 14.2, a bathroom 14.3 and a bedroom 14.4.
  • the building 12 includes a plumbing installation 16 for supplying water from a supply network 18 of a municipality, via a main water supply 20, to sanitary equipment 22 and a geyser 24 of the kitchen 14.2 and the bathroom 14.3.
  • the water supply management system 10 comprises firstly a sensor arrangement, here provided in the form of four motion detection sensors
  • valve 30 in this embodiment a solenoid valve, is installed in the main water supply 20 and serves to regulate the supply of water from the supply network 18 to the plumbing installation 16 of the building 12.
  • control system 28 is programmable and will specifically be programmed such that when the motion detection sensors 26.1 , 26.2, 26.3 and 26.4 fail to detect any motion inside the building 12 for a specified period of time, the control system 28 will cause the valve 30 to move from an open position to a closed position. In the closed position of the valve 30, no water will be allowed to flow from the supply network 18 to the plumbing installation 16.
  • the motion detection sensors 26.1, 26.2, 26.3 and 26.4 will communicate to the control system 28 that movement has been detected and that the valve 30 can in response be located in its open position. Water will as a consequence be allowed to flow from the supply network 18, through the main water supply 20 and into the plumbing installation 16. Water that leak through the burst pipe can now be detected by the residents and they can take the necessary action to shut-off the water supply to the building and to have a plumber attend to fixing the burst pipe.
  • the water supply management system of the invention will not prevent a pipe or a geyser from bursting, but that it will limit the damage that could be caused if water is allowed to ensue uncontrolled through the burst for a prolonged period of time.
  • control system 28 is provided with a programmable timer 32 which can be set to allow the valve 30 to remain in its open position even though the motion sensors 26.1, 26.2, 26.3 and 26.4 do not detect any movement in the building 12. If the dishwasher will, for example, require an hour to run its cycle, the user can simply program the timer 32 such that the valve 30 will be caused to remain in its closed position until an hour has passed whereafter the valve 30 will be caused to return to its closed position.
  • the motion detection sensors 26.1 , 26.2, 26.3 and 26.4 will detect movement in the building 12 and the control system 28 will cause the valve 30 to be located in its open position and the supply of water to the plumbing installation 16 to be restored.
  • control system 28 includes an override timer 34 which will cause the control system 28 to open the valve 30 periodically for a small period of time in order to replenish the geyser 24 even though the building 12 is unoccupied.
  • the water supply management system 10 will be powered with electricity supplied from the electricity supply, not shown in the drawing, of the building 12.
  • the water supply management system 10 includes connecting means, not shown, which will allow it to be powered with a back-up battery, also not shown.
  • the water supply management system 10 includes a by-pass 36.
  • Burglar alarms employing motion detection sensors are employed in a large number of buildings for detecting unauthorised entry and for triggering an alarm. It is envisaged that instead of installing a number of motion detection sensors, the existing motion detection sensors of the burglar alarm system can simply be incorporated in the water supply management system of the invention to provide the required sensor arrangement. In such a system the control system .28 can, for example, be in electronic communication with a control unit 38 of the alarm system for detecting motion inside the building 12.
  • FIG. 2 shows a second embodiment of a water supply management system in accordance with the invention, generally indicated with the reference numeral 50.
  • the water supply management system is installed in a suite 52 of a hotel.
  • the suite 52 comprises a bedroom 54 and a bathroom 56.
  • a sensor arrangement 58 here motion detection sensors, are installed in the bedroom 54 and the bathroom 56 and are in electronic communication with a control system 60.
  • the control system 60 controls a valve 62 which will undergo movement between an open and a closed position in response to measurements taken by the motion detection sensors 58, thereby to control water supply in a plumbing installation 64 of the hotel.
  • the control system 60 In the event of the suite 52 being vacant the motion detection sensors 58 will not detect any movement with the result that the control system 60 will cause the valve 62 to be located in its closed position such that no water will be supplied to a plumbing network 66 of the bathroom 56.
  • the water supply management system of the invention could employ a plurality of valves which could be installed at any suitable position in a plumbing installation of a building.
  • the water supply management system may include measuring means for calculating the amount of water being supplied to a building from a main water supply of a municipality. It is pointed out that the water supply management system of the invention need not be employed for limiting flood damage in the event of a water pipe bursting only, but could be employed for limiting flood damage in the event of equipment failure or resulting from human fault.
  • a water supply management system in accordance with the present invention addresses the problem highlighted in the background portion of the specification.
