Abstract
A method includes detecting, by a fresh water controller installed in a fresh water subsystem, a fresh water consumption in the fresh water subsystem and providing a respective first output signal to a grey water controller. The method includes determining, by a grey water controller based on the first output signal provided by the fresh water controller a control signal for the waste water diverter to switch the same either into the black water status or into the grey water status.

A method for operating a water system comprising:
- detecting, by a fresh water controller installed in a fresh water subsystem, a fresh water consumption in the fresh water subsystem and providing a respective first output signal to a grey water controller;
- wherein the fresh water subsystem is configured to provide fresh water to water consumers;
- wherein first water consumers generate black water as waste water;
- wherein second water consumers generate grey water or black water as waste water;
- wherein a waste water subsystem includes a waste water diverter configured to provide waste water to a drain when in a black water status;
- wherein the waste water diverter is configured to provide waste water to a grey water tank when in a grey water status;
- detecting, by a common flow sensor installed in the waste water subsystem, a waste water flow in the waste water subsystem and providing a respective second output signal to the grey water controller;
- and
- determining, by the grey water controller based on the first output signal provided by the fresh water controller, a control signal for the waste water diverter to switch the waste water diverter into one of the black water status or the grey water status;
- wherein the waste water diverter is switched into the grey water status with a first time-delay (Δt1) after detecting by the fresh water controller that there is fresh water consumption;
- wherein the waste water diverter is switched into the black water status with a second time-delay (Δt2) after detecting by the fresh water controller that there is no fresh water consumption.
A controller for operating a water system, wherein the water system comprises a fresh water subsystem being configured to provide fresh water to water consumers, wherein first water consumers generate black water as waste water, wherein second water consumers generate grey water or black water as waste water, a waste water subsystem being configured to receive the waste water from the water consumers, a waste water diverter, wherein the waste water diverter is configured to provide in a black water status of the waste water diverter waste water to a drain thereby treating waste water as black water, and provide in a grey water status of the waste water diverter waste water to a grey water tank thereby treating waste water as grey water,
- wherein the controller is configured to:
- determine, based on a first output signal provided by a fresh water controller, a control signal for the waste water diverter to switch the waste water diverter into the black water status or into the grey water status,
- wherein the fresh water controller is installed in the fresh water subsystem and is configured to detect fresh water consumption in the fresh water subsystem,
- wherein a common flow sensor is installed in the waste water subsystem and is configured to detect a waste water flow in the waste water subsystem,
- switch into the grey water status with a first time-delay (Δt1) after detecting by the fresh water controller that there is fresh water consumption;
- switch into the black water status with a second time-delay (Δt2) after detecting by the fresh water controller that there is no fresh water consumption.
A method for operating a water system comprising:
- detecting, by a fresh water controller installed in a fresh water subsystem, a fresh water consumption in the fresh water subsystem and providing a respective first output signal to a grey water controller;
- wherein the fresh water subsystem is configured to provide fresh water to water consumers;
- wherein first water consumers generate black water as waste water;
- wherein second water consumers generate grey water or black water as waste water;
- wherein a waste water subsystem includes a waste water diverter configured to provide waste water to a drain when in a black water status;
- wherein the waste water diverter is configured to provide waste water to a grey water tank when in a grey water status;
- determining, by the grey water controller based on the first output signal provided by the fresh water controller, a control signal for the waste water diverter to switch the waste water diverter into one of the black water status or the grey water status;
- wherein when fresh water consumption in the fresh water subsystem is detected by the fresh water controller:
- detecting by the fresh water controller a respective water consumer causing the fresh water consumption and providing a respective second output signal to the grey water controller,
- determining by the grey water controller based on the first output signal provided by the fresh water controller and the second output signal provided by a common flow sensor the control signal for the waste water diverter to switch the waste water diverter into the black water status or the grey water status;
- wherein if fresh water consumption by a dish washer or by a washing machine is detected by the fresh water controller:
- switching the grey water diverter into the black water status during a washing cycle (W) of the dish washer or the washing machine, and
- switching the grey water diverter into the grey water status during a rinsing cycle (R) and drying cycle (D) of the dish washer or the washing machine.
