Grey water rinse toilet
Provided is a grey water rinse toilet including a first reservoir configured to store a first water supply, a second reservoir configured to store a second water supply, a bowl having a first inlet fluidly connected the first reservoir and a second inlet fluidly connected to the second reservoir, a first valve disposed in the first inlet and configured to control a flow of the first water supply from the first reservoir to the bowl, and a second valve disposed in the second inlet and configured to control a flow of the second water supply from the second reservoir to the bowl. The flow of the first water supply may be configured to rinse an inner surface of the bowl.
1 . A grey water rinse toilet, the toilet comprising:
a first reservoir configured to store a first water supply comprises grey water;
a second reservoir configured to store a second water supply comprises fresh water;
a bowl having a first inlet fluidly connected to the first reservoir and a second inlet fluidly connected to the second reservoir;
a trapway connecting the bowl to a drain or soil pipe;
a first valve configured to control a flow of the first water supply from the first reservoir to the bowl, the flow of the first water supply being configured to rinse an inner surface of the bowl; and
a second valve configured to control a flow of the second water supply from the second reservoir to the bowl.
2 . The toilet of claim 1 , wherein the first reservoir and the second reservoir are disposed within a tank of the toilet with the first water supply and the second water supply fluidly separated.
3 . The toilet of claim 1 , wherein the first reservoir is disposed in the tank and the second reservoir is located separate from the tank.
4 . The toilet of claim 1 , wherein the second reservoir is disposed in the tank and the first reservoir is located separate from the tank.
5 . The toilet of claim 1 , further comprising:
a pump configured to pump the first water supply from the first reservoir to the first valve.
6 . The toilet of claim 1 , wherein the first reservoir is fluidly connected to a drain for a shower, a bath, or a sink.
7 . The toilet of claim 1 , wherein the first reservoir includes a filter, an ultraviolet (UV) light, or a chemical dispenser.
8 . A method of flushing a toilet using grey water, the method comprising:
opening a first valve disposed between a first reservoir configured to store grey water and a bowl of the toilet;
providing a flow of grey water to the bowl, the grey water rinsing an inner surface of the bowl;
conveying waste through a trapway connecting an outlet of the bowl to a drain or soil pipe;
opening a second valve disposed between a second reservoir configured to store freshwater and the bowl; and
providing a flow of fresh water to the bowl of the toilet.
9 . The method of claim 8 , wherein the flow of grey water is provided before the flow of fresh water.
10 . The method of claim 8 , further comprising:
filling the bowl of the toilet using the flow of fresh water.
11 . The method of claim 8 , wherein the first valve is opened for a first predetermined period of time and the second valve is opened for a second predetermined period of time.
12 . The method of claim 8 , further comprising:
collecting grey water from a shower, a bath, or a sink using a drain connected to the first reservoir.
13 . The method of claim 8 , further comprising:
treating the grey water with a filter, UV light, or a cleaning chemical.
14 . The method of claim 8 , further comprising:
pumping the grey water from the first reservoir to the first valve.
15 . A method of flushing a toilet using grey water, the method comprising:
sending, by a controller, a first control signal to a first valve disposed between a first reservoir storing grey water and a bowl of the toilet, the first control signal configured to open the first valve for a predetermined period of time, wherein a flow of grey water is provided to the bowl while the first valve is open, the flow of grey water being configured to rinse an inner surface of the bowl;
conveying waste through a trapway connecting an outlet of the bowl to a drain or soil pipe; and
sending, by the controller, a second control signal to a second valve disposed between a second reservoir storing fresh water and the bowl, the second control signal configured to open the second valve for a predetermined period of time, wherein a flow of fresh water is provided to the bowl while the second valve is open.
16 . The method of claim 15 , further comprising:
sending, by the controller a third control signal to a pump configured to pump grey water from the first reservoir to the first valve, the third control signal configured to turn the pump on.
17 . The method of claim 15 , wherein providing a flow of grey water to the bowl occurs before providing a flow of fresh water to the toilet.
18 . The method of claim 15 , wherein the first valve and the second valve comprise solenoid valves.
19 . The method of claim 15 , wherein grey water is collected from at least one of a shower, bath, or sink using a drain connected to the first reservoir.
