Water recycling system and method

Abstract

A device, system, and processor-readable medium for untreated grey water treatment and reuse are disclosed. Untreated grey water entering a building's plumbing system is tested for recyclability before it routes for treatment and reuse or disposal through a building's sewer line. Certain sensors decide how to route the untreated grey water through treatment in the device. Treatments to untreated grey water could include multi-level filtration and heating/cooling cycles for a prescribed time period to produce treated grey water meeting EPA-approved standards. Once treated, the treated grey water is routed to treated grey water tanks where it is stored for later use in a building's toilets and landscaping.

What is claimed is: 
     
         1 . A non-transitory processor-readable medium storing computer code representing instructions to cause a process for detecting untreated grey water, said code comprising code to:
 detect untreated grey water entering a plumbing system of a building;   
       detect an impurity in the untreated grey water via a first operational sensor, wherein the impurity comprises bacteria, viruses, chemicals, toxins, fertilizers, minerals, biological weapons, radioactive materials, or radioactive waste;
 detect the impurity in the untreated grey water via a second operational sensor; 
 routing the untreated grey water into a water heating device and a first output filter via a directional device, wherein the untreated grey water passes through the first output filter as an output of treated grey water, wherein the directional device is associated with the first operational sensor and the second operational sensor; 
 route the treated grey water via the output sensor to a plurality of treated grey water tanks for storage and reuse in the plumbing system of the building if the treated grey water contains an impurity at or below the threshold for an acceptable impurity level; 
 route the treated grey water via the output sensor to the sewer line through the plumbing system of the building if the treated grey water contains an impurity above the threshold for an acceptable impurity level; and 
 shut down the device via the output sensor if the treated grey water contains an impurity above the threshold for an acceptable impurity level. 
 
     
     
         2 . The processor-readable medium of  claim 1  further comprising code to:
 prevent untreated grey water from re-entering the plumbing system of a building from the device via a first backflow prevention device and a second backflow prevention device; 
 pump untreated grey water from the plumbing system of a building via the first water pump into the untreated grey water holding tank; 
 pump untreated grey water from the untreated grey water holding tank via the second water pump through a water heating device, a cooling coil, and the first output filter; and 
 pump the treated grey water tank from the first output filter to the plurality of treated grey water tanks via a third water pump, then pumping the treated grey water from the plurality of treated grey water tanks into the plumbing system of a building via the water pressure pump, wherein the plurality of treated grey water tanks comprises a first treated grey water tank, a second treated grey water tank, and a third grey water tank, wherein the plurality of treated grey water tanks are connected to the third water pump which pumps treated grey water from the first output filter to the first treated grey water tank, then the second treated grey water tank, and then the third treated grey water tank. 
 
     
     
         3 . The processor-readable medium of  claim 1  further comprising code to:
 sense the level of treated grey water in the first treated grey water tank via the first treated grey water tank volume sensor; 
 sense the level of treated grey water in the second treated grey water tank via the second treated grey water tank volume sensor; 
 sense the level of treated grey water in a third treated grey water tank via the third treated grey water tank volume sensor; 
 detect untreated grey water entering the plumbing system of a building from a shower or bathtub in the building via the shower sensor, wherein the untreated grey water draining from the bathtub or shower connected to the plumbing system of the building is sensed for impurity via the second operational sensor; and 
 detect untreated grey water entering the plumbing system of a building from a sink in the building via the sink sensor, wherein the untreated grey water draining from the sink connected to the plumbing system of the building is sensed for impurity via the first operational sensor. 
 
     
     
         4 . The processor-readable medium of  claim 1  further comprising code to:
 control a temperature of the water heating device via a temperature adjustment unit, wherein the temperature adjustment unit sends a signal to a computer panel, wherein the computer panel is integrated into a data processing system; 
 cool the treated grey water after the untreated grey water passes through the heating device, wherein the grey water is cooled for an appropriate amount of time to a preferred temperature range of 60° Fahrenheit, wherein the untreated grey water is heated via the water heating device to a preferred temperature range of 160° Fahrenheit to 212° Fahrenheit, wherein the water is heated for an appropriate amount of time to kill impurities in the untreated grey water, wherein the first output filter filters impurities from the treated grey water after the treated grey water exits the cooling coil, wherein the first filter comprises a membrane filter, a charcoal filter, a sand filter, or a polypropylene filter; and 
 store the cooled grey water via a water tank after the cooled grey water exits the cooling coil and before the cooled grey water enters the first output filter. 
 
     
     
         5 . The processor-readable medium of  claim 1  further comprising code to:
 select one of the plurality of treated grey water tanks to be filled with treated grey water; 
 select the plurality of treated grey water tanks to be filled in sequence with treated grey water, wherein the first treated grey water tank is filled to capacity with treated grey water, thereafter the second treated grey water tank is filled to capacity with treated grey water, thereafter the third treated grey water tank is filled to capacity with treated grey water; 
 select the plurality of treated grey water tanks to be filled equally until the first treated grey water tank, the second treated grey water tank, and the third treated grey water tank reach capacity at the same time; and 
 select to bypass the device and return the plumbing system of the building to its original functionality. 
 
     
     
         6 . The processor-readable medium of  claim 1  further comprising code to:
 filter an impurity from treated grey water via the second output filter after the treated grey water exits one of the plurality of treated grey water tanks, wherein the second filter comprises a membrane filter, a charcoal filter, a sand filter, or a polypropylene filter.
