An assembly for reusing greywater in a building for flushing toilet and other purpose to save the freshwater. The assembly includes a diverter to route a portion of greywater from drainpipes to a feed line. From the feed line, the greywater is collected in a pump tank. The pump tank has a pump that can lift the greywater from the pump tank to a storage tank positioned at a top level in the building, the pump tank is at the lower level in the building. A supply line transports the greywater stored in the storage tanks to the toilet tanks for flushing the toilet bowl.

The present invention relates to a water control system for the cold and hot water plumbing installations, for consumption or heating and gray water in a home, premises or building which increases water and/or energy efficiency of the installation by means of a method of operation which reduces the water consumption or energy used in its consumption and treatment: detecting and controlling water leaks, avoiding consumption of cold water which is produced while waiting for hot water to come out, reducing the energy required for consuming hot water, reducing consumption of water when it is used for the toilet together with a soap, foam or similar, measuring and controlling the proliferation of Legionella bacteria and other microorganisms, cleaning pipes and in general monitoring the control variables of a plumbing installation and its visualization and interaction by a user or a smart and autonomous IT system.

A shower head water collecting device includes a water collecting hanging component, a temperature sensing element, an assembling component, a solar panel, and a temperature displaying element. The water collecting hanging component is provided for a shower head to be hung thereon and collects the water spraying from the shower head. The temperature sensing element is disposed inside the water collecting hanging component to sense the temperature of water spraying from the shower head. The assembling component is mounted on top of the water collecting hanging component. The solar panel and the temperature displaying element are disposed in the assembling component. The solar panel is electrically connected to the temperature sensing element and the temperature displaying element, wherein the solar panel harvests the light energy from the outside and converts it into electrical energy to supply power to the temperature sensing element and the temperature displaying element.

A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.

A system for the automatic management of the wastewater and freshwater for recreational vehicles is disclosed. The system includes a plurality of sensors configured for monitoring a first volume of blackwater within a blackwater holding tank, a second volume of greywater within a greywater holding tank, and whether an egress conduit is attached to a sewage system. The system further includes a processor configured for receiving a plurality of first signals from the plurality of sensors and sending a plurality of second signals to at least one of a plurality of values within the system. The processor is configured for determining if the first volume and second volume exceeds a first predetermined maximum threshold and a second predetermined maximum threshold respectively, then transmitting one of the plurality of second signals to prevent matter and wastewater from entering at least one of the blackwater holding tank and greywater holding tank.

An ozone mitigation system reduces the amount of ozone that is expelled from a toilet or another water consuming appliance. The ozone mitigation system may include an ozone generator in communication with a tank of the water consuming appliance. An air source and a power source may be connected to the ozone generator. An ozone flow restrictor or ozone eliminator is operable inside of the tank and configured to modify a flow of ozone from the ozone generator through the toilet tank.

The invention relates to methods, systems and apparatus for distributed management of raw water and internal combustion engine (ICE) gas emissions generated during industrial operations. One aspect of the invention at least partially utilizes a hot gas air knife to increase or partially increase surface area between a raw water and a hot gas in order to vaporize a proportion of the aqueous phase of the raw water and concentrate contaminants within a residual raw water concentrate. The water vapor generated by the vaporization process may be demisted, discharged directly to the atmosphere or alternatively condensed and captured for use. Another aspect relates to how the liquids and gasses interact to continuously flush the surfaces of the system which may help mitigate scaling issues. The invention may help facilitate rapid transfer of ICE combustion gas particulate and ICE combustion gas chemicals onto and into the raw water as it concentrates.

An indoor grey water purification and reuse device, system and method for public buildings is disclosed. The grey water purification and reuse device includes a grey water storage tank, a grey water treatment assembly and a pneumatic reclaimed water tank assembly which are sequentially arranged from top to bottom. The grey water storage tank is used for storing grey water from one floor above collected by a grey water collecting device. The grey water treatment assembly is used for carrying out multistage purification treatment on the grey water in the grey water storage tank. The pneumatic reclaimed water tank assembly is used for disinfecting reclaimed water subjected to multistage purification treatment and supplying water to reclaimed water reuse facilities on the current floor of the building in a constant-pressure mode.

A recycling device (200) for recycling used water from at least one used water source (100, 101) is provided. The recycling device (200) comprises a first water tank (210) arranged to receive used water from the at least one water source (100), and sensor means (211) arranged to measure the water quality of used water in the first water tank (210). The recycling device (200) is characterized in that it comprises a second water tank (220) arranged to store used water within the recycling device (200), and a water pump (240) and one or more valves (231, 232, 233, 234, 235; 301).
