A water recycling system for reprocessing and reusing bathing water from a bath or shower. The bathing water recycling system treats and reuses water that overflows from a bathtub or shower pan. The used bathing water is captured and retained after use. The captured dirty water is then filtered and purified. The filtered and purified water can be redistributed back into the shower or bathtub for reuse alone or in combination with additional fresh water. The treated water may also be rewarmed prior to reuse. Unneeded greywater water is redirected to the drain for disposal.

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be modified by a point of use water conditioner. Water may be modified at the point of use based upon pre-configured routines or manual user selections. Treatments performed on the water may include quality treatments, such as modifying the pH or mineral content, and may also include experience treatments, such as the addition of scents, colors, carbonation, or health and beauty supplements. Additives used during treatment are provided in cartridges that may be inserted and removed from the water conditioner. Cartridges may self-identify when inserted, to aid in compatibility and usability determinations and recycling/recertification processes.

The present inventive concept relates to a system (100) comprising: a water recirculating device comprising: a heating arrangement (112) arranged in a recirculating path (108); a mixing valve arrangement (122) in liquid communication with an external ON water path arrangement (114), said mixing valve arrangement (122) accepting as inputs hot and cold water from a hot and cold water source respectively, said mixing valve arrangement (122) being configured to form temperature regulated water (120) by combining said hot and cold water, said mixing valve arrangement (122) comprising a user input interface configured to control a proportion of said hot and cold water directed to said external water path arrangement (114); and a reference temperature determining arrangement (130) configured to determine a reference water temperature of said temperature regulated water (120); wherein said heating arrangement (112) is configured to adjust a water temperature of treated water towards said reference water temperature.

A compact residential house is disclosed which includes a pre-fabricated installation panel serving as an outer wall of the residential house and a lifeline system pre-installed on an outer surface of the pre-fabricated installation panel, the lifeline system including a grey water system.

An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus includes a pre-rinse sink, a tank positioned below the pre-rinse sink to receive effluent from the pre-rinse sink, an outlet from the tank and leading to a pipe, a valve in the outlet having an open position and a closed position, a dishwasher having a drain connected to the pipe, and a control for the valve to be in its closed position when the dishwasher is discharging to the pipe.

An electric water-recycling shower system comprising a first heating element, a fresh water intake arranged to pass the first heating element, an intake valve to control the flow of water through the fresh water intake, a water output, and a shower waste, wherein during a normal mode of operation, the intake valve is configured to allow a flow of water from the fresh water intake to pass by the first heating element and out of the water output, characterised in that the system is adapted to switch between the normal mode and a recycle mode of operation, the recycle mode comprising a waste water intake, and a waste valve connected to the shower waste, wherein the waste valve is configured to close in order to allow collection of waste water for diversion of water through the waste water intake, past a heating element and out of the water output.

The present inventive concept relates to a system (100) comprising: a water recirculating device comprising: a heating arrangement (112) arranged in a recirculating path (108); a mixing valve arrangement (122) in liquid communication with an external ON water path arrangement (114), said mixing valve arrangement (122) accepting as inputs hot and cold water from a hot and cold water source respectively, said mixing valve arrangement (122) being configured to form temperature regulated water (120) by combining said hot and cold water, said mixing valve arrangement (122) comprising a user input interface configured to control a proportion of said hot and cold water directed to said external water path arrangement (114); and a reference temperature determining arrangement (130) configured to determine a reference water temperature of said temperature regulated water (120); wherein said heating arrangement (112) is configured to adjust a water temperature of treated water towards said reference water temperature.

The invention relates to a method and system for recycling domestic greywater. Greywater is drawn from a greywater waste pipe through an overflow pipe of a sanitary fixture, thereby, permitting greywater to be collected for reuse without the need for complicated and expensive retrofitting and/or reconfiguration of existing plumbing infrastructure. The system and method of the present invention can easily operate independently or be integrated with domestic utility systems to supply these utility systems with grey-water.
