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.

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.

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.

Method for operating a water system (10). The water system (10) comprises a fresh water subsystem (11) being configured to provide fresh water to water consumers (13, 14, 15, 16, 17, 19), wherein first water consumers (13, 14) generate black water as waste water, and wherein second water consumers (15, 16, 17, 18, 19) generate grey water as waste water. The water system (10) comprises a waste water subsystem (12) being configured to receive the waste water from the water consumers (13, 14, 15, 16, 17, 19). The waste water sub system (12) comprises a waste water diverter (23) being configured to provide in a black water status of the waste water diverter (23) waste water to a drain (24) thereby treating waste water as black water, and provide in a grey water status of the waste water diverter (23) waste water to a grey water tank (22) thereby treating waste water as grey water. The method comprises the following steps: Detect by a fresh water controller (26) being installed in the fresh water subsystem (11) a fresh water consumption in the fresh water subsystem (11) and provide a respective first output signal to a grey water controller (25). Determine by the grey water controller (25) on basis of the first output signal provided by the fresh water controller (26) a control signal for the waste water diverter (23) to switch the same either into the black water status or into the grey water status.

A greywater control valve includes: a housing having an input port and at least two output ports; and an insert including a port connection element and a vent. A rotary greywater control valve includes: a housing including: an input port; a first output port; and a second output port; and an insert that rotates within the housing, the insert including: a connection channel that couples the input port to one of the first output port and the second output port; and a vent channel that couples the connection channel to one of the output ports. A fluid control valve includes: an input port located along a first axis; a first output port located along a second axis that is perpendicular to the first axis; a second output port located along the second axis; and a fluid channel that selectively couples the input port to one of the output ports.

This invention harvests abundant, highly usable washing machine rinse cycle water for irrigation and other uses. This is accomplished using two separate devices working together; it is comprised of a valve assembly (FIG. 2B), for diverting this rinse water to a collector and the collector (10) which improves the quality of the water, then distributes it. By closing a single valve (7) during the rinse cycle, the user is effectively watering the landscaping. The rinse water is regenerated during normal household washing so it is not dependent on rain. It does not use power nor does it depend on filters or storing water. It reduces the amount of city water required as well as reducing the volume of waste water generated.

A ball drain wye strainer valve assembly includes a wye strainer located adjacent to a T-ball valve within a unitary body. The ball drain wye strainer valve assembly includes an additional valve member. The combination of the valve members permits the flushing of the wye strainer screen from either upstream or downstream. A drain is also incorporated to allow for the system draining, flushing, or air-purging during the initial installation and subsequent maintenance of the screen and wye strainer.

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 diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.
