A water conservation system includes a showerhead, a water conservation tank, and a sensor. The system further includes a first valve configured to direct water towards the conservation water tank in an open position and configured to prevent water from flowing towards the conservation water tank when in a closed position. The system further includes a second valve configured to direct water towards the showerhead in an open position and configured to prevent water from reaching the showerhead in a closed position. A controller is configured to direct the first valve to the open position and the second valve to the closed position upon the detection of water flow by the sensor and the configured to direct the first valve to the closed position and the second valve to open position upon the occurrence of an event that occurs after the initial detection of water flow by the sensor.

The present invention relates to a connector (100) for a water system. The connector comprises an inlet connector (105), a connector body and an outlet connector (120) arranged in sequence. The connector body is open-sided so as to form a tundish having an open air gap between the inlet and outlet connectors (105, 120), through which water can fall in use. The connector (100) further comprises a sensor for detecting the presence of water within the connector body.

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). The pump (240) and one or more valves (231, 232, 233, 234, 235; 301) arranged in the recycling device (200) such that used water is able to be stored in the second water tank (220), or recycled out of the recycling device (200) from the first water tank (210) or from the second water tank (220), when the water quality of the used water is above a determined threshold level. Also, a method and a computer program performed and executed in the recycling device (200) for recycling used water from at least one used water source (100, 101) are also provided. Furthermore, a recycling system (400) comprising a recycling device (200) and at least one used water source (100, 101) and a recycling system (400) comprising a recycling device (200), at least one used water source (100, 101) and at least one water consumption device (100, 102) are also provided.

Apparatuses, systems, and methods for collecting utility meter data are described. An example system may include a flow controller and a server. The flow controller is configured to communicate with a water meter for a property and connected to at least one water outlet of a plurality of water outlets. The server is coupled to one or more infrastructure databases and the flow controller. The server includes a non-transitory computer readable media and is configured to execute instructions stored on the non-transitory computer readable media. The instructions include receiving water usage data from the flow controller and transmitting the water usage data from the water meter for the property to a water utility company.

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 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.

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 indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel. The wet channel is located directly above the dry channel. A first side of the dry channel is connected to a first opening with a fan and outside air.
