A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories. The system may collect, from the at least one sensor, signals indicative of water usage for substantially all water delivered through the distributed water infrastructure in a time period. The system may construct a plurality of water usage profiles in the aggregate, encompassing substantially all water delivered through the distributed water infrastructure in the time period. The system may assign each constructed water usage profile to one of the plurality of water usage categories. The system may output, for display, water usage for the time period for each of the plurality of water usage categories.

A water supply system for an aircraft has water lines which lead to a consumer group with at least one water consumer and at least one buffer upstream of the at least one water consumer. A discharge line discharges water from a water tank into the water lines and a feed pump in the discharge line supplies water from the water tank into the water lines. Each of the water lines is a flexible hose made of plastic with an internal diameter of at least 4 mm and a length of at most 100 m, and the feed pump is configured to convey water from the water tank into the water lines at a pressure of at most 25 bar and a flow rate of at most 1.4 liters per minute.

A flush-mounted group for mixing water for a bathroom or kitchen, comprising: a body comprising a valve, designed to be installed in a seat having a given depth with respect a finished surface, a fastening means for fixing the body to the seat, which is adjustable on the body to set the depth at which the body is inset inside the seat, a plate mountable on the finished surface to enclose the body inside the seat and which is provided with an opening for accessing the body, a control member for operating the valve, which is connected to the valve through the opening of the plate. The mixing group comprises a coupling means for connecting together the valve and the control member, which can be adjusted so as to vary a distance between the control member and the valve and ensure correct positioning of the control member inside the opening.

A water gathering and distribution system and related techniques for operating in freezing environmental conditions are disclosed. The system may include a water diverter unit or a water flow regulation unit configured to receive water from a water source situated at a location that is remote, inaccessible (or difficult to access), and/or experiences freezing environmental conditions and to deliver a controlled volume of that water for downstream use. The system further may include a water supply unit configured to receive that water and to supply it to downstream snowmaking equipment. In some instances, the supply unit also may cool the water to a temperature suitable, for example, for snowmaking. In a general sense, the disclosed system may be considered modular, in that multiple system components may be placed in flow communication with one another, as desired, to provide a distributed network of water collection and distribution elements.

A hot water unit fluid supply control system comprises a switching device coupled to a hot water unit, a rainwater tank and a potable water source. The switching device is configured to selectively switch between a first state, which allows fluid communication between the hot water unit and the rainwater tank, and a second state, which allows fluid communication between the hot water unit and the potable water source. The hot water unit fluid supply control system comprises a control unit configured to: receive fluid characteristic information associated with fluid in the hot water unit from one or more sensors; activate or deactivate a pump of the rainwater tank based on a comparison of a fluid characteristic parameter of the fluid characteristic information with requirements of the hot water unit to thereby cause the switching device to assume the first or second state.

A system is provided for tracking usage of a plurality of water appliances in a distributed water infrastructure. The system may comprise at least one processor configured to receive, from a location in the distributed water infrastructure upstream of the plurality of water appliances, historical water usage measurements; determine from the historical water usage measurements at least one unique water usage signature associated with each of the plurality of water appliances; receive, from the location in the distributed water infrastructure upstream of the plurality of water appliances, current water usage measurements; determine from the current water usage measurements at least one current water usage signature; compare the current water usage signature with at least one of the unique water usage signatures stored in memory to determine a match; and, based on the signature match, ascertain an identifier of a water appliance in current use.
