A toilet installed in a bathroom includes a toilet bowl and a tank coupled to the toilet bowl. The tank can contain fluid for the toilet bowl. A rear surface of the tank is flush against a wall of the bathroom such that there is no gap between the tank and the wall and a bottom surface of the tank is flush against a floor of the bathroom such that there is no gap between the tank and the floor. The tank extends longitudinally above and below the toilet bowl and laterally outward past the toilet bowl such that a first side surface and a second side surface of the tank define outermost side peripheries of the toilet.

A shower system includes a water supply conduit, a reservoir, and a valve actuator. The reservoir is fixedly coupled to the water supply conduit such that the reservoir and the water supply conduit are fluidly coupled. The valve actuator is configured for actuation between a first position in which water is supplied from the water supply conduit and a second position in which water is supplied from the reservoir. In some implementations, the shower system further includes a showerhead that is fluidly coupled to the water supply conduit and the reservoir such that water may be supplied from either the water supply conduit to the showerhead or from the reservoir to the showerhead.

The invention relates to a water-saving device which is fully automated and comprises a complete electronic control system, the possibility of connection to the aqueduct supply network and a hydraulic generator for saving energy. The device according to the invention communicates with a modular system that optionally reduces the water flow of the shower to 50% and diverts the other 50% to the storage tank, by means of the electronic interface. The device according to the invention is applicable in the construction industry.

According to embodiments of the present disclosure is a water delivery system that continuously flows and recirculates clean water, diverting only water that has touched a user's hands. No sensing is required to activate the water flow and the actions of the user effectively divert the dirty water to a drain. The water delivery system comprises a clean water outlet, a clean water inlet, a dirty water drain, and a circulation pump. A stream of water continuously flows from the outlet and is received by the water inlet if the stream is uninterrupted. If the stream is disturbed, such as by the hand washing activities of the user, the stream is diverted from the inlet and instead falls into a sink and into the drain.

There is described a drainage system comprising: an inlet pipe; and an energy dissipater comprising a dissipation chamber. The dissipation chamber has a dissipater inlet fluidically connected to the inlet pipe and a dissipater outlet arranged to discharge fluid from the dissipation chamber. The dissipater inlet extends between a first end and a second end. A wall of the inlet pipe extends tangentially from the dissipation chamber so as to define the first end and such that, in use, fluid is discharged into the dissipation chamber in a tangential direction, thereby inducing a circulating flow within the dissipation chamber about an axis of the dissipation chamber. The width of the dissipater inlet in a direction parallel to the axis decreases from the first end to the second end.

A water recirculating device, liter counter, and temperature regulator for showers, which allows the user to predetermine the water temperature required for any bathroom having cold water network and hot water network, whereby any water below the predetermined temperature is recirculated passing through the boiler of the house until it reaches the temperature preset in the device, wherein said device is composed of a housing, a temperature regulator, an LCD display, a LED ring, two water valves; a hot and cold water inlet; a three-way valve; a flowmeter connected to a pump; a thermostatic valve; a servomotor; and an integrated circuit board; and a method.

Disclosed are a method and system for vertically utilizing unconventional water source. The system includes a water collection unit, a water treatment unit, and a monitoring, regulation and reuse unit. The water collection unit is configured to collect rainwater and/or domestic wastewater; the water treatment unit is in communication with the water collection unit and configured to purify the rainwater and/or the domestic wastewater collected by the water collection unit; and the monitoring, regulation and reuse unit is in communication with the water treatment unit and configured to use reclaimed water obtained through treatment by the water treatment unit. The method and the system for vertically utilizing unconventional water source in the present disclosure have advantages of a simple structure, low costs, and high treatment efficiency, effectively save energy and water resources, and are suitable for decentralized treatment and recycling of urban domestic wastewater.

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.
