An assembly for reusing greywater in a building for flushing toilet and other purpose to save the freshwater. The assembly includes a diverter to route a portion of greywater from drainpipes to a feed line. From the feed line, the greywater is collected in a pump tank. The pump tank has a pump that can lift the greywater from the pump tank to a storage tank positioned at a top level in the building, the pump tank is at the lower level in the building. A supply line transports the greywater stored in the storage tanks to the toilet tanks for flushing the toilet bowl.

Adaptive buildings and building envelopes having a system of structural members which also function as one or more selectively independent fluidic transport systems. Fluids to be transported such as air, rainwater, potable water, irrigation water, and/or gray water, are moved about the adaptive buildings via the various fluidic transport systems to locations disposed about the adaptive buildings where they are used as needed. Such fluids are also selectively filtered and cleaned by a plurality of filter plate systems disposed about the structure.

The present invention relates to a storm water management system comprising a first conduit, a storage device, a first well and a valve, wherein the storage device comprises a coherent man-made vitreous fibre module (MMVF module), wherein the MMVF module comprises an upper passage and a lower passage, wherein the upper passage is in fluid communication with the first conduit, and wherein the lower passage is connected to the first well by the valve.

The present invention comprises a self-contained mobile living space that mimics the amenities of an entire residential property in order to affordably house individuals, particularly in urban environments. All living necessities are fused into one micro-living platform, independent of access to existing structures, land space, electricity, or sewage hookups, allowing landowners to rent out space with limited effort. The wheeled foundation allows the assembly to circumvent some of the existing urban building codes. In preferred embodiments, the various elements are configured in such a way that separate areas for sleeping, leisure, bathing, cooking, and gardening can be had atop a single compact space, with the use of exterior space maximized to heighten the sense of spatial availability for the occupant. The invention provides a new alternative for affordable urban housing, exploiting available residential land without the expense, permitting, or effort associated with permanent construction on a non-portable foundation.

A flush toilet comprised of a tank having a first compartment for holding a first type of water, and a second compartment for holding a second type of water. The first compartment is separated from the second compartment by a divider that prevents the first type of water from mixing with the second type of water. The first type of water can be city water while the second type of water can be rainwater.

A system of components, which, when assembled, form a rainwater separator for a downpipe is disclosed. The system includes, among other things, a screen for fine filtering of the rainwater. In a first assembly arrangement, the parts are assembled to form a rainwater separator with the screen so that the filtered water can be used as non-potable water for the household. In a second assembly arrangement, the screen is omitted, so that the water obtained from the rainwater separator may be utilized for watering the garden, for example.

Drainage systems are limited in performance and difficult to maintain. A drainage system is therefore specified, comprising the following: at least one infiltration device (10, 40) adapted to receive fluid; a collecting device (30) which is in fluid communication with the at least one infiltration device (10, 40) and is adapted to receive fluid from the at least one infiltration device (10, 40) and to discharge it to a fluid system (4), wherein a gateway device (52) is provided, which is adapted to receive and transmit sensor data to a receiving unit (60); at least one sensor (6, 6′, 7, 11, 11′, 14, 31, 31′, 32, 33, 41, 44, 42, 45) is provided, which is communicatively connected to the gateway device (52) for providing sensor data.

An apparatus for controlling fluid flow, including a temperature sensitive material, having a first physical property at a first temperature and a second physical property at a second temperature, a device for controlling fluid flow, and a device for connecting the temperature sensitive material to the fluid flow control device. The connecting device may be configured so that the fluid flow control device is in a first position at the first temperature and in a second position at a second temperature. The temperature sensitive material may be aluminum wire or stainless steel wire. The temperature sensitive material may have the shape of an Archimedean spiral. The connecting device may be a motion amplifier. The first temperature may be a cryogenic temperature.

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.

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.
