A rain water filter is disclosed. The rain water filter includes a horizontal inlet and a horizontally arranged residual water outlet which are slightly offset in relation to each other. A pipe with a longitudinal slot connects to the inlet and the pipe leads into the residual water outlet. An adhesive filter which is in the form of a tunnel-shaped half-shell is arranged below the longitudinal slot, where the lateral walls are the filter surfaces of the filter. Due to the adhesion effect, the water which flows past is suctioned inwards where it passes through the longitudinal opening into a tank and from there, for example, into a cistern via a filter water outlet. The water running off from the side walls is collected on the base of the hollow cylinder and from there is guided to the residual water outlet.

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.

A rainwater harvesting apparatus and system for an emergency shelter includes a platform defining an aperture. A threaded fastener is inserted through the aperture and is rotatable through the aperture. A planar panel assembly is fastened to the platform by the threaded fastener. The planar panel assembly is configured to move on the threaded fastener along a longitudinal axis of the threaded fastener as the threaded fastener is rotated through the aperture in the platform. A canopy is secured to the planar panel assembly, such that a segment of the canopy moves together with the planar panel assembly along the longitudinal axis of the threaded fastener as the planar panel assembly moves on the threaded fastener.

One or more devices for being received within a downspout of a rain gutter assembly are provided. The one or more devices may be provided for collecting rainwater flowing through the gutter assembly. One or more collection tanks for storing collected rainwater are also provided. One or more accessory devices for use with the one or more collector devices and the one or more storage tanks are also provided.

Individual honeycomb shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant honeycomb shape for maximized structural strength and material use efficiency. Internal hexagonal or square shaped modules are assembled and encased by external hexagonal or square shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal hexagonal or square shaped modules drain into external hexagonal or square shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.

A modular rainwater collection device for collecting rainwater includes a tank that is substantially box-shaped. The tank has a top, a bottom, a tongue end, a groove end and opposing sides. A female coupler is centrally positioned in the groove end and a male coupler, complimentary to the female coupler, is centrally positioned in the tongue end. A top knockout is positioned in the top proximate to the groove end, and a bottom knockout is positioned in the bottom proximate to the groove end. A screen is reversibly couplable to the top knockout. The tank comprises a plurality of tanks. The plurality of tanks is mutually horizontally couplable and mutually vertically couplable, such that the plurality of tanks forms a wall of tanks. Each of the plurality of tanks is fluidically interconnected.

A downpipe fitting for coupling between top and bottom ends of a downpipe. The downpipe fitting includes two parts connected together and rotatable relative to one another about a longitudinal axis thereof. The first part has an inlet, sized and shaped to couple with an outlet of a first section of the downpipe, above the downpipe fitting. The second part has an outlet which is sized and shaped to couple with an inlet of a second section of the downpipe, below the downpipe fitting. The inlet and outlet of the fitting define a flow path for rainwater therethrough. Rotation of the second section of downpipe below the downpipe fitting, about the longitudinal axis, is decoupled from the first section of downpipe above the downpipe fitting.

A device for monitoring evaporation capacity of a water surface evaporator in a process includes a water surface evaporator and a rain collector, the rain collector and the water surface evaporator having a same size of orifice area, height, and contour profile of a monitoring device. One side of the water surface evaporator is connected with a first measuring well through a pipeline, and another side of the water surface evaporator is connected with a first electromagnetic flowmeter, a water supplementing electromagnetic valve and an overflow electromagnetic valve through a water pipe. The water supplementing electromagnetic valve is connected with a water supplementing barrel through a water supplementing pipe. A water collecting barrel is installed below the special rain collector. A second magnetostrictive water level meter, a starting drainage switch and a stopping drainage switch are installed in the second measuring well.
