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.

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.

The present invention relates to collection of water after being exposed to the moonlight. The water resource for exposure under moonlight over any period of time and the storage of such collected water so obtained from any resource. The water resource collected and composed of but not limited to collection of water from resources like river, spring, rain, snow, well water, tap water, distilled bottled water, that is accumulated. The period during which water is exposed to the moonlight can have a combination of significance but not limited to: zodiac, religious, astronomical, calendar, astrological, numerology etc. Further, the exposed water obtained is packed and labeled based on the religious, astronomical, astrological, numerological significance classified or falling under the time when the water resource or the water stored in the container is exposed to the source of moonlight. The water resource collected and composed of but not limited to collection of water from resources like river, spring, rain, snow, tap water, dew, distilled bottled water, well water that is accumulated or placed.

A hydrostatic tank floor relief valve of a construction described herein provides for equalization of hydrostatic pressure of fluid in a storage tank with hydrostatic pressure of ground water surrounding the storage tank. A high efficiency grate located in a flow channel of the hydrostatic tank floor relief valve blocks debris from entering the storage tank during pressure equalization, yet does not reduce effective flow rates through a flow channel of a given diameter. The hydrostatic tank floor relief valve optionally includes an elastomeric seal surface and a stainless steel seat ring that reduce the likelihood of particulate matter disrupting valve operation, and provide a more reliable seal.

An underground water storage system has a system for preventing water invasion into the near surface soil layers, thereby preventing water intrusion which may be detrimental to desired surface uses for the land, such as agricultural, recreational, residential or commercial uses.

A rainwater collector to be mounted on a downpipe and including a saddle, a scoop, and a scoop support. The saddle is configured to be coupled to the downpipe. The saddle has an orifice configured to be placed opposite an opening formed in the downpipe. The scoop is configured to be introduced into the downpipe through the orifice of the saddle. The scoop support is configured to be mounted through the orifice of the saddle and to support the scoop inside the downpipe. The scoop and the scoop support are removably coupled to each other. The scoop support has a base and a bearing frame extending from the base. The scoop support further includes a tab extending from the base within the bearing frame. The tab being elastically deformable to form a clamp with the bearing frame and to hold the scoop between the tab and the bearing frame.

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.
