The present invention discloses a device for flow control of fluid in pipelines to various utility fluid outlets like water taps and the like by blocking fluid flow from pipeline to said utility fluid outlet when the flow exceeds a predetermined flow rate. In other word, the present invention discloses an automatic fluid flow controlling device for restricting and/or stopping flow of the fluid medium miming through the guiding means or the tubing system when fluid flow exceed a certain flow rate as well as stopping flow of the running fluid flow when fluid level in the vessel wherein the running fluid is being delivered reaches a certain height.

In one aspect, a water conservation apparatus is provided that includes a diverter having an inlet for being connected to a water supply, a primary outlet, and a secondary outlet. The apparatus includes an elongate water storage tank and a supply conduit configured to connect the secondary outlet of the diverter to the water storage tank. The elongate water storage tank has a height and a width perpendicular to the height that is less than the height so that the water from the secondary outlet of the diverter forms a column within the tank. The apparatus further includes a tap having an outlet and a valve, the valve having a closed position that inhibits water flow from the water tank to the outlet and an open position that permits water to be driven out of the outlet by the column of water in the tank.

The recycling device (200) is characterized in that it comprises a second water tank (220) arranged to store used water within the recycling device (200), and a water pump (240) and one or more valves (231, 232, 233, 234, 235; 301). The pump (240) and one or more valves (231, 232, 233, 234, 235; 301) arranged in the recycling device (200) such that used water is able to be stored in the second water tank (220), or recycled out of the recycling device (200) from the first water tank (210) or from the second water tank (220), when the water quality of the used water is above a determined threshold level. Also, a method and a computer program performed and executed in the recycling device (200) for recycling used water from at least one used water source (100, 101) are also provided. Furthermore, a recycling system (400) comprising a recycling device (200) and at least one used water source (100, 101) and a recycling system (400) comprising a recycling device (200), at least one used water source (100, 101) and at least one water consumption device (100, 102) are also provided.

A water drainage system includes an underground conduit, a pop-up drain emitter, and a turf cover. The underground conduit is configured to direct water away from an eavestrough that is secured to a building. The pop-up drain emitter is secured to an end of the conduit and has a lid. The lid is configured to transition from a retracted position to an advanced position to emit water from the underground conduit. The lid is disposed above ground in at least the advanced position. The turf cover is disposed above and adjacent to the ground and radially about an outer periphery of the pop-up drain emitter. The turf cover is configured to inhibit vegetative growth radially about the outer periphery of the pop-up drain emitter.

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 modified by a point of use water conditioner. Water may be modified at the point of use based upon pre-configured routines or manual user selections. Treatments performed on the water may include quality treatments, such as modifying the pH or mineral content, and may also include experience treatments, such as the addition of scents, colors, carbonation, or health and beauty supplements. Additives used during treatment are provided in cartridges that may be inserted and removed from the water conditioner. Cartridges may self-identify when inserted, to aid in compatibility and usability determinations and recycling/recertification processes.

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.

A water reuse device for reusing waste water discharged from a bathroom or a kitchen as toilet flushing water, including: a water collecting tank (10); a storage tank (20) receiving the used water stored in the water collecting tank (10) and having a water level sensor (21); a toilet water tank (32) located at a lower level than the storage tank (20) and having a first water level sensor (36) and a second water level sensor (35); a first pipe (22) connecting the storage tank (20) and the toilet water tank (32); a first solenoid valve (40) installed in the first pipe (22); a second pump (38) installed in the toilet water tank (32); a backflow prevention valve (34) provided between the second pipe (33-2) and the third pipe (33-3); and a water shutoff valve (41) provided between a water supply pipe (31) and the water pressure control valve (41-1).

Method for operating a water system (10). The water system (10) comprises a fresh water subsystem (11) being configured to provide fresh water to water consumers (13, 14, 15, 16, 17, 19), wherein first water consumers (13, 14) generate black water as waste water, and wherein second water consumers (15, 16, 17, 18, 19) generate grey water as waste water. The water system (10) comprises a waste water subsystem (12) being configured to receive the waste water from the water consumers (13, 14, 15, 16, 17, 19). The waste water sub system (12) comprises a waste water diverter (23) being configured to provide in a black water status of the waste water diverter (23) waste water to a drain (24) thereby treating waste water as black water, and provide in a grey water status of the waste water diverter (23) waste water to a grey water tank (22) thereby treating waste water as grey water. The method comprises the following steps: Detect by a fresh water controller (26) being installed in the fresh water subsystem (11) a fresh water consumption in the fresh water subsystem (11) and provide a respective first output signal to a grey water controller (25). Determine by the grey water controller (25) on basis of the first output signal provided by the fresh water controller (26) a control signal for the waste water diverter (23) to switch the same either into the black water status or into the grey water status.
