A rainwater conveyance system comprises a vault assembly and a drain emitter. At least a portion of the vault assembly is underground and is located above a percolation region in the ground. The drain emitter is connected to the conveyance line such that a primary portion of the collected water flows through the first portion of the conveyance line and a secondary portion of the collected water flows out of the second portion of the conveyance line through the drain emitter at a preset emitter flow rate. The drain emitter is arranged within the vault assembly, above the percolation region, and below the conveyance opening. The preset emitter flow rate is predetermined such that the flow of the secondary portion of the collected water out of the conveyance line through the drain emitter drains standing water from the conveyance line and the secondary portion of the collected water percolates through the percolation region.

A rainwater distribution system for storing and distributing rainwater includes a first container configured to store rainwater and having a bottom wall and a side wall; a planting container being elevated off of the bottom wall and within the first container, and having a planting container bottom wall and a side wall; a planting container support configured to elevate the planting container off of the bottom wall and within the first container; a cascade aperture having a cascade filter, the cascade aperture positioned on the side wall of the planting container, and allows the rainwater that enters the planting container to exit the planting container into the first container; and an outlet aperture positioned on the side wall of the first container and configured to allow the rainwater to exit the first container at a controlled rate.

A water distribution pipe comprises an elbow formation along its length, an aperture-defining formation defining an aperture in a radially distal wall of the elbow formation along a radius of the curvature of the elbow, and an openable closure that is mounted or mountable to the aperture-defining formation and that closes the aperture.

Drainage systems are limited in performance and difficult to maintain. A drainage system is therefore specified, comprising 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); and 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.

The present invention provides a complete-circulation-type bio-toilet system in which adjustment tanks capable of storing water to be treated are arranged before and after a septic tank, thereby enabling stable provision of the system without stopping the system even when the system is in heavy use. In a bio-toilet system 1 that performs microbial treatment on water to be treated containing filth and circulates the water to be treated as washing water, it is provided with: a raw sewage tank 3 into which the water to be treated containing filth discharged from a toilet 2 is fed; a first adjustment tank 4 that stores water to be treated 31 discharged from the raw sewage tank 3 while performing aerobic treatment thereon by aeration and discharges the stored water to be treated 31 by a pump 43; a septic tank 5 that performs microbial treatment on the water to be treated 31 discharged from the first adjustment tank 4; a second adjustment tank 6 that stores the water to be treated 31 discharged from the septic tank 5 while performing anaerobic treatment thereon and discharges the stored water to be treated 31 by a pump 62; a reaction tank 7 that decomposes organic matter in the water to be treated 31 discharged from the second adjustment tank 6; and a washing tank 8 that stores the water to be treated 31 discharged from the reaction tank 7 for use as washing water for a toilet bowl.

A precipitation reclamation system includes a downspout adapter configured to receive runoff precipitation from a precipitation channel for a structure. The downspout adapter is configured to attach to the structure at a vent that places an interior of the structure in communication with an area external to the structure. A reclamation chamber is disposed within an appliance housing. The reclamation chamber has a pump. A reclamation conduit extends from the downspout adapter to the reclamation chamber and is configured to direct the precipitation to the reclamation chamber to define reclaimed water. The pump is adapted to deliver the reclaimed water from the reclamation chamber to a portion of the structure for use.

A flow splitter including a first plate being immobile and a second plate being turnable with respect to the first plate. The first plate includes a central part, and the central part includes a slot and two side parts disposed at two ends of the slot, respectively. The second plate includes a first subplate and a second subplate, and the first subplate includes one end provided with a flange. The second plate is coupled to the first plate. The first subplate and the second subplate are disposed at two side of the slot; two sides of the second plate include two gaps. respectively. The two side parts of the first plate are disposed in the two yaps, respectively.

A water tower system having a catchment system to collect climatically-produced water and route the water to an output; a water mattress system fluidly coupled below to the catchment system to collect the water from the catchment system; an elevated water tower storage system fluidly coupled to the water mattress system to receive and store water from the water mattress system, the elevated water tower storage system is located at or below the water mattress system; and a water distribution system fluidly coupled to the elevated water tower storage system to receive water from the elevated water tower storage system and distribute the water to a predetermined location.

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.
