An improved liquid run-off disposal system is described having an infiltration chamber (72) with first and second sidewalls (74). In cross-sectional view the first and second sidewalls (74) each include an inner surface 76 and outer surface (78), and each sidewall (74) includes a plurality of integrated louvre-shaped apertures (80). In cross-sectional view each louvre-shaped aperture (80) includes an upper surface (82) and a lower surface (84) which are angled upwards from the outer surface (78) and protrude inwards from the inner surface (76) into the interior of the infiltration chamber (72). The upper and lower surfaces (82, 84) comprise a plurality of angled sections, the angled sections being arranged so as to form a substantially vertical flow path through a portion of the aperture (80). The angled sections of the upper and lower surfaces (82, 84) are arranged at an angle and of a length so as to substantially overlap when viewed in a horizontal direction. The overlapping region Y1 ensures that the apertures (80) will admit the exit of water but substantially inhibit the entry of soil wherein, in use, when liquid run-off is piped into the infiltration chamber (72) it can drain away through the apertures (80) and into the surrounding soil.

A stormwater management inlet prefilter for system use in green infrastructure which typically includes either biofiltration (e.g. bioretention, tree planters, gravel wetlands) or infiltration (e.g. leech fields, dry wells, infiltration trenches and basins) that both provide recharge of stormwater runoff to groundwater aquifers and treated discharge to surface waters. The system can be used as an edge of curb system, a drop inlet, or inline. The system can be used both in retrofit or new installations and extends the operating life and reduces the maintenance burden of stormwater management systems by filtering out trash and debris at the inlet. The system enables the simplified maintenance of stormwater management systems at the inlet in an accessible location with no special equipment required. Installation is simple and comparable to common catch basins and grates. Preferably, the system is made of pre-cast concrete, HDPE, and stainless steel and is resistant to rust and rot from corrosive winter runoff. No special equipment necessary and maintenance is simple and utilizes standard vacuum trucks for catch basin cleaning by use of a pressure washer and vacuum equipment.

A storm water drain system and methods of assembling the same are provided. The system can be arranged to provide a water management function such as retention, detention, conveyance, or infiltration. The system can include a plurality of support modules positioned adjacent to one another to form a top deck, a bottom deck, and an interior space between the top deck and the bottom deck. The plurality of support modules can include a support module that has a bottom corbel extending from an outer surface of the support module. The bottom corbel can be located within the interior space and have a surface that contacts a portion of the bottom deck.

A volume controllable toilet flush system, comprising: a cistern configured to hold and retain a fluid; a vertically moveable siphon assembly comprising a siphon portion, a pipe and at least one resilient element attached to the pipe; a toilet bowl shaped to retain and hold waste; an actuator operatively connected to the pipe by a stud attached to the pipe and configured to provide vertical movement to the siphon assembly, wherein movement of the siphon assembly by the actuator stores or releases energy in the at least one resilient element and, wherein downward vertical movement of the siphon assembly puts the toilet bowl in fluid communication with the cistern by creating a siphoning action between the siphon portion and the fluid in the cistern and wherein subsequent upward vertical movement of the siphon assembly terminates the siphoning action to stop fluid flow from the cistern to the toilet bowl.

A shower head flow control structure includes a water inlet assembly, a sealing seat, a primary flow restrictor, and a plurality of secondary flow restrictors. The water inlet assembly has a water inlet passage communicating with a water supply tube. The sealing seat haw a plurality of discharge holes. The inlet water passage communicates with one of the discharge holes. The primary flow restrictor is disposed in the water inlet passage. The secondary flow restrictors are disposed in the discharge holes, respectively. The primary flow restrictor has a flow rate greater than that of the secondary flow restrictors. The flow rates of the secondary flow restrictors are different from each other. The flow rate of the shower head can be controlled accurately and quickly.

Proposed is an automatic flushing device for an electronic bidet, in which the automatic flushing device has an automatic flushing function and is for both a water tank toilet and a direct flush valve toilet. In contrast to existing bidets, which are produced separately for the water tank toilet and the direct flush valve toilet in order to enable the automatic flushing function of the water tank toilet and the direct flush valve toilet, the automatic flushing device for the electronic bidet enables a single bidet to be capable of being used in both the water tank toilet and the direct flush valve toilet.

Methods, apparatus, and systems involving wastewater treatment systems are provided. The descriptions include a wastewater conduit with a pair of curved infiltrative surfaces. These curved infiltrative surfaces pass wastewater from within the conduit to outside of the conduit.

A shower head adapted to receive a supply of water from a water heater, the shower head including: a controller functionally connected to the water heater; and a height sensor functionally coupled to the controller, wherein the height sensor is configured to output a signal corresponding to the height of a user within a detection range of the height sensor, the height of the user is configured to correspond to a pre-determined setpoint temperature of the user, wherein the controller is configured for communicating the pre-determined setpoint temperature to the water heater for controlling the supply of water to the pre-determined setpoint temperature.

A shower system having an operating handle includes a positioning member, a ball joint, an overhead shower head, and a control mechanism. The positioning member has a water supply passage therein. The overhead shower head has an inlet end pivotally connected to the ball joint. The overhead shower head includes a handle portion protruding from a surface of the overhead shower head. The control mechanism is disposed on the handle portion and configured to control the inlet end of the overhead shower head to be in communication with an outlet end of the overhead shower head. The shower system is suitable for users of different heights, easy to operate, simple in structure and low in cost.
