A drainage device for a construction, e.g., a roof of a building or a terrace, for discharging rainwater, is provided. The drainage device includes a drainage head supported on the construction around a flow channel and defining a recovery space communicating with the outside and with the flow channel; and a mounting element having a support or attachment element capable of being engaged inside the discharge channel and abutting against the peripheral wall of the discharge channel. The device further includes a biasing element which connects the drainage head and the support or attachment element and is capable of acting on the support or attachment element so as to keep the drainage head supported on the outer surface of the construction.

A rooftop rainwater drainage assembly that is at least partially concealed from view from an exterior of a dwelling. In particular, the rooftop drainage assembly can include an opening spout secured to a roof deck region of a dwelling, and an elongated downspout having a first region disposed between an exterior wall and an interior wall of the dwelling and secured to the opening spout, thereby at least partially concealing the downspout from view from both the interior wall and exterior wall of the dwelling.

A roof drain including a base defining a channel and an axis, a gravel guard coupled to the base and including a plurality of teeth, where the gravel guard defines a plurality of gullets between the teeth, and a dome coupled to the base, where the dome includes a plurality of ribs, where the ribs define a plurality of gaps therebetween, and where each gap is radially aligned with a corresponding gullet.

An intelligent roof drain system includes a roof drain surrounded by a drain plate. A water seepage detection module is disposed proximate the drain plate. The water seepage detection module includes water seepage detection sensors and circuitry and an antenna system to inductively receive power and communicate water seepage data. A roofing membrane is disposed over the water seepage detection module. A monitoring module that includes control circuitry, power supply circuitry, water level detection circuitry, communications interface circuitry, and an antenna system to inductively supply power to and communicate with the water seepage detection module is disposed proximate the water seepage detection module such that the antenna systems align. The intelligent roof drain system can detect water seepage under the roofing membrane and standing water proximate the roof drain and communicate such events to a gateway and/or building management system.

This describes an internal irrigation circuit board (10) that comprises: a body (1), with a planting niche (2) adjacent to a drip irrigation channel (3) holding at least one drip irrigation hose (5), with the drip irrigation channel (3) functioning in cooperation with the planting niche (2) through a connecting channel (4) arrayed concurrently with the drip irrigation channel (3), said connecting channel (4) conveying water accumulated in the drip irrigation channel (3) to the planting niche (2).

The invention relates to a sealing ring including, axially, a main portion (2) and a secondary portion (3), connected by a weakened intermediate portion (4) which can be broken under an axial force applied between the main portion and the secondary portion, the main portion (2) including an annular sealing sleeve (5) and a projecting outer shoulder (6) arranged at the end of the annular sealing sleeve (5), opposite the breakable portion (4), and the secondary portion (3) including a projecting inner shoulder (10). Said annular sleeve (5) of the main portion (2) of the ring can be inserted between ducts (16, 17) that are inserted into one another, said projecting outer shoulder (6) of the main portion (2) abutting against the end of the outer duct surrounding the inner duct, and said projecting inner shoulder (10) of the secondary portion (3) abutting against the end of the outer tube that is inserted into the outer duct.

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.
