The present disclosure provides a sump drain apparatus comprising a drain inlet and a ramp coupled to the drain inlet comprising an incline plane configured to divert drainage water toward the drain bowl, wherein at least a portion of the ramp is configured to be positioned on top of a roof deck.

An ice backing flashing layer for a roof including an upper portion attachable to an upper surface of the roof, a lower portion attachable to a fascia portion of the roof, and a bend between the upper and lower portions attachable over an edge of the roof. A roofing system including a first underlayment layer and the ice backing flashing layer adjacent to and above the first underlayment layer. The roof system optionally including at least one of a second underlayment layer adjacent to and above the upper portion of the ice backing flashing layer, a drip edge layer adjacent to and above the second underlayment layer, or a third underlayment layer adjacent to and above the drip edge.

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.

A roof drain including a flange defining an opening having a central axis, and a throat extending axially from the flange to define a channel having an inner surface therethrough. Where the throat includes a first end generally corresponding with the flange, and a second end opposite the first end, and where the second end is configured to be coupled to a drain outlet. The inner surface of the channel includes a cross-sectional shape taken normal to the central axis, and where the cross-sectional shape continuously and smoothly decreases or remains the same from the first end to the second end.

A drain cover assembly. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower flange or portion with a large area and extending outwardly in an arcuate configuration and having openings for fluid flow. The lower portion may be oriented at a small angle with respect to the horizontal. An upper portion may be connected to the lower portion and may be more vertically-oriented than the lower portion and also extend arcuately and having openings. Locking assemblies may be adjustable to secure the cover to a clamping collar over a drain. The locking assembly may include a base that slidingly engages the collar, and a housing that is secured over the base and to secure the cover to the collar.

An internal irrigation circuit board (10) 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), the connecting channel (4) conveying water accumulated in the drip irrigation channel (3) to the planting niche (2).

Drainage device for a construction, in particular a roof of a building or a terrace, for discharging rainwater, comprising: a drainage head (11) supported on the construction around a flow channel of the latter and defining a recovery space communicating with the outside and with the flow channel; and a mounting means comprising a support or attachment means (23) capable of being engaged inside the discharge channel and abutting against the peripheral wall of the discharge channel and a biasing means (24) which connects the drainage head and the support or attachment means and is capable of acting on the support or attachment means so as to keep the drainage head supported on the outer surface of the construction.

An apparatus for use with a rain gutter and a downspout has a first portion which rests in the rain gutter and includes apertures extending between an exterior and an interior of the insert to allow water to flow from the rain gutter into the interior of the insert when the insert is resting in the rain gutter. The insert further includes a second portion extending downward from the first portion. The second portion includes an interior in fluid communication with the first portion to allow the water to flow from the interior of the first portion through the second portion and into the downspout. The apparatus also includes an adapter plate having an aperture to receive the second portion of the insert such that the second portion of the insert can extend through the adapter plate into the downspout when the apparatus is in the rain gutter.
