A drainage system, comprising a collector which is arranged to collect liquid and a drainage pipe having a pipe inlet that opens into the collector such that liquid collected by the collector drains through the pipe inlet. The drainage pipe is provided with a vent spaced away from the pipe inlet. The vent is arranged such that, when liquid collected by the collector occludes the pipe inlet, liquid flowing through the drainage pipe draws air into the drainage pipe through the vent.

A system is provided that includes a downspout upper and lower section whereby the lower section selectively pivots from a substantially vertical to horizontal position.

A rainwater conveyance system for managing water flowing through a conveyance line having a first portion located above ground and a second portion located underground and adjacent to a percolation region. The rainwater conveyance system comprises a drain emitter comprising an emitter inlet and an emitter outlet. The emitter inlet is connected to the conveyance line such that the collected water flows into the drain emitter and a drained portion of the collected water flows from the second portion of the conveyance line and through the emitter outlet at a preset emitter flow rate. The drain emitter is arranged such that the drained portion of the standing water flows to the percolation region. The preset emitter flow rate is predetermined such that the drained portion of the collected water flows out of the conveyance line and percolates through the percolation region.

A downspout diverter for rainwater collection that consists of a rotating diverter unit with a catchment gate that captures and redirects the flow of water to the outside of the downspout when it is turned to its horizontal upright position, and restores downflow when it is turned to its vertical open position. The device is easy to install and remove without disconnecting the downspout, and the small size of its port and fixtures effects a finished appearance to the downspout.

An insert (400) for a rainwater downpipe (300) is fluidly coupled between a first section (310) and a second section (320) of the rainwater downpipe (300). A rainwater reservoir (500) is defined within the insert (400) to store the rainwater received from the first section (310) therein. The rainwater reservoir (500) includes a side surface (510), a bottom surface (520) and an outlet opening (522) fluidly coupled to the second section (320). A valve element (530) is disposed within the rainwater reservoir (500) to allow or deny the passage of the stored rainwater in the rainwater reservoir (500) through the outlet opening (522). The insert (400) is characterized in that the side surface (510) of the rainwater reservoir (500) further defines a rainwater harvesting opening (549) adapted to allow access to the rainwater stored in the rainwater reservoir (500).

A system for controlling rain water flow includes a container having a top end and an opposite bottom end. A drain tube having a drain port is connected to the container. A cover tube slidably receives the drain tube. A magnetic latch is disposed between the drain tube and the cover tube. The system includes a fill configuration in which the magnetic latch is magnetically engaged and the cover tube covers and seals the drain port of the drain tube. The system also includes a drain configuration in which the magnetic latch is magnetically disengaged and the drain tube slides downward to expose the drain port.
