Conveyance drain emitter

An emitter system for removing standing water from a conveyance line operatively connected between a downspout and a stormwater detention system, where at least a portion of the conveyance line is underground and is adjacent to a percolation region in the ground, the emitter system comprising:

• a vault assembly, where at least a portion of the vault assembly is adapted to be buried underground;
• a drain emitter comprising
• an emitter housing, and
• a flow control member supported by the emitter housing to define an emitter opening;
• wherein
• the drain emitter is adapted to be connected to the conveyance line such that
• a primary portion of the collected water flows to the stormwater detention system,
• a secondary portion of the standing water flows continuously out of the conveyance line through the emitter opening at a preset emitter flow rate, and
• the drain emitter is arranged within the vault assembly and above the percolation region;
• and
• the flow control member is displaced relative to the emitter housing to set the preset emitter flow rate such that
• the secondary portion of the collected water flows out of the drain emitter to drain standing water from the conveyance line, and
• the secondary portion of the collected water percolates through the percolation region.

A method of removing standing water from a conveyance line operatively connected between a downspout and a stormwater detention system, where at least a portion of the conveyance line is underground and is adjacent to a percolation region in the ground, the method comprising the steps of:

• providing a vault assembly, where at least a portion of the vault assembly is adapted to be buried underground;
• providing a drain emitter comprising
• an emitter housing, and
• a flow control member supported by the emitter housing to define an emitter opening;
• operatively connecting the drain emitter to the conveyance line such that
• a primary portion of the collected water flows to the stormwater detention system,
• a secondary portion of the standing water flows continuously out of the conveyance line through the emitter opening at a preset emitter flow rate, and
• the drain emitter is arranged within the vault assembly and above the percolation region;
• and
• arranging the flow control member relative to the emitter housing to set the preset emitter flow rate such that
• the secondary portion of the collected water flows out of the drain emitter to drain standing water from the conveyance line, and
• the secondary portion of the collected water percolates through the percolation region.

A rainwater conveyance system for managing water flowing through a conveyance line, where a first portion of the conveyance line is located above ground and a second portion of the conveyance line is located underground and above a percolation region in the ground, the rainwater conveyance system comprising:

• a vault assembly, where at least a portion of the vault assembly is underground and is located above the percolation region in the ground;
• and
• a drain emitter comprising an emitter housing and a flow control member, where 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, and
• the flow control member and the emitter housing cooperate to define an emitter opening through which the secondary portion of the collected water flows out of the drain emitter;
• wherein
• the drain emitter is arranged within the vault assembly and above the percolation region;
• and
• 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.
