The drain emitter is connected to the conveyance line such that a primary portion of the collected water flows into the at least one storage tank and a secondary portion of the collected water flows out of the conveyance line through the drain emitter. The secondary portion is removed at a preset emitter flow rate sufficient to drain standing water from the conveyance line to prevent freezing of standing water within the conveyance line.
