1. A pipeline system, comprising:
a pipeline;
a liner arranged within the pipeline and thereby defining an interior of the pipeline, wherein a pipeline fluid is conveyed within the interior of the pipeline and a portion of the pipeline fluid permeates the liner as permeated fluid and enters an annulus defined between the liner and the pipeline; and
a venting system for removing the permeated fluid from the annulus, the venting system including an active reinjection system that includes:
a reinjection line in fluid communication with the annulus to receive the permeated fluid from the annulus;
a suction line extending from the reinjection line to receive a portion of the permeated fluid; and
a fluid pump that receives the portion of the permeated fluid and discharges the permeated fluid into the interior of the pipeline.
