A CIPP liner reel system for managing the utilization and deployment of CIPP liners. The CIPP liner reel system generally includes a frame connected to a reel and drive unit. The drive unit is connected to the reel to control the rotation of its core. This core contains an opening that provides access to a connector unit within the core. This connector unit can be used to connect the reel to the end of a CIPP liner using a strap. Rotation of the core causes CIPP liner to wind on to or unwind from the reel. The reel may also contain a left guide member and a right guide member to assist in controlling the process of winding and unwinding the CIPP liner. The frame may also include a tractor connector that enables the CIPP liner reel system to be coupled to and transported by a tractor without affecting its operation.
