A manhole channel liner includes a plurality of channel liner sections. The manhole channel liner routes the flow between at least two pipes that enter a wall of a manhole. Each channel liner section includes a flow channel formed in a top thereof. The plurality of channel liner sections are laid in the manhole to connect the flow from at least one inlet pipe extending through a wall of the manhole to at least one outlet pipe. The manhole channel liner is preferably held in place with a wet pour material, after thereof have been aligned. The plurality of channel liner sections may be retained in place with at least one alignment key.
