Precast Trench System

Trenwa’s one piece trench system is an attractive alternative to the component system in those cases where a heavier trench system is acceptable and the customer desires longer laying lengths. Its bathtub shaped bas is available in standard 10 foot lengths, with openings in the walls, or with solid bottoms. Since the base provides both the bottom and the walls for the trench, the addition of the lids on top of the base completes the One Piece system.
