Abstract: An improved method for storing and transporting arch-shaped stormwater leaching chambers includes positioning a group of nested chambers in an inverted “arch down” configuration upon a pallet to lower the center of gravity and stabilize the load, and using a pair of spaced cradle arms secured to the pallet to cooperatively position and support the palletized chambers against sideways rolling. Tie-down straps are then drawn through the natural saddle created by the inverted chambers and secured to the pallet, thereby reducing the required length and natural stretch of the straps over conventional methods. A lower center of gravity is therefore achieved, and load stability of the chambers is maximized during storage and transportation through more centralized weight distribution and an improved tethering system, thus reducing potential for injury and damage to the chambers during handling.
