These are two 4' high AquaDams® connected together. The fill tubes come out the top of the attachment collar and are reduced in diameter from 4 feet to approximately 6 inches and then duct-taped to keep them from expanding. The extra length of the fill tubes is then folded over and tied around the wooden core of the AquaDams® to help keep them in place. Since the tubes are elevated, the water will be unable to run out.

This is a picture of several large AquaDams® joined together using 25' long attachment collars. The collars are made out of the same material and are the same size as the outer tube of the AquaDams®. The fill tubes come out the top of the collar attached to the previously installed AquaDam®.
