ASSEMBLY The emergency flood control equipment is typically shipped in 50 foot sections sealed in 55 gallon plastic containers. Tubes are 50 feet in length when they are filled (54 feet when empty) and the tubes are 19 inches in height. Larger lengths rolled on spools may be provided. Each section is inspected, tested and certified prior to shipping. Upon arrival on-site, a section that will form part of the bottom courses is laid out and filled with water. Other sections are added to the initial section, connecting to form a watertight seal and filled with water. Once the bottom course is completed, subsequent courses are added in the same fashion as required. After the flood waters have receded and the dam is no longer required, the system can be drained, packaged and shipped to an authorized distributor to be cleaned, tested, repaired if necessary, re-certified and repackaged. The emergency flood control equipment (US Flood Control Emergency Diversion Dams) has had extensive testing thoroughly at the University of British Columbia facilities. SETUP TIME It takes approximately 90 seconds to fill one tube with water using a fire hydrant and 3 minutes using a standard pump. STEP BY STEP ASSEMBLY:   STEP 1 It takes only two people to set up the flexible tube dam. Here you see two men rolling out the empty tubes getting them ready to be filled with water. Each tube is strapped together before being filled with water.   STEP 2 The picture to the left how three tubes laid out parallel to each other. Straps are in place and valves are open ready to be filled with water.   STEP 3 The bottom layer of the barrier pyramid is being filled with water one by one to its maximum capacity.   STEP 4 The team of two men are laying out the second level of the dam. They are ensuring that each tube is strapped together and is laid evenly and parallel to the bottom layer.   STEP 5 Work begins on the second layer by filling each tube with water until it reaches it maximum capacity.   STEP 6 After the second layer of tubes are filled with water, the third and final layer of tubes is laid out evenly and parallel on top of the second level.   STEP 7 Completion of the dam is finished. Six tubes stacked in a pyramid fashion make a very stable flood protection barrier. Total completion time is approximately 1 hour depending on the water fill method you choose.
