1 Ductile Iron Pipe Research Association Horizontal Directional Drilling (HDD) with Ductile Iron Pipe Springfield, IL "To the man who only has a hammer in the tool kit, every problem looks like a nail. Abraham Maslow January 25, 2012 Kansas City, Missouri 543 feet of 12-inch Why DIP for HDD? Strength for installation & operating loads Flexible restrained joints Hydraulic advantages Installation options (assembled-line line & cartridge) Locating pipe No effect with temperature change/ creep No inventory/ training issues Pipe wall impermeable to VOC s 95% recycled material Proven Longevity Pre-construction Planning Preliminary Studies Landscape along proposed route - Video Existing utilities and structures Sub-surface explorations Legal Acquisitions Right of Way Permits Permits for removal of trees, shrubs Environmental Permits Public Relations Keep property owners informed and up to date Plan for proper storage of materials, equipment, etc. 1

8 Minimum Allowable Radius of Curve Maximum Allowable Joint Deflection (degrees) Minimum Allowable Radius of Curve - 18 ft pipe (feet) Minimum Allowable Radius of Curve - 20 ft pipe (feet) Field Report - Journal April 2006 The polyethylene encasement used in the HDD installations was intact at every excavation point, and we had 30 excavations of pulled pipe for Installation of taps, fire hydrants, and valves. So there s no question of the polywrap making it though the pull. Steve Gerdes Water Director, Normal 8
