7 Why Use HDPE? LEAK FREE SYSTEM CORROSION RESISTANT REDUCED MAINTENANCE LONG SERVICE LIFE TOUGH/DUCTILE/FLEXIBLE SUPERIOR SEISMIC RESISTANCE

8 Water Research Foundation WRF IS THE WORLD'S LARGEST AND MOST WELL-RESPECTED RESEARCH ORGANIZATION DEVOTED TO DRINKING WATER RESEARCH...HELPS WATER UTILITIES, PUBLIC HEALTH AGENCIES AND OTHER PROFESSIONAL ORGANIZATIONS... RECENT EARTHQUAKES: IMPLICATIONS FOR U.S. WATER UTILITIES (#4408, 2012) JOHN EIDINGER G&E ENGINEERING SYSTEMS INC., OAKLAND, CA CRAIG A. DAVIS LOS ANGELES DEPARTMENT OF WATER & POWER

9 Concepcion, Chile 2010 History of quakes w/ significant damage 8.8 earthquake 3000 pipelines severely damaged Essbio began replacing pipelines in 2001 HDPE Pipes survived while other systems did not

10 CHRISTCHURCH, NZ FOUR 6.0 QUAKES IN 15 MONTHS Water System: 1700 line breaks in 1700 km CBD leveled, Extensive liquefaction New HDPE lines did not fail. All nearby pipelines failed 170 km PE gas lines all survived HDPE PIPES SURVIVED ALL 4 QUAKES

11 TOHUKU PREF, JAPAN 9.0 EARTHQUAKE AND TSUNAMI Fault displacement up to 260 vertical feet (O Rourke) Shaking lasted 3 5 min w/ cm, world axis shift Most Pipe failures caused by pulled joints 600 million times more powerful than Hiroshima NO HDPE FAILURES

12 Water Research Foundation Common Denominators THOUSANDS OF DEATHS BILLIONS IN DAMAGE SEVERE PIPE DAMAGE NO reported HDPE failures

13 US SEISMIC PERFORMANCE NAPA CA 2014 Napa does not use HDPE 6.0 Earthquake caused 132 bell and spigot Breaks Napa Sanitation had many miles of HDPE and NO HDPE failures

14 CORNELL UNIVERSITY THIRD PARTY VERIFICATION Dr. Thomas O Rourke Expert: - geotechnical engineering - earthquake engineering; - construction technology, - authored over 350 publications

15 SEISMIC FLEXIBILITY IF IT WORKS IN A QUAKE Large Scale Fault 4 Shift Rupture Simulation Four foot fault event 35 PIPE

34 C C an American National Standard PE 4710 resin recognized from 4 to 65 for Potable Water use. Pipe and fittings are considered leak free Safety Factor Change Working pressures are recognized to 335 psi. Enhanced surge capability 1.5 times pressure for regular surges and 2 times pressure class for occasional surges

39 Trench Width Requirements Greenlee Marker Balls Spaced Every 20 1 Above Pipe Nominal Pipe Size Trench Width <3" 12" 3-24" OD + 12" >24" OD + 24" e.g. 10 IPS needs 22 Trench = 22 min (24 bucket typ.) ASTM D2321

40 HDPE Embedment Requirements Nominal Pipe Size Max Particle Size 2-4" 1/2" 6-8" 3/4" 10-15" 1" >= 16" 1.5" e.g. 10 IPS permits Max 1 particle size ASTM D2321

43 Horizontal Directional Drilling Controlled borepath horizontal drilling Used for crossing rivers, lakes, roads, etc., and where open cut is not feasible or cost effective ASTM F 1962; PPI Handbook, 2 nd Ed., Ch. 12 PPI BoreAid Software FixedPositionReel Pipe Coil PipeStraightener/Rerounder Directional BoringMachine

44 Bore-Aid

45 Installation Loads Bore path curvature generally controlled by drill rod Pipe pulling load depends on friction between pipe and ground at entry pipe to bore hole friction weight of pipe / buoyancy (air vs. water filled) frictional drag due to slurry

50 Pipe Bursting Defined? The breaking of an existing pipe, expanding the broken pipe shards into the surrounding soil while simultaneously pulling in the new HDPE line

51 Pipe Bursting Benefits Installs a new seamless pipe Ability to upsize Eliminates up to 85% of excavation Follows the path of the existing utility Less disturbance to traffic patterns Often more cost effective than open trench replacement Proven technology with 70,000,000 feet installed worldwide

52 Key Pipe Bursting Benefit 20% - 40% less costly

53 Depth of Cover A minimum of 4 foot of cover should be used when upsizing 1 size Greater cover should be used if upsizing more than one size Or, do the math yourself: Head is 3 larger in Dia. then add upsize inches Head + upsize = X X * 10 = proper cover depth

54 Impact Zone Formula Head + upsize = X X * 10 = proper cover depth PRIMARY 80% HOST SECONDARY e.g. 1 Upsize w/ 6 Host Pipe and 8 HDPE. Head = = 5 5 x 10 = 50 vertical impact
