Standardization of Potable Water HDPE Pipe Sizes Feedback from utilities: • Lead times: too long/Not acceptable • Emergency repair pipe is not in inventory, etc. This slows HDPE acceptance in the industry

Standardization Example Standardize the 90% (4-24”) potable water: • • • • •

US Main Break • 250,000 – 350,000 main breaks each year • Cost per failure of 20” and larger ~$500,000
HDPE Lowest Main Failure Rate
http://plasticpipe.org/pdf/ukwir-national-mains-failure-database.pdf
HDPE Life Cycle Cost http://www.pepipe.org/uploads/pdfs/Life_Cycle_Cost_Study.pdf
HDPE lowest LCC due to: • Low failure rate + Low cost/ mile for repair/ replacement • Very low leakage rates and low water loss costs due to fused joints
”The United States preference to look strictly at lowest bid price could lead to serious consequences in the future with networks experiencing higher costs for repair and water loss and requiring faster renewal frequency of pipe installation as a result of the lowest upfront price approach.“ 40

HDPE Permeation AWWA addressed hydrocarbon permeation by including a permeation statement in all its pipe standards: • • • • •
PVC (C900, C905) Steel (C200) Ductile Iron (C110) HDPE (C901, C906) …
HDPE Permeation Page 7, Par. 2: “
Based on current literature, gasketed water mains (using SBR and EPDM), regardless of the pipe material used, are susceptible to permeation through the gaskets.” “… any PVC pipe that does become permeated without bursting should be replaced because remediation of the pipe is not feasible.” Page 175, Par. 5:
