Distributor Market Insight:

Why HDPE? “…. HDPE market will only continue to grow into

new specifications & applications.

HDPE pipe manufacturers have been closely

monitoring progress in application growth. They

are all investing resources into production

expansion.” distributor 2/23/15

Utility Market Insight: Why HDPE?

Beside excellent and on-time service ..

What does the customer want?

HDPE is an important material for us ….

We appreciate what [MAB] does to:

• Standardize materials

• Standardize installation procedures and

practices

• Provide education

• Support research

• Promote the proper uses and applications of

HDPE

We are excited to be a participating member in

advancing these important efforts 9

PPI – BoreAid http://ppi.boreaid.com

– Provide preliminary HDD design calculations

per PPI PE Handbook, 2nd Ed. / ASTM F962

– Provide an easy to use tool to assess

feasibility of using PE in HDD

– It’s FREE – but is not a final design

21

• Provide preliminary pressure

pipe design calculations per

AWWA / ASTM standards

• Very easy to use clarify design

calculations for PE & PVC pipe

• It’s FREE – but is not a final

design

Standardization of

Potable Water HDPE Pipe Sizes

28

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: • DIPS and PE4710 (with C906 adoption)

• Offer 4 PC: 100psi, 150, 200, 250

• Stripe everything blue

• NSF-61

• CC2 and CC3 material (Chlorine Categories)

Results in greater product availability (pipe, fittings, etc)

Major proposed edits:

• Eliminate all older resins and most DRs

• Eliminate ½” and 2.5” sizes

• Keep only PE 4710 and DR9/ IDR7

• Best Resource for

HDPE water and

wastewater design and

installation

• Will be updated with

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.“

AWWA addressed

hydrocarbon

permeation by

including a permeation

statement in all its pipe

standards:

• PVC (C900, C905)

• Steel (C200)

• Ductile Iron (C110)

• HDPE (C901,

• …

HDPE Permeation

Page 175, Par. 5: “… any PVC pipe that does

become permeated without bursting should

be replaced because remediation of the pipe

is not feasible.”

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.”
