StudyConfirmsLongLifeExpectancyfor Polyethylene PipeinMunicipalWaterSystems

IRVING, Texas--(Business Wire)--
The Plastics Pipe Institute, Inc. (PPI) today announced an ongoing study by Jana
Laboratories confirms 100+ year life expectancy for pipe made from polyethylene
(PE) when used in municipal potable water systems. The study is the latest
in-depth research commissioned by PPI investigating the effects of disinfection
on the lifetime of polyethylene pipes.

Interim report findings state PE pipe can last in excess of one hundred years
under most water quality conditions, service environments and disinfection
techniques. "One hundred year service life exceeds typical expectations; fifty
years is widely accepted as the usual benchmark," explained Tony Radoszewski,
executive director of the PPI.

"Polyethylene has been successfully used for water pipe in Europe and North
America since the late 1950`s due to its leak-free joints, durability,
resistance to galvanic corrosion, and long-term cost effectiveness. This
research, along with analytical projects conducted over the years by our
association and other entities, overwhelmingly provides evidence demonstrating
the superiority of PE pipe systems over historically-used materials,"
Radoszewski concluded.

Jana Laboratories, publisher of the study, is a world-recognized authority on
testing and evaluating the effects of disinfectants on pipe materials.
Compilation of the research is ongoing with a final report anticipated in 2010.

More information and links to the interim report can be found on the PPI`s
