Raising the Threshold for Pipe Performance and Sustainability
The Newsletter of the Mayors Water Council of the U.S. Conference
of Mayors has featured an article on the first industry-wide, peer reviewed
environmental product declaration (EPD) for water and sewer piping in North
America, which has been verified by NSF Sustainability, a division of global
public health organization NSF International. This internationally recognized
certification helps municipalities meet their green building and infrastructure
goals. The EPD can be useful to municipal pipe procurement officials as it sets
performance benchmarks and allows for life cycle comparisons between multiple
pipe materials.

The
EPD was developed in compliance with international environmental management
guidelines (ISO 14025) and benchmarks the impacts of seven PVC pipe products
across their life cycles. This includes PVC pressure pipe for potable water,
reclaimed water and sewer force main systems as well as PVC non-pressure pipe
for storm sewer and sanitary sewer systems. NSF Sustainability reviewed and
verified the life cycle assessment (on which the EPD is based) and EPD documents
to ensure that no unsubstantiated claims were made and that the EPD followed all
applicable rules.
Leaders in Transparency Reporting
The EPD pinpoints areas of greatest environmental impact as well as the
environmental benefits of utilizing PVC piping. For example, the use phase of
pressurized potable water pipe, during which pumps overcome friction to move
water through pipe, was found to contribute the greatest environmental impacts
throughout the product’s entire life cycle. The EPD also identified advantages
in this stage such as the smooth interior surface of PVC pipe that minimizes
friction and energy consumption. PVC pipe is also corrosion resistant and has a
proven durability in excess of 100 years, requiring less frequent replacement.
Environmental
impact categories analyzed include global warming potential, ozone depletion,
acidification, eutrophication, smog formation and cumulative energy demand. PVC
pipe is designed to minimize environmental impacts due to its corrosion
resistance, enabling long-term durability.

It was an extensive process to develop the life cycle assessment and the
resulting EPD documents, but well worth the effort. Buyers of PVC piping want to
see this data to help meet their sustainability goals and our members were
dedicated to making this possible. This industry-wide EPD reflects their resolve
to use science to drive manufacturing and product improvements and to be leaders
in transparency reporting.
PVC water and sewer pipe are available in sizes up to 60 inches. Find out why
