100 Year service life of polypropylene and polyethylene gravity sewer pipes

Polypropylene and polyethylene (collectively known as polyolefin) sewer pipes have been widely used for over 40 years and have an established track record for reliability, integrity and trouble free service. However their predicted overall life expectancy has been discussed for many years without a definitive answer becoming available. Following the conclusion of a major two year project coordinated by TEPPFA in conjunction with LyondellBasell, Borealis and TGM (Austria) that situation can now be changed. Designers, owners and operators can now be confident that polyolefin sewer systems will have an in-service life of at least one hundred years when materials, products and installation practices meet the appropriate requirements.
