PE pipes for gas and water mains - A success story in Europe
David Walton, Borouge Pte Polyethylene Pipe Materials
Predrag Micic, Qenos Pty Ltd Presentation Overview Polyethylene pipes: Network Performance
CSIRO has completed an American Water Works Association Research Foundation (AwwaRF) project to investigate the long-term performance of Polyethylene water pipelines. Two main goals of the project: Paul Davis, CSIRO Facilitating the pipe system choice

Replacing London’s Victorian Water Mains
Bill Becker and Mike Shepherd – Thames Water Utilities Ltd This paper was presented at the International Conference of Plastics Pipes XIII Thames Water has embarked upon a programme to replace 1235 kilometres (772 miles) of these pipes over the 2005 – 2010 AMP (Asset Management Plan) period at a cost of £500 million ($800 million). This paper describes the rationale of a work targeting strategy, pipeline system selection and provide illustrations of the problems and solutions of carrying out a major mains replacement project in a congested urban area. UKWIR National Mains Failure Database
Steve MacKellar, Bodycote PDL, Manchester, UK This paper was presented at the International Conference of Plastics Pipes XIII In 2002 UK Water Industry Research Ltd commissioned Bodycote PDL to collate and maintain a database of all water main failures in the UK and develop a protocol for data collection of failure information. Whilst far from error free, the data represents an enormous step forward in the provision of a robust dataset to aid the understanding of buried infrastructure assets and their failure. The database in 2007 comprises 480,000 failure records and 350,000 km of water mains. The UKWIR National Mains Failure Database has resulted in co-operation of all the UK water companies in the sharing of data in an unprecedented manner. Assurance of confidentiality is thought to be the key to this success. Development Of A Whole Life Costing Model For Large Diameter Water Mains
Mike Shepherd, Thames Water, Alan Headford, GPS, Richard Jordan, TRL Ltd., This paper was presented at the International Conference of Plastics Pipes XIII In Europe it was decided to develop a whole-life costing model for large diameter water mains in which the full life cost of Polyethylene (PE), Glass Reinforced Plastic (GRP) and Ductile Iron (DI) water pipes within the range 400 to 900mm (16 to 36 inch) can be compared (N.B. it is possible to adjust the model to cover other size ranges). Ultimately, as water becomes more scarce, the durability and reliability of the system will be the governing factor – under these conditions the corrosion resistance and joint tightness of PE will make it the only choice no matter what the diameter. Gas Pipes - Qualification of Plastic Pipes for 10 Bar
Lars Synnerholm, National Inspectorate of Explosives and Flammables, Sweden This paper was presented at the International Conference of Plastics Pipes XI PE 100 pipes were introduced as a possibility for use for natural gas in Sweden and Norway. The authorities had no doubts that the pipes were suitable for what they were designed. The main issue was whether the pipes were suitable for the same proximity distances or if they had to be altered. This paper explains the philosophy behind the Swedish – Norwegian distance requirements and why the authorities accept that the PE 100 pipes may have the proximity distances already used for steel pipes.
