2021 Amsterdam : APPLICATIONS OF HDPE PIPING TO SUPPLY WATER TO RURAL VILLAGES IN MOROCCOAuthor(s) : Donald Swen, Leanne Pichay, Nicholas Vallin, Alice Wu, Jim Johnston
In the rural commune of Ait Bayoud, Morocco, two of the most remote villages in the area,
Ilguiloda and Izgouaren, live with water scarcity. To meet their water needs, women and
children walk several kilometers to the nearest spring each day, often multiple times a
day. Consequently, children cannot attend school...
2021 Amsterdam : CHEAPER AND BETTER NETWORKS REALISED WITH PRACTICAL DESIGN SOFTWAREAuthor(s) : Andreas Moerman, Flip van der Valk, Mirjam Blokker KWR, Tjakko Haaijer, Jan Vreeburg,
Drinking water companies with ageing networks are facing vast amounts of drinking
water network reconstructions during the coming decades. This development coincides
with the energy transition, which puts pressure on the available space underground.
These external drivers give drinking water companies an opportunity...
2021 Amsterdam : LONG-TERM DURABILITY OF NEW POLYMER COMPOSITE VALVES FOR DRINKING WATER NETWORKSAuthor(s) : Jennifer Ravereau, Jose Teixeira Pinto, Malena Bernabeu, Jose Alacid, Jean-Philippe Le Goff, Frederic Mohier, Benjamin Rabaud
Drinking water network fittings such as valves are made of brass materials known to be robust over
long periods. Due to the gradual inflation metallic raw material costs, composite plastic valves have
grown in market share. Uncertainties remain, however, on their long-term reliability.
The aim of this work is to...
2021 Amsterdam : MODELLING THE MIGRATION FROM PVC-U PIPES INTO DRINKING WATERAuthor(s) : C. Losher and P.V. Mercea
In the framework of the German Environmental Agency (UBA) requirements of
plastic articles in contact with drinking water (KTW-BWGL-guideline), the
compliance is verified by comparing so-called “expected concentrations at tap”, C tap ,
of substances contained in the plastics with specific limits in drinking water...
2021 Amsterdam : MUTUAL RECOGNITION OF THE CERTIFICAT ION SCHEMES IN EUROPEAuthor(s) : Horst Stimmelmayr, Peter Sejersen
The voluntary certification scheme for plastic multilayer piping systems for hot and cold
drinking water inside buildings is a joint effort of two key European organizations. It was
initiated in close cooperation with the Brussels based European trade association of
plastic pipe and fittings manufacturers, TEPPFA....
2021 Amsterdam : PVC PIPES WITH SUPERIOR ROOT INTRUSION RESISTANCEAuthor(s) : Argnani Claudio, Ing. Gianpaolo Contarini
...Clogging of the pipes can be experienced in sewer systems after a short period of
service, due to the intrusion of roots from plants and trees. Plants, and in particular
their roots, are attracted by the water flowing inside the pipes. These roots will strain
the connections between pipes, in particular the sockets...
2021 Amsterdam : Risk Assessment of Non-Intentionally Added Substances (NIAS) in potable waterAuthor(s) : Dr Ruediger Liske, Dr Tobias Eltze, Dr Tania Weyland, Marie-Laure Bertet
The migration of NIAS (Non-Intentionally Added Substances) into potable water is a
recurring topic for the distribution of cold and warm drinking water and related materialsindustry. These substances are chemical compounds that are present in drinking water
contact materials but have not been added during the...
2018 Las-Vegas : A recent survey of water main failures in the US and CanadaAuthor(s) : Steven Folkman
A recent survey again confirms that PVC pipe has the lowest break rate when compared with break rates of ductile and cast iron, asbestos cement, steel, and concrete pipe. Other results of interest to water utilities and engineers are discussed.
During 2017, Utah State University conducted a survey of utilities across...
2018 Las-Vegas : Design and qualification of PA-PERT pipe for oil and gas transportationAuthor(s) : Liang Yu, Akshay Ponda, Dane Chang
Following the development of US shale oil and gas production since 2007, the demand for thermoplastic pipes with better corrosion resistance, and lower installation and operation cost than carbon steel pipe, has been growing significantly. Nylon 12 has been qualified for hydrocarbon transportation in offshore flexible...
2018 Las-Vegas : Discover: plasticsAuthor(s) : Davidovski Zoran
To get a deeper insight in why plastic pipes systems in some cases are deselected by designers, installers and users, European Plastics Pipes and Fittings Association (TEPPFA) initiated a research including interviews in four pilot countries: Poland, France, Germany and the UK. The first phase was concentrating on...
2018 Las-Vegas : Extrusion of thick wall pipes using a new bimodal PE 4710/PE 100 resinAuthor(s) : Vivek Rohatg, Gregor Hiesgen, Mark J. Lamborn, Ashish M. Sukhadia, Douglas E. Simpson, David W. Borrego, Pamela L. Maeger
Maintaining dimensions within specifications is problematic for the extrusion of large diameter thick-wall polyethylene (PE) pipe (> 75 mm wall) due to sag caused by insufficient resin melt strength. However, sag can be controlled through careful resin selection and optimization of the pipe cooling process. This paper...
