HDPE Pipe holds a dominant position in several markets in North America: natural gas distribution, oil
patch, mining, landfill and geothermal. So why are polyethylene’s municipal water and wastewater
market shares so much lower than these other industries? How has the polyethylene industry been
successful in growing...
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 : CHALLENGING THE 10% WALL THICKNESS RULE FOR HDPE MARINE PIPELINESAuthor(s) : Ilija Radeljic, Ebbe Smith
HDPE pipe can be relatively easily scratched during the manipulation on the site,
which is especially true for the marine pipelines. Installing the scratched marine pipe
with the S bend method presents a risk and repair methods are usually performed.
Currently, there is no standard defining the repair procedure, in...

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...

The City of Miami Beach owns and operates a 54-inch sanitary sewage PCCP force
main (FM) that was built in 1977. This FM is the only transmission pipeline for
conveying about 22 million gallons per day (MGD) of raw sewage to the wastewater
treatment plant. In 2012, the City identified structural deficiencies in the...
2021 Amsterdam : DEVELOPMENTS IN NORTH AMERICAN CONDUIT PRACTICESAuthor(s) : Tom Stewart, Richard Hicks, Patrick Vibien, Lance MacNevin
Arguably, broadband technologies have become as vital to society as water delivery, waste removal
and energy distribution. However, the role of plastic conduit in broadband is often overlooked within
the piping industry and society in general. HDPE conduit is an essential component to the build -out of
5G cell...
2021 Amsterdam : DRAINAGE HANDBOOK STRUCTURAL DESIGN PROCEDURE FOR CORRUGATED POLYOLEFIN PIPEAuthor(s) : Joe Babcanec, P.E., Dan Currence, P.E.
The newly released Drainage Handbook provides complete guidance on corrugated
polyolefin pipe. Perhaps the biggest contribution this new handbook makes to the
advancement of both HDPE and PP corrugated plastic pipe is the design procedure
presented. The design procedure reflects the industry’s recommended practice for...
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 : 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...
