AOC Aliancys and Insituform Restore Drinking Water Supply with Insitumain Technology
Published : May 15, 2026
After the collapse of a drinking water pipeline in downtown Amsterdam, the capacity of the potable water supply network to the town center was significantly reduced. Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment. Insituform worked closely with AOC Aliancys to develop this innovative relining technology.
“Insituform supplied a state-of-the-art relining system based on our Insitumain Technology, which is a proven solution around the world for renovating drinking water pipelines,” explains Ton van Geest. “Through this technique, we create a new, clean and resilient pipe inside the existing pipe. The composite pipe provides structural integrity, corrosion resistance, and can cope with water pressure fluctuations, ensuring a reliable network operation for many years to come.” The renovated drinking water pipeline was back in service within five working days without any impact to quality or reliability, and to the full satisfaction of the customer.
“The liners are impregnated with the new styrene-free Beyone 700-T-01 FC resin from AOC Aliancys. The ingredients of this resin are on the positive list for food contact applications, the resin is manufactured in line with GMP, and resin/ glass liner systems have been approved by KIWA-ATA as a sign of quality and trust.”, adds Rob van de Laarschot, Head of Technical Service, AOC Aliancys Europe.
