AOC Aliancys relines ageing pipe under Amsterdam

AOC Aliancys, working with contractor Insituform, restored drinking water supply in downtown Amsterdam after relining a 100-year-old cast iron pipe under a canal.

Water supply was disrupted when a potable water pipeline collapsed along with part of the quay near Nassaukade, a street on the banks of the Singelgracht waterway in Amsterdam.

The collapsed pipe was responsible for delivering drinking water to households at the centre of the town, so finding an alternative to supply the area was essential.

A 100-year-old unused 600 mm cast iron pipe was discovered running under the canal nearby, which was deemed suitable for conversion to a potable water pipe with proper relining.

“The customer initially thought that a brand new pipe would need to be installed as a permanent solution,” said Insituform Europe Research and Development Manager Ton van Geest.

“However, they realised this involved doing major construction work in a very busy part of the town.

“Because of the complexity of the operation, it meant that both road and water traffic would likely be blocked for several months.”

“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.”

AOC Aliancys Europe Head of Technical Service Rob van de Laarschot said that Insituform and AOC Aliancys have been working together over five years to develop the relining technology used on this project.

“The liners are impregnated with the new styrene-free Beyone™ 700-T-01 FC resin from AOC Aliancys,” said Mr van de Laarschot.

“The ingredients of this resin are on the positive list for food contact applications, the resin is manufactured in line with good manufacturing practice, and resin and glass liner systems have been approved by Kiwa-ATA as a sign of quality and trust.

“Liners impregnated with Beyone 700-T-01 FC resin have already seen many successful installations for drinking water networks in several European countries.”

Insituform was able to reline the 50 m section of pipe within two days, with minimal impact on traffic and the environment.
