In 2019, 93% of the sewer liner samples (CIPP) submitted for inclusion in the IKT LinerReport achieved all the required material characteristics. But, seven percent of samples failed at least one of the four tests. So there remains a residual risk.
Our latest IKT Compare technology evaluation is examining the performance of lining systems for the trenchless rehabilitation of pressure sewers. The aim is to support sewer network operators in the selection of suitable systems and to provide them with certainty when developing tender documents, overseeing installation, accepting the work, and monitoring quality. There is still the opportunity for sewer network owners from other countries to join a partner project to…
Sewers and tree roots—this gets the alarm bells ringing for pipe network operators, because with root ingress, for example into sewers is something they are struggling with almost daily. In other networks, such as district heating, gas or drinking water, the roots around pipes are more problematic, as they can transfer enormous loading during storms, for example. You don’t want roots in the pipe trench and especially within the pipes. …
For more than ten years, the performance of CIPP liners continuously improved. But, in recent years the annual test results have sometimes been poorer. Is this a sign of a reversal in that trend?
Today, Roland W. Waniek, Managing Director of IKT, celebrated his 20th job anniversary with IKT. He said: “These have been 20 exciting and intensive years. I would like to thank all employees and the Board Members for such good and successful collaboration over that time! And I look forward with confidence to the future.” Then he cut the cake.
IKT is building a globally unique test facility for heavy rainfall and urban flooding. The project, which costs around 11 million euros, is funded from the EU’s and North Rhine-Westphalia’s joint Fund for Research Infrastructures. NRW Environment Minister Ursula Heinen-Esser now visited IKT and presented the million-dollar funding decision. Overall objective: Preventing flooding from local heavy rainfall and protecting people and buildings.
