Iain Naismith and Markus Gillar of IKT will present and answer questions on the findings from a comparative evaluation of six systems for rehabilitating pressure sewers. This three-year, 1:1 scale project was undertaken on behalf of a group of German sewer network owners to help them understand the capabilities and limitations of a selection of available technologies for rehabilitating pressure sewers using Class A, fully structural liners. Two close-fit and four cured-in-place-liners were examined and the findings have been used to advise network owners on quality assurance measures they need to consider when embarking on pressure sewer re-lining projects.
