In the summer months, in particular, odour emissions from sewers cause odour nuisances and thus higher levels of complaints from residents. Sewer-system operators are in general obliged to find a remedy for such problems.

Odour filters installed in waste-water manholes are coming into increasing use. In addition, further products which release special active ingredients in the waste-water manhole shaft are also used. The aim of this Comparative Test was that of testing the odour filters for waste-water manholes available on the market together with the participating sewer-system operators for their fluid permeability, cleaning performance and easy usability, and to perform a comparative assessment of their quality. Products which release special active ingredients into the waste-air leaving such waste-water manholes for the suppression of such odours were also tested.

IKT has investigated the material quality and practical usability of CIPP liner products for sewer laterals in the context of an extensive programme of tests. Practically orientated tests performed in the test pipes at the IKT’s large-scale test facility were the focus of this programme. The IKT Comparative Test “Sewer lateral liners” provides drain/sewer operators with reliable and impartial information on the product properties of commercially available refurbishing procedures.

Many waste-water system operators are unsure of what can be achieved by main sewer repair methods and what quality is attainable. Twelve different techniques from the three groups of methods: “Injection/grouting + injection methods”, “Short-liners” and “Internal sleeves” have been comparatively tested under defined and replicable conditions using the IKT Comparative Test “Repair methods for main sewers”. The principal focus was the testing of the techniques in IKT test rigs under conditions approximating to actual practice. The IKT Comparative Test provides reliable and impartial information on the quality of the techniques tested and statements concerning the general suitability of the individual techniques and method groups

This IKT Comparative Test assesses the suitability and the practical usability of CIPP liners available on the market for sewer laterals. The central focus is on highly practically orientated comparison of the products, in order to be able to provide waste-water system operators with impartial and technically substantiated information on the strengths, weaknesses and potentials/limitations for use of the products tested. The test programme itself has been developed jointly with the participating system operators.

Damage to the lateral connections on main sewers is a frequent occurrence. Common types include intruding and detached damaged connecting lines and cracks and/or spalling around the lateral connections. Injection and top-hat section methods for the repair of sewer lateral connections have been tested to the limit in an IKT Comparative Test. The assessment criteria were the system tests performed by IKT in test lengths, the method suppliers’ Quality Assurance measures, and on-site tests.
