Project F205:
Municipal PR activities on private waste-water systems

Posted 11. January 2014

0 Comments

In Phase 1 of this project for the Environment Ministry of the state of NRW, the tools and materials used to provide the public with information about private sewer pipes are to be refined. Various new mechanisms and tools are to be created or further developed for this purpose. In addition, an aid to decision making about the refurbishing of site drainage systems is to be developed to assist owners…

Comparative assessment of innovative inspection procedures and equipment for site drainage systems

Posted 10. January 2014

0 Comments

This research project involves the development of a test programme to comparatively test and evaluate the inspection procedures and equipment currently available for site drainage systems. Practical experience is to be gathered in pilot deployments in cooperation between the Meyer-Entsorgung disposal company and the City of Osnabrück. In addition, general recommendations for action to provide both the public and system operators with assistance prior to the actual inspection are to…

Project F238:
Infiltration tightness at materials changeover and transition points

Posted 09. January 2014

0 Comments

Comparative investigations performed at material changeover points are to be used to draft independent and impartial information on the infiltration tightness, installation and operational quality of repair procedures for sewer laterals. The refurbishing of such laterals is, in practice, frequently performed in conjunction with the refurbishing of main sewers, by means, for example, of CIPP liners, and this application is therefore of particular interest for comparative tests and analyses. Large-scale…

Project F237:
Optimising sewer cleaning

Posted 08. January 2014

0 Comments

The first phase of this project has examined the extent to which cleaning intervals can be extended, efficiency improved and savings generated, using synergies between the organisation of cleaning activities and modern technology. Field tests were undertaken at a Ruhr University Bochum sewer site and expert workshops and discussions with operators were organised at IKT. The influence of gradient, fluctuation in run-off, time of year, time of day and ingress…

Project F234:
Installation, operation and maintenance of central water-drainage systems

Posted 07. January 2014

0 Comments

Groundwater management in the Emscher region has increasingly gained in importance in recent years in view, in particular, of rises in the groundwater table caused by drain/sewer refurbishing projects and the influence of mining activities. Such rises in the groundwater table can result in widespread effects on structures and sites in the affected region, and thus harbour significant potentials for conflicts. It may therefore be necessary, depending on the local…

Project C347:
Root intrusion into waste-water sewers – passive preventative measures

Posted 06. January 2014

0 Comments

Measures to prevent root intrusion into waste-water conduits, drains/sewers and manholes are to be assessed and recommendations for action derived to assist engineering consultancies involved in the planning of networks. The IKT has researched the fundamental relationships between root growth and underground infrastructure in a number of research projects, and has been involved in the drafting of the (German-language) standard, “Trees, underground conduits and drains/sewers” (published in German as DWA…
