This webinar highlights the lessons learned from 1:1 scale evaluation of the performance of technologies available for the repair of lateral sewers, particularly the use of patch repairs, and repair of lateral connections.
Smaller diameter lateral sewers which connect properties to main sewers are often in private ownership for at least part of their length, but sewer network owners may own all or part of them and/or be responsible for providing advice to property owners concerning their repair. Poor connections to main sewers are often a cause of groundwater ingress into sewer networks.
This webinar considers the findings from several large scale 1:1 comparative evaluations of the performance of different technologies for the repair of lateral sewers and lateral connections undertaken at IKT on behalf of German sewer network owners. These had a particular focus on the ability of products to stop groundwater infiltration and identifying quality assurance measures to be considered to ensure that installed solution will work effectively.
It will cover:
• Background to the issues
• Comparative evaluation of lateral connection repair technologies
• Repair of lateral sewers, particularly the use of patch repair
