Title: Sewer Manhole Rehabilitation – quality assurance and comparison of techniques
Speaker: Dr. Iain Naismith and Dipl.-Ing. Markus Gillar – Senior Research Fellows at IKT – Institute for Underground Infrastructure (Germany).
Overview:
This webinar highlights the lessons learned from 1:1 scale evaluation of the performance of technologies available for the rehabilitated of manholes, with a particular focus on sealing against groundwater infiltration.
The surcharging of sewer systems by groundwater impacts both their operation and that of the wastewater treatment works they connect to. Relining sewer pipes is part of the answer, but manhole shafts are also a significant pathway for infiltration.
This webinar explains the approach taken, at the request of German sewer network owners, to provide them with knowledge about the performance and limits of manhole rehabilitation technologies and what quality assurance issues they need to be aware of. It will also signpost attendees to where this information is publicly available.
It will cover:
• Sewer manhole functions and the issues associated with them
• How IKT went about examining rehabilitation, defining damage patterns and reviewing the market
• What was discovered about the performance of rehabilitation techniques
• Key issues for applying QA to installations
