ISTT launched a new educational webinar series, available only to society members. Dr John Matthews, Director of the Trenchless Technology Center (TTC) delivered a presentation on the findings from a recent study of the potential environmental impacts of steam-cured cured-in-place pipe (CIPP) installations. This comprehensive study collected real data from multiple projects using various sampling methods to determine the extent of any impacts. The objectives of the study were to both evaluate air emissions from steam-cured CIPP and determine potential impacts on workers. This was accomplished by directly measuring worker exposure to emissions for locations onsite or offsite. The installation sites represented a range of scenarios typical of CIPP installations. Dispersion of the emissions was modelled to estimate compound concentrations for a large set of scenarios and weather conditions. The potential health risks were evaluated based on appropriate health-based action levels using the measured and modelled data.
The webinar was very well attended with 100 registrations and attendees coming from 22 countries! ISTT have recorded the presentation and will make them available to ISTT members at a later date.
The next webinar in the series is taking place on the 17 December at 2pm (GMT) and will be presented by Dr Dec Downey. In this webinar Dec will be reviewing the developments in UV Cured CIPP Lining from its introduction in 1985.
Overview: UV Curing for Cured in place pipelining was developed and launched in the UK and Sweden by Insituform Group and INPipe AB in the mid1980s. It took some time to establish but over the past twenty years has made a major contribution to the growth of CIPP worldwide. It offers certain advantages over more traditional curing methods but requires investment in technology, quality management and skilled operators to take full advantage of its potential. This presentation will provide an appraisal of the technology and a glimpse at what the future may hold. The webinar is available for members of all affiliated societies to register.
