Sewer blockages: Predicting the unpredictable

Published 23 November 2021

Event date/time: Tuesday, 30 November 2021, 16:00 – 17:00 GMT

The water industry is facing a huge challenge to reduce the number of flooding and pollution incidents that occur. Recent news articles and television shows have highlighted this issue and brought it to the attention of customers who may have previously been unaware that there was a problem.

There is a limitation on resources, both financial and labour, which means the reactive approach to solving these issues is becoming harder to take. To address this challenge, Anglian Water Services is utilising the near-real-time modelling system ICMLive to forecast flooding and pollution incidents. It has been found that most incidents can be attributed to blockages. Binnies was commissioned to develop and verify a methodology that could model silt and sediment generation dynamically such that Anglian Water Services could use the modelled outputs to:

  • apply threshold levels that when exceeded would trigger intervention so that they can react quickly and reduce potential incidents related to blockages
  • confirm and refine the current planned preventive maintenance and fat, oil and grease locations.

This webinar will provide

  • an overview of the innovative methodology
  • the findings and potential benefits
  • how this methodology could be rolled out across a wider area
  • possible future enhancements to the methodology.
