CP273  Managing CSO Screens to Reduce Risk of Failure Standards/Regulation
Project Appreciation and Objectives

There are now over 4000 screened Combined Sewer Overflows (CSOs) in the UK and at least another 2000 will be added in the next 5 years. Maintenance requirements for CSOs are highly variable due to different screen types, catchments, seasonal changes and installation arrangements. This variability means that maintenance applied on a scheduled basis alone is a poor match to the need, leading to excessive maintenance costs or risks of blinded screens and consent failure. CSO screens are, therefore, excellent candidates for monitoring to determine maintenance priorities.

A previous Portfolio project 'CP133 Reliable CSO Monitoring at Minimum Cost of Ownership' briefly considered the use of remote digital cameras with encouraging results. This project will look in more depth at the information requirements for monitoring CSO screens, and will run a 6 month trial to obtain tested cost / benefit data. The objective is to provide affordable monitoring systems for prioritising preventative maintenance and to alarm on failure. This approach will also encourage suppliers to develop appropriate products for this application.

Benefits

  • Improved risk management for compliance failure / incidents associated with screened CSO installations
  • Reduction in maintenance costs for CSOs, i.e. maintenance applied when needed
  • Real data on CSO screen performance to improve new designs and upgrades
  • Improved availability of monitoring equipment for water industry assets.
