Getting ahead of storms with automatic blockage alerts for Wilmington's CSO system

Detecting and clearing sewer blockages before a storm hits is essential to avoid flooding. But staying ahead of potential blockages can also strain utility resources.

To manually maintain Wilmington, Delaware’s 41 Combined Sewer Overflows (CSOs), WWTP staff had to inspect each one five days a week, requiring substantial driving, traffic management, and safety risks. But an automated system viewer with blockage detection alerts changed that.

See how the Wilmington, DE team worked with Aqua DNA to:

  • Improve capture capacity to minimize the occurrence of CSOs
  • Clear a blockage in 2 hours that could otherwise have taken another 41 hours to detect
  • Dramatically reduce the number of staff hours needed for manual inspections

“Utilizing Aqua DNA’s system has led to significant time and financial savings, such as clearing a blockage within two hours of an alert, compared to an overflow that could have lasted another 41 hours.”
