Article: Charlotte Deploys New Acoustic Inspection Technology to Reduce Cleaning Costs and SSOs

The City of Charlotte, NC maintains more than 229,000 connections through 4,100 miles of sewer collection pipe. To address the challenge of maintaining this complex collection infrastructure, the Charlotte-Mecklenburg Utilities Division (CMUD) partnered with the University of North Carolina at Charlotte in 2005 to develop technologies for pipe inspection. The developed acoustic inspection technology, called SL-RAT, has inspected over 1 million feet of sewer pipe, demonstrating that the SL-RAT can quickly provide operators with valuable information on pipe conditions.

“We’re saving money and saving our time with the us of acoustics. You can see immediately what needs to be cleaned, so it takes the guesswork out and focuses your efforts.”

– Jon Beam, Environmental Program Inspector for CMUD
