What is an acoustic sewer assessment?

An acoustic sewer assessment uses sound-based technology, such as the SL-RAT, to test 6-12 inch gravity sewer lines in minutes and determine which segments are flowing well versus which are blocked and need cleaning, without requiring CCTV or physical entry.

How is acoustic assessment different from CCTV inspection?

Acoustic assessment screens large amounts of pipe quickly and cheaply to flag which segments actually need attention, while CCTV provides detailed visual inspection of a specific segment. Utilities typically use acoustic screening first to prioritize where CCTV dollars should go.

What pipe sizes can the SL-RAT assess?

RH Borden's acoustic assessments cover 6 to 12 inch gravity sewer lines.

How does acoustic assessment save utilities money?

By identifying which pipe segments are already clean, utilities can stop cleaning pipe that does not need it and redirect that budget to segments that actually require maintenance, which costs a fraction of a traditional time-based cleaning program.

Can acoustic assessments help meet regulatory requirements?

Yes. A documented, condition-based assessment program using acoustic data can help utilities demonstrate compliance with state and insurance regulatory requirements for collection system maintenance.
